Render Warps
FumeFX supports various Space Warps that can affect FumeFX at render time. This tool gives artists lots of flexibility for post-simulation adjustments. Because Space Warps can significantly distort FumeFX volume, supersampling is used to lessen the effect of artifacts.
Supersample Min – Minimum number of samples.
Supersample Max – Maximum number of samples.
Auto Scale Density – Rendering output can be affected due to the volume change caused by Space Warp distortion. This option can keep similar rendering output when Render Warps are used.
Viewport Degrade – Because Render Warps require lots of computational power, you might want to use lower quality for Viewport.
