3dsmax Space to Houdini Space Sept. 4, 2019, 2:06 p.m.

Geometry inputs will now have 3 new detail attributes attached – hemax_quaternion, hemax_transform_world, and hemax_transform_local.

hemax_quaternion: this is the rotation (in Houdini's coordinate system) before it gets converted to Euler angles and placed in hemax_rotation.

hemax_transform_world: This is the raw world space transformation matrix of the 3ds Max node.

hemax_transform_local: This is the raw local space transformation matrix of the 3ds Max node.

This will be available in tomorrow's daily build.

Issue with HDA Processors not updating Sept. 3, 2019, 4:52 p.m.

I would check your “Cache Mode” setting on HDA Processor. If it's set to ‘Automatic’, it will look for its output file on disk and if it already exists, the work item will be marked as cooked (therefore skipping the job execution).

Are you able to attach a .hip file?

3dsmax Space to Houdini Space Aug. 30, 2019, 3:22 p.m.

The rotation values aren't as straightforward because the plugin converts the 3ds Max quaternion into Houdini's coordinate system and then converts it to Euler angles.

Would it help if it also attached the raw 3ds Max quaternion as a detail attribute? Something like hemax_quaternion. Then I believe you should be able to use the conversion in my previous post to create a quaternion in Houdini and also be able to convert it to Euler angles.
