Originally posted by Grooveholmes I once heard someone say to expand your subd nodes in the hypershade and delete the blind data nodes. Apparently its supposed to speed up the process esp. in poly proxy mode. Mind you, i don't really know what the hell deleting those nodes does or if it will cause problems down the line. On the few occasions that i've tried this i have noticed a significant performance improvement. expand subd nodes? delete blind data? can you possibly explain that in more detail? and is it possible to work on the poly proxy w/o the constant updates on the subd level?
