Turbulence FD Emitter Diagonal Banding

Recommended Posts

Can't seem to figure out how to get a more organic fuel emission on the card object. I tried breaking up the geometry, but the flames still seem to flow along a uniform diagonal pattern. Does anybody know what I'm missing?

Thanks!

I tried decreasing voxel size, using volume texture, using surface texture, increasing fuel diffusion, increasing fuel mask smoothing, increasing turbulence, still getting the banding...

Tried subdividing the mesh, I got volume texture and 'Use Vertex Map' to work, but still getting that diagonal banding. I'm using the latest version (v1.0 rev 1435). Tried posting on Jawset's forum, but still waiting for approval. I should also mention that sup-frame steps is up to 3 on all these tests...

Ok, think I figured it out. Had to turn up smoothing for the shaders. It wipes out a lot of thinner detail so you have to increase the fuel rate to thicken up the burn. Then you add detail back in using sub-grid detail:

I'm actually re-opening this, I've been working with the smooth setting for the fire shader and adding sub-grid detail, it looks like the banding is still showing up at certain points of low density and movement.
