Question by NY55 · Sep 15, 2021 at 02:49 AM · shaderparticlesparticlesystemshader writing

ParticleSystem Transform Scale × Shader UV Tiling

Hello.
I created a shader that changes the UV tiling based on size.
Quad works fine.
It doesn't work with ParticleSystem.
What should I do?


 float3 recipObjScale = float3( length(unity_WorldToObject[0].xyz), length(unity_WorldToObject[1].xyz), length(unity_WorldToObject[2].xyz) );
 float3 objScale = 1.0/recipObjScale;
 
  fixed2 Multiply = (i.texcoord*objScale.rb);

Answer by NY55 · Sep 15, 2021 at 03:49 AM

I was able to change the UV tiling by receiving the particle size from the texcoord.
However, what I would like is to receive the particle's Transform Scale.
Is there any way to do this?
