meta loop VOPs

Coolio. No problem. I thought the transform was a bit weird, too, which is why it stuck in my mind when you asked. I still say that the order of VOps which are ambiguously ordered in network mode should write VEx code according to their relative positions in List mode (as apposed to having to use input logic to enforce code ordering). I believe this is an RFE. In the meantime, I debug principally by dumping and inspecting VEx code, printing lost of stuff out, and... well, dumping and inspecting VEx code. ;-) Glad it helped. VOps have transformed my custom development in Houdini. -caleb Sean Feeley wrote:
Rock on! It turns out I wasn't transforming the points. Using a space change VOP and going from World to Object space (seems backwards, but oh well) did the trick, as did putting the metanext into a subnet to force execution order.
