Here is the reaction diffusion stuff. I have not done any housecleaning whatsoever in this file so it is just a bunch of unrelated crap in COPS. you might like what you find.

…and so I wrote my own geo rasterizer to be able to bridge texture seams by generating a lookup UV map. Really pain in the assy stuff. But now I can generate the rain streaks without any visible texture seams at all. So that’s a significant win!
I will use this kind of rasterizer a lot.

you basically generate a adjacency uv map like this.

any tricks to choose which cameras to hide from here ?

of course the info is clear as hell on the docs and I can’t read for some reason 🤦‍♂️ `To prevent cameras from appearing in the viewport menu, add a spare parameter named viewmenu to the camera you want to hide and change the value to 0`

@tokyomegaplex Sry for the delay, but here’s a simple scene that will hopefully give you an idea of how to do your hair stuff in SOP vs. OBJ context. Re deformation of the final groom, it’s always tricky (every presentation I watched pretty much ends with “yeah, we wrote our own hair deformer”), but with enough fiddling you can get acceptable results. There are notes all over the place but if something is not clear, just let me know. *I’m prepared to be ridiculed by the folks who do this type of stuff on a daily basis, just so you know :)*
