Victory Ed Engine ~ Vertex Snapping & Instanced Static Mesh Editor

Media Fire Download Links

I include media fire links in the file description for more recent engine verisons!

File:VictoryEdEngine.zip

Installation of Victory Blueprint Library

You should install my Victory Plugin in the Engine/Plugins/Runtime folder of the appropriate Engine version.

You should always try to package for Development Win64 first, and Shipping Win32 as these are the only two platforms I support for those who do not have C++ access.

Detailed Description

Installation of VictoryEdEngine for Vertex Snapping

Plugin download (5.8 MB):

It is important to do all of these steps in order

1. download my editor / BP plugin and put in a directory directly off of your main project directory called "Plugins"

spelling must be exact

2. Load UE4 editor and go to Windows->Plugins

3. Find my plugin and make sure it is checked as being active

4. maybe double check #3

5. close the editor.

6. go to YourProject/Config/DefaultEngine.ini

7. add these lines:

 [/Script/Engine.Engine]
 UnrealEdEngine=/Script/VictoryEdEngine.VictoryEdEngine

(Please note these instructions are only for VictoryEdEngine plugin, Victory Plugin does not need this as it is a runtime/packaged game plugin that does not modify the editor)

8. Load UE4 Editor again

9. click on any static mesh actor

10. You should now see the Victory Editor HotKeys button in the top left

11. If you hover mouse over this title area any time, you can get the list of hotkeys

12. Enjoooy!

What does this all do?

My plugin includes an alternative UnrealEdEngine class, that makes use of my new additional FEdMode editor mode class.

The config file tells the main UE4 binary to use my alternative UnrealEdEngine class instead of the default.

Commenting out the line you added will instantly disable my Editor Mode.

Unchecking my plugin in Windows->Plugins within the editor, but leaving the config file set,

is pretty much guaranteed to cause a crash.

soooo

Disabling My Editor Mode / Entire Plugin

To disable my editor mode you should *always* comment out the DefaultEngine.ini line first!

Then you can load the editor again and disable the plugin entirely

My plugin cannot corrupt or damage your main UE4 install in any way,

If you get a crash dont panic, just read these steps again

" Help I can't Load UE4 Anymore "

The worst that can happen is that the config file gets setup up wrong,

and you wont be able to load the editor,

and it will crash if you try cause it can't find the new Engine class.

But, this is extremely easy to fix!

just comment out the line that you added in your config file and you are guaranteed good-to-go

Instanced Static Mesh Editor

Introduction Video

<youtube>https://www.youtube.com/watch?v=iC1sjgalEJg]</youtube>

Setup

<youtube>https://www.youtube.com/watch?v=mYj_kaLDZZ4]</youtube>

I recently added a feature so that you can select many static mesh actors that all have the same static mesh and convert them into 1 instanced static mesh!

This process can be reversed at any time to make individual edits!

In this way you can enable UE4 to render 1000s of static meshes while maintaining very high FPS!

Now you can edit instanced static meshes with all the tools you are familiar with and convert all the static mesh actors when you are done, to get a huge FPS boost!

Update: Part of Victory Ed Engine

My ISM Editor feature is now part of the Victory Ed Engine plugin which is separate from the Victory BP Library plugin :)

Mandatory Setup Step

To make my Instanced Static Mesh system work with your project you have to choose a ISM actor class. You can either create your own by adding a Instanced Static Mesh Actor to a new Actor blueprint, making the ISM component the root component, or you can use the VictoryISM class in my Victory BP Library plugin!

1. Go to Project Settings->Game->Victory Ed Engine

2. Choose your own custom Instanced Static Mesh Actor class, or use the one from my Victory BP Library plugin

3. Select a bunch of static mesh actors and press i to convert them, shift + i to convert back, also work with undo/redo

4. Enjoy!

Works With UE4 Undo System

My Vertex Snap Editor Mode now works with UE4's undo system!

Yay!

You can undo as many individual snap events as you want!

Note that I only save an undo state when you release the V key to avoid flooding the system while you are continuously snapping while holding down V.

So make sure you release the V key to save your final state before using CTRL + Z

Newest Editor Feature:

New Display Options

Now pressing the U key is a display toggle!

