How to use a texture atlas with particle trails?

Hi there. I am currently optimizing all my particle effects to use a single texture sheet only. Works great so far using the "Texture Sheet Animation" module of the particle systems. However, this only sets the texture of the particle itself, not the particle trail.

I couldn't find a way to also use a texture sheet for the particle trails yet. Am I missing something?

 

I was just having a very very quick stab at this. I'm not expecting to find a solution (and haven't searched for solutions as yet) but quickly knocked up a flipbook shader in Shader Graph just to see if I could figure out a way of doing this.

The bit where I think I'll run into trouble is figuring out how to sync the flipbook to play with the trails correctly (off-hand I can't think of a way to do this).

It would be lovely if trail materials could have an option to inherit [or have their own] texture sheet animation settings.

It's something that would be an incredibly useful feature (although, quite likely, a far from simple to implement).

 

I'm having the same trouble and because of this I'll have to copy materials for each trail with different sprites. Was trying to find a way to integrate flipbook node with current sprite assigned to texture sheet module but didn't get anywhere. If Unity could make everything that's applicable to particles work on trail particles too, we all would save a lot of time and performance cost. Do you think this'll be available any time soon?

 

mobile devs could still benefit from it, so i dont see why not support it... also is it possible to modify the system myself?

 

and how do we write our own modules? I googled everything and no one seems to do it

 

so using this we could do anything? like texture sheet and vertex streams for trails etc?
