Dear Friends of 3DE,

well, it's a bit embarrassing, but we actually managed to fuck up the stabilizer models of b12 once again. So, here is the 3rd iteration of these new distortion models (3DE4 R8.0 beta14). They should behave much better if combined with extreme (degree 2/4/6) distortion values. Hopefully, everything is working fine now - I'm sorry for the trouble...

To make confusion even worse, there is also a new LDPK. If you're using Nuke, please make sure to use 3DE4 R8.0b14 only in connection with the nodes of LDPK 2.12.0!

Cheers, Rolf
