I just upgraded to 3.18.X from 3.17.x Max 2012 x64 SBM now exports with a different offset to any OBJs I export from either zbrush or max. If I import the SBM back into max it is rotated 90 degrees and the translation on the Y axis is flipped> ie instead of +33 it is -33. Or so I gather from eyeballing it briefly. So pics…
think about how dilation works, it cannot get accelerated much at all. For each pixel you must check if one of the neighbors (4 or 8) was set and then copy its value. In the 2k x 2k texture map thats like 33 million lookups. One could try to do it on the GPU, by using the stencil buffer and offset the image by one pixel,…
