I want my particles to have a glow to them so they appear hot/bright, but i can’t use the texture for the glow because my particles are very small and then that makes the glow very small with it so i need the glow to be separate to the actual particle texture so i have more control over the glow size.
How would i do this ?
Can you use post effects / bloom?
Won’t that affect the whole scene rather than just my particles?
Yeah, but you can control bloom and what is effected by it with bloom settings, you could just make the particles a bit more emissive than anything else and set bloom up so that it’s only effecting them. The other bonus is other things in your can can then also get a similar effect if you want.
It might be a bit overkill if you only want it for the particles, but the only other way i can think of is to use bigger particles with a texture that has a ‘glow’ in the texture.
Is there no way to have 2 textures on the same particle so i can control the glow texture around the particle texture? That way i can then also scale each texture so they are independent of each other ?
you might be able to program another emitter and set it’s particles in code to follow the other emitter’s particle positions.
if you are using lit particles, you can enable Use Emissive Map in the inspector after selecting the output:
Alternatively, you can make a VFX Shader graph with the desired textures you want and control your emissiveness.