• Default = only show the vertex the mouse is hovering over
• Press U once to show all vertices
• Press U again to show no vertices
• Press U again to be back to showing cursor-highlighted vertices only
• etc

New Workflow(3/27/14)

• Press V to select a vertex
• Hold down V to continuously snap to vertices of other highlighted meshes
• Release to finalize the move

New Snap to Surface Normal Workflow

• Press V and and also hold down shift
• If you fiddle with your approach angle and move the mouse little bits, you can get some really great normal alignments without much effort

Enjoy!

Rama

Drop Static Meshes to Nearest Surface!

Now you can just press the Y key in the UE4 Editor

to drop the selected Static Mesh or Static Meshes to the nearest surface in the level!

You can drop Static Meshes down to each other too!

My algorithm takes into account the actual shape of the static mesh being dropped, as well as the landscape/level/meshes it is being dropped onto!

If you have multiple objects selected, they are treated as one big object and all the surfaces are calculated together, and the group is dropped, maintaining formation, to the nearest surface within your level.

Vertex Snap Plugin

My extended Editor Engine detects when the user clicks on a static mesh actor, and activates my Vertex Snapping Editor Mode.

UE4 Editor Plugin, No Code Compile Required

Dear Community,

This is my very first new Editor Mode for the main UE4 Editor!

This is a tiny ( under 10 MB ) plugin, that you can download and use without having to compile any source code.

Your project does not have to be a code-based project!

It adds 3 new features

1. Toggle instantly moving selected static meshes to the mouse cursor, to quickly move them around, or "teleport" them across the map, supports Multi Selection.

2. Press K to reset a static mesh actor's rotation

3. Vertex Snapping! Optionally snap to surface normal of destination static mesh

   -verticies can be resized anytime using + or -
   -you can cycle among 5 different verticies display options at any time 
   -you can toggle vertex displaying by pressing Y.

All of the features are related to static mesh actors and my editor mode disables itself if you are not working with a static mesh actor.

It is super easy to enable or disable my editor mode, or suspend it entirely after trying it out.

With my editor mode plugin you can enjoy some new features for your UE4 Editor Experience!

Victory Editor Align Mode

Features:

Instant Mouse Move of Static Mesh Actor

-Press T key to toggle this mode! (mapping it to a mouse button proved too complicated given all existing editor mouse button functionality)

-The selected Static Mesh(es) will move instantly to follow the mouse cursor anywhere in the XY plane, staying on the current Z

-This can be used to instantly move objects to a location by a. selecting them all b. moving to your desired destination location c. press T key and they will all warp to your current location :)

-Supports multi-selection

Reset any Static Mesh Actor's rotation to 0

-Press the K key -just a handy little feature, -extra-useful if the vertex Snap-By-Surface-Normal goes wonky

Vertx Display and Snapping

-Press Y key to toggle displaying of static mesh verticies! -Press B to toggled between five different display types for all verticies a. simple crosshair b. solid rectangle c. 3D box d. diamond (pretty good even at 4000 verticies) e. sphere (slow for > 3000 verticies)

-Hold SHIFT while selecting the second vertex to use Snap-By-Surface-Normal, which will try to align the source static mesh actor with the surface of the destination actor.

-snap selected static mesh actor by chosen vertex to the chosen vertex of another static mesh actor,

-can do whole process with 3 input key presses total!

Vertex Resizing

You can resize all the verticies at once by pressing and holding -/+

Verticies Dynamically Update

No matter how you scale or rotate the mesh the drawn verticies will update correctly:)

Vertex Selection

You can move/rotate the selected static mesh actor after selecting one of its verticies, and the selection will be maintained and updated.

WorkFlow Efficiency

Fast User Interface

Vertex snapping can be accompished in three input presses total

1. select the actor you are going to move 2. hover over chosen vertex and press V 3. hover over chosen vertex of other mesh and press V

The reason this only takes 3 inputs is because when you hover the mouse over other static mesh actors,

my editor mode automatically highlights all of the vertices and the vertex that is closest to the cursor.

Why not use Mouse Click?

The reason the vertex selections are key presses not mouse clicks:

-any kind of mouse click tends to change selection, and I dont wish to override this functionality

-it's easy to miss-click with the mouse on a vertex that is at a corner, and end up selecting the landscape instead

-the thematic consistency provided by using a same-key-press to do the whole snap process feels nice :)

The flow becomes:

hover mouse over vertex press key V

hover mouse over other vertex press same key V

Snap done!

Speed: Using the PDI / Primitive Draw Interface

In case you are curious, I am drawing directly to the PDI, the fundamental drawing surface, using DrawPoint.

