Doubts about instancing with geo node + texture particle

Beginners
1

quick doubt here,
Im doing instancing of particles with a geo node

  • as input to the geo node I have an sphere SOP
  • therefore I got lots of sphere particles
  • If instead of having a sphere SOP as the particle I wanted to have an image texture how would I do that? because I try to connect an image top or imagemoviefile top to the geo node and its not allowed, it only lets me connect a SOP

thank you :slight_smile:

You need to use texture instancing. There is some tutos about it.

thank you @jacqueshoepffner Im gonna check these ones to see if they help me understand it

@jacqueshoepffner but this here is talking about setting the coordinates x,y,z using a texture which I am already doing, Im already doing that; what I want is to replace the actual particle with a texture

I see I think this one is referring more to what I need:

You cannot replace a particle with a texture… You can replace the particle with a sop geometry with some uv mapping, the affecting some material with texture (as Constant Map) to the geometry Comp and finaly use texture instancing to affect a different texture for each instance.

@jacqueshoepffner thank you very much, I see, so the particle always has to be a 3d geometric shape, but I can map a texture on top of it, yes that would be also ok, and same texture to all of them would be ok for me

now, I understand this is for instancing, because if Im doing a particle system directly in GLSL with a pixel shader then I can use textures as particles if I remember correctly
