Niagara Mesh Renderer Sub UV

KZz80 · September 10, 2021, 5:12am

Hi!

There is an option for Sub Image Size for Niagara Mesh Renderer too but it doesn’t work. The Feature
works fine in sprite renderer but it doesn’t in mesh renderer.
Can anyone help me?
4.26 engine version

Hi there!
Did you even got an answer? I’m looking for the same thing!

I recently encountered this thread while looking into the same issue. here’s what I found out.

The texture Sampler in the Material needs to be TextureSamplerParameterSubUV rather then the normal TextureSamplerParameter2D

The SubUV animation setup then is the same as for a sprite.

the node looks exactly the same as a normal TextureParameter2D

you can also use the ParticleSubUV with a TextureObjectParameter

Hey, I figured it out!

You need to add a “Particle SubUV Properties” node to the Texture Sampler. I think it passes the Sub UV data from Niagara to the material. But when using sprites, you don’t need this node in the material.

Unreal Engine, weird huh?