This is about as light-weight as I know how to get at present

An advantage of using PDI and DrawPoint is that only verticies in the chosen depth priority will draw.

This enables me to hide verticies that you would not realistically want to click on from the opposite side of a mesh.

High Vertex Counts

-Verticies are not drawn if the object vertex count is too high (10,000 at moment), as that could cause a long delay or even a hang if you click on a high-res statue or something like that :)

- I automatically switch sphere vertex display mode down to box mode if vertex cound is > 5000 to prevent slowdown if cycling through the B key

Editor Environment Integration

-Victory Align Mode auto-activates when you click on Static Mesh Actors,

-Press P key to restore previous Editor mode and Real Time Status instantly

-Clicking on non-static mesh actors will restore previous Editor Mode

Example:

If you are busy clicking on stuff and you end up in my editor mode by accident, press the P key to instantly revert to prevous mode

Interface:

-There is a useful hover-button in top left of window that will show you all the hotkeys for this Editor Mode any time you hover mouse over it

-The hover-button fades itself out to be less visual distraction, but hovering mouse over it will fade it back in and display helpful info

-When using the Instant Mouse Move by tapping the T key,

     the move/rotate/scale main editor widget disappears to let you know you are in that mode and also because it is not really usable while using the T-key mode.

-Deselecting or exiting the mode cancels the Instant T(ranslate) key mode.

Using Vertex Snap Mode

Once you click on a static mesh actor, if the verticies are not showing, press the V key

1. Hover mouse on vertex,

2. press V

3. Hover mouse over other static mesh and one of its verticies,

4. press V

If you are using Align-By-Surface-Normal, the selected static mesh will attempt to orient itself to the surface closest to the vertex of the other static mesh.

Vertex Editor Plugin Summary

Light-Weight for Your UE4 Editing Experience

I tried to make the vertex-selection aspect of my editor mode as light-weight as possible,

- no traces - no collision - no extra actors involved - just drawing to the PDI

There is not actually any 3D collision for the verticies!

I defined a "button" struct which stores the projected coordinates of the verticies, plus the resizable drawn-vertex scaling.

So as you scale the verticies the buttons grow to accommodate.

Whenever the view changes, the buttons are freshed.

If there is no input to the UE4 Editor or you have it in the background, the buttons are never refreshed

In Summary, it's just a bunch of invisible floats that are determining when you are clicking or highlighting the verticies of the Static Mesh Actors

Have Fun

Have fun with my editor mode!

My Entire Plugin C++ Source Code

Credits

Feel free to use my C++ code as an outline for making your own Editor Mode Plugin!

Just please give me credit somewhere appropriate.

I did not use any algorithms or math equations from any source,

I wrote all the code myself and just used Epic's awesome UE4 Beta .h files as a reference.

 This code does not contain any UE4 C++ source code, as I did not have access to it when I wrote this plugin.

VictoryEdEngine

This is the class that becomes your new UE4 Engine class, and it must be set to be used by UE4 via DefaultEngine.ini

Core of Making Your Own Editor Mode

Interaction of EdEngine with EdMode Class

The key interaction between the Editor Mode class and the extended Unreal Engine class is in the Unreal Engine class, where it creates the editor mode instance.

Here is that code:

//Create it if it not exist yet
	if(!CreatedVictoryEdMode)
	{
		TSharedRef<class FVictoryEdAlignMode,ESPMode::Fast> VictoryEdMode = MakeShareable( new FVictoryEdAlignMode() );
 
		//Init VictoryEdMode
		VictoryEdMode->JoyInit(this);
 
		//Register
		GEditorModeTools().RegisterMode(VictoryEdMode);
 
		CreatedVictoryEdMode = true;
	}

Activating The Editor Mode, Once Created

Once you've created your own EdMode class instance, you activate your editor mode using:

//Activate Victory Editor Mode
GEditorModeTools().ActivateMode(VictoryEditorModeID);

The Ed Mode's Unique ID

Note that this is a const FName that I declared here:

const FName UVictoryEdEngine::VictoryEditorModeID = FName("VictoryEditorMode");

And you have to actually give your EdMode its ID in its class constructor. In my case I used my custom JoyInit function

//INIT
void FVictoryEdAlignMode::JoyInit(UVictoryEdEngine* EnginePtr)
{
	ID = FName("VictoryEditorMode");
}

Enjoy!

I hope that providing you with my entire Vertex Snapping C++ Source code helps you to create your own Editor Plugins!
