My sprites are now rendering fine, thanks for the help. I have split my particles in POPs into groups, ie when they are hit. I want to have different shaders on the groups. I thought that using the shop SOP and referencing the groups would work but it didnt, i think because it is looking for SOP groups. What I need is a POP shop. Is there such a thing? Thanks for any help

The groups created in POPs should translate naturally as point groups in the SOPs world, so what you're attempting to do should work. Is the shader SOP giving you an error message? When you MMB on the node to get the info, does it list the point groups?

….ive got it working with a pop SOP going into a shop SOP, and when i mmb it, i can see the point groups, but now my particles are not doing what they were doing before.. They seem to be going off at the wrong tangents…I might have to play with the groups a bit to get it working. Thanks so far
