Python Callbacks inside an asset in Engine June 29, 2015, 3:58 p.m.

Upon further investigation my python exporter did in fact work. I tested the script on a set of static points and it worked fine. There appears to be an issue with directly reading points from non-file-cached dop sim. For some reason, writing the points to disk (geo rop) and reading them back in before running the export script made it work.

It's particularly bizarre since the sim scrubs properly in maya no problem from memory. This only happens on cooking a branched node chain.

I can try to isolate and reproduce the issue, if it's indeed a bug ill make an RFE

Python Callbacks inside an asset in Engine June 26, 2015, 5:03 p.m.

I have an asset that takes some inputs and runs a bullet simulation to generate contact data. This point data needs to then be exported to a plain text file for other purposes. Currently I have a python sop with a button that, when pressed, runs a callback function to read the input geo and format it to a file. This works fine within houdini but upon trying to run my export callback from engine in maya it appears to output nothing, as in theres nothing being returned from ‘pts = hou.pwd().geometry().points()’

I'm not sure how something like this is evaluated in the Engine context, could someone explain what the best way to do this is?

Did you convert your geometry to tetrahedra?
