Bone pre_xform python Aug. 8, 2018, 11:05 a.m.

Hello,

I think you're probably looking for bone.moveParmRotateIntoPreTransform(). Or you can use bone.setPreTransform(some_Matrix4)

.ds File Spec June 20, 2018, 5:45 a.m.

Ah! Thanks Koen,

I had a feeling there was something like this lurking around. Unfortunately, I believe it's an option only available to those with a full commercial license.

Would still be great to have the spec written out somewhere for reference

.ds File Spec June 19, 2018, 6:34 a.m.

Hi Daryl,

There doesn't appear to be a defacto spec written down anywhere I can find, hopefully there'll be some soon! The best sources for this information at present appear to be the wonderful SOP_WindingNumber project in the $HFS/toolkit/samples/SOP folder.

The DS file starts on line 390 of SOP_WindingNumber.C and includes examples of many parameter types, the other place to look is possibly $HFS/houdini/python2.7libs/generate_proto.py which actually parses the .ds file - the dsparm() function at line 1487 is worth a gander at.

Not the cleanest set of docs on the topic, but make for interesting reading anyway. Hope that's useful

Cheers,
Henry
