Hi
i have large curved surface i want to emit from , issue i get is stepping from the grid voxels

im only emitting for 10-15 frames, any technique to eradicate/minimise apart from jacking the grid resolution way high?

cheers

Hey, the emission will be in the shape of the voxelized surface indeed.

You can smooth it out at render time with opacity mapped by a distance texture using the distance to the emitting geometry like in this tutorial: https://phoenixfd.cgrecord.net/2019/04/making-of-burning-motorcycle.html

Hope this helps, cheers!
