I have a simple box which I am using to create a velocity volume. But as you can see in pic below, output looks strange. According to docs, it should create velocity volume with constant value {0,0,1} set for all voxels, however I am seeing this strange edges. Is it a graphic card issue or am I missing something?




Another issue is, when I place a vertical grid inside volume and use velocity trail sop, I expected that all trails should be of same color since I have set the velocity values as {0,0,1} for all voxels, but why I am seeing this gradient which clearly indicates velocity values near edges are less than 1 ?
