AI Navigation ~ Move To With Filter, Create Custom Pathing Using Nav Modifiers

Dear Community,

I’ve created a video and a sample BP-Only project (+ my Victory Plugin) that shows you how to use Nav Modifier Volumes and Navigation Query Filters to create custom pathing for your units!

**Use Case: Electric Currents and 2 Types of Characters**

In my example, I have two types of units.

The **blue unit** is immune to electricity, and does not need to path around electric currents.

The **red unit** bids us all a fond farewell if it passes thruogh an electric current.

So in this case I can't just block of areas that have electric currents completely from the nav mesh, or else the blue unit cannot pass through freely as it should be able to, taking a shortcut as a result.

**This is a case where Nav Modifiers and Query Filters really shine!**

I only want to **filter out** certain sections of the nav mesh for the red unit, while still allowing the blue unit to pass through those areas freely.

Custom BP Node

In order to actually be able to use query filters and nav modifiers in a BP only project effectively, I made a custom BP node, AI Move To With Filter.

This node allows me to tell the unit to move to a certain location, while using a query filter, only in Blueprints!

**Changes Nav Behavior Filters  ~ Per Move ~  If You Want To!**

Using my Victory BP Library node, you can actually have a unit changes its navigation filter per move if you want to!

This enables you to have the AI respond to dynamic level conditions (like if the electricity in my example gets turned off), or if you just want the AI to confuse the player by randomly switching its pathing preferences!

Very useful! Thanks a lot for sharing, Rama!

Hi Rama,

This is really awesome!!! Thank you so much for this updated plugin. I can now propagate fire to skeletal meshes and characters.

I am gonna try incorporate this into my current propagation script.


Hey Rama,

I noticed minor mistake while using your rotation/vector conversion nodes:
The tooltips say opposite of what they do!

Edit: Also I just found out that there’s a node called RotationFromXVector that does the same thing, but yours is named a lot more clearly/easier to understand.

Yay! Great to hear from you Jacky!

Ahh thanks for pointing that out, I’ve fixed the comments in my local version, and it will be in my next update!


You’re welcome, I hope my animated vertices of skeletal meshes BP node takes your thesis research to the next level!



Get a Float as a String, With Precision and Optional Leading 0 !


Dear Community,

I’ve updated my Get Float As String With Precision node to

  1. Be pure (no exec chain)

  2. Utilize Epic’s FText C++ code to leverage all of their hard work on float decimal precision.

  3. Add bool to make the leading 0 optional, so 0.5 could be shown as 0.5 or .5 depending on your preferences!


**My C++ Code For You!**

Here's how it works in C++ !


void UVictoryBPFunctionLibrary::StringConversion__GetFloatAsStringWithPrecision(float TheFloat, FString & FloatString, uint8 Precision, bool IncludeLeadingZero)
	FNumberFormattingOptions NumberFormat;					//Text.h
	NumberFormat.MinimumIntegralDigits = **(IncludeLeadingZero) ? 1 : 0;**
	NumberFormat.MaximumIntegralDigits = 10000;
	NumberFormat.MinimumFractionalDigits = **Precision;**
	NumberFormat.MaximumFractionalDigits = **Precision; **
	FloatString = FText::AsNumber(**TheFloat**, &NumberFormat).ToString();

Ragarding the ability to save the Color Array to a Texture2D:

Have you get anything to work?

you have deleted the victory rebind key ? with the new plugin i have error about that*
btw awesome plugin
you are a time saver

Hi Rama,

This plugin is awesome! Very handy thank you.

I am having an issue with the Capture Component 2d Save Image node. It works well when I play in editor, however when it is packaged into an exe, the game crashes whenever I trigger the save image node. (See image attached)

Is this a known issue?

ok, i figured out how do it.**

Rama Key Rebinding During Runtime System

I have a 4.8 updated version of my Key Rebinding project here, which now includes axis bindings!

[Full Project] Rama's UMG Rebindable Key System, Rebind keys at Runtime! - Community Content, Tools and Tutorials - Unreal Engine Forums!

My Victory BP Plugin has the new and updated nodes I use in the project



Capture Component 2D ~ Save Image ~ Crashing in Packaged Games

Yes this is a known issue, I did not develop that particular node, I am forwarding your report and hopefully it will get resolved!



**Load Texture 2D From File!

JPG, PNG, BMP, ICO, EXR, and ICNS are Supported File Formats !**

With this node you can load a Texture 2D from a file during runtime!

I output for you the width and height of the loaded image!

Now you can easily create Texture 2D’s from image files in Blueprints, during runtime!

Special Note!

Tim Sweeney liked this node!



PS: Make sure to include the file extension when you use this node!


**C++ Code For You**

Here is the core C++ function involved, entire source is in the download! I wrote my own Enum for the file formats.


