I've being using Autodesk Combusion for nearly six years but I still have a major problem that couldn't get over.
The issue is, when I import footages of volumatric effects (smoke, fire, plumes, clouds, trails) done in maya or 3dsmax, It appears to be having a thick black edge around the volume effects. Even if it's under premultiplied mode.
I basically tried srinking one pixel but it looses image detail. this problem applies to combustion particles too.
just for an experiment when I import them to After effects, it does a great job and gets rid of black edges while it retains detail.
Please let know a solution to solve this major issue.
