I stashed the low version of Disney cloud (I use the full one for the test -> solaris), and the grid too so you see at least something in Hou. I don’t know much about properly link karma render to copernic so yeah I just saved the 2 render files. Don’t judge the opencl code, it’s build with chatgpt. Beside you can probably render the effect directly in cop, but again no clue how import a point position, so I solve it in vex. Feel free to correct my crap :O)

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`