UTexture2D* UVictoryBPFunctionLibrary::Victory_LoadTexture2D_FromFile(const FString& FullFilePath,EJoyImageFormats ImageFormat, bool& IsValid,int32& Width, int32& Height)
	IsValid = false;
	UTexture2D* LoadedT2D = NULL;
	IImageWrapperModule& ImageWrapperModule = FModuleManager::LoadModuleChecked<IImageWrapperModule>(FName("ImageWrapper"));
	IImageWrapperPtr ImageWrapper = ImageWrapperModule.CreateImageWrapper(GetJoyImageFormat(ImageFormat));
	//Load From File
	TArray<uint8> RawFileData;
	if (!FFileHelper::LoadFileToArray(RawFileData, * FullFilePath)) 
		return NULL;
	//Create T2D!
	if (ImageWrapper.IsValid() && ImageWrapper->SetCompressed(RawFileData.GetData(), RawFileData.Num()))
		const TArray<uint8>* UncompressedBGRA = NULL;
		if (ImageWrapper->GetRaw(ERGBFormat::BGRA, 8, UncompressedBGRA))
			LoadedT2D = UTexture2D::CreateTransient(ImageWrapper->GetWidth(), ImageWrapper->GetHeight(), PF_B8G8R8A8);
			if (!LoadedT2D) 
				return NULL;
			Width = ImageWrapper->GetWidth();
			Height = ImageWrapper->GetHeight();
			void* TextureData = LoadedT2D->PlatformData->Mips[0].BulkData.Lock(LOCK_READ_WRITE);
			FMemory::Memcpy(TextureData, UncompressedBGRA->GetData(), UncompressedBGRA->Num());

	// Success!
	IsValid = true;
	return LoadedT2D;

Hey Rama, what’s new about the node? You have already posted it here: (39) Rama's Extra Blueprint Nodes for You as a Plugin, No C++ Required! - Blueprint Visual Scripting - Unreal Engine Forums Your last post seems to be the exact same one, I’m just a bit confused :confused:

It’s not that there’s anything new, if there is I will tell you, I repost nodes periodically for newcomers and as reminders for people who’ve not tried certain nodes yet.

I also do this to recenter the thread on its focus of being a whole bunch of extra BP nodes that I am giving to the Community to play with!

I hope you are having fun today!



Sound Classes SFX/Music Separate Sliders

Thanks again for the “Victory Sound Volume Change” and “Victory Get Sound Volume” class blueprint, helped so much. Best part about it, I didn’t even have to create save object files for the setting. It automatically saves the volume for you.

I even made a short tutorial on how to use it.

I thought this was going to be more complicated but realized it was really easy to set up.


Old code :slight_smile:
Fix incoming soon’ish.
New code is directly from released versions of Ground Branch, which has been packaged into an exe multiple times.
Stay tuned :slight_smile:

**Improved Get Vertex Locations of Static Mesh

Now works in Packaged Games**


My C++ Code For You

See my PhysX wiki for the basic build.cs setup:

Here is the code I wrote to get all of the transformed vertex positions using the Body Instance and PhysX code!

I am doing many safety checks to ensure the Body Instance data is valid before utilizing it, and the result is that now you can get accurate vertex locations in packaged games!

//~~~ PhysX ~~~
#include "PhysXIncludes.h"
#include "PhysicsPublic.h"		//For the ptou conversions

//Get Transformed Vertex positions of any static mesh! -Rama
bool UVictoryBPFunctionLibrary::GetStaticMeshVertexLocations(UStaticMeshComponent* Comp, TArray<FVector>& VertexPositions)
	if(!Comp || !Comp->IsValidLowLevel()) 
		return false;
	//Component Transform
	FTransform RV_Transform = Comp->GetComponentTransform(); 
	//Body Setup valid?
	UBodySetup* BodySetup = Comp->GetBodySetup();
	if(!BodySetup || !BodySetup->IsValidLowLevel())
		return false;
	//Get the Px Mesh!
	PxTriangleMesh* TriMesh = BodySetup->TriMesh;
		return false;
	//Number of vertices
	PxU32 VertexCount 			= TriMesh->getNbVertices();
	//Vertex array
	const PxVec3* Vertices 	= TriMesh->getVertices();
	//For each vertex, transform the position to match the component Transform 
	for(PxU32 v = 0; v < VertexCount; v++)
	return true;

Can someone tell me how “Create Texture Render Target 2D” works correctly? I try to use it to create icons of meshes that have up to three different, user-chosen colors (so I can’t use simple textures and tint them). I do it in front of a pink (255,0,255) screen and set up the clear color to match the color of the screen but the output looks like this:


The greenish color is the button behind the image.

It’s supposed to look like this:


Minus the pink color.

Hello all,

I am trying to convert a group of spawned static meshes into an Instanced Static Mesh, and then Spawn multiple copies of that ISM, using blueprints. the “Victory ISM Convert to Victory ISM Actors” Node works great, but I can’t for the life of me figure out the 2nd part which is spawning multiple copy’s of that created ISMActor into the level. Can someone please give me some tips on this blueprint setup? Which nodes do I need to use to Spawn that Victory ISMActor properly?
