The triplanar filter in SD5 will use the pixel processor node and will probably have the same features. I can't promise the performances will be a lot better as this is the very first version of this node. Their is room for a lot of improvements in the following 5.x updates.
The tri planar node is awesome. Now that SD5 has been announced and advertises its own tri planar node, care to share how this one stacks up? About the same functionality wise but I imagine a lot faster?
