Extracting KineFX transform matrix to OBJ-Level Oct. 10, 2022, 5:47 a.m.

thx a lot.
yes rivet seems to be an option, but i also need scaling, which seems not possible with rivet. or is there another trick to extract also scaling?

Have you packed your geo before copy to points or while? That would improve performance significantly.
i tried packed, but no really performance gain. the copy to points acts in my case more like a contrainer and not an instancer...
the objects being transformed to the points are all unique...
(also i need them unpacked at obj-level because using redshift and need its obj tags for shading...)

Extracting KineFX transform matrix to OBJ-Level Oct. 9, 2022, 5:51 a.m.


i have an fbx animation coming from maya and using kinefx fbx-anim-import to load it to houdini.
the imported points have also a "transform" (translate, rotate, scale) 3x3 matrix attribute.
i have to constraint some heavy assets to this points, so my first intension was to use copy to points in conjunction with the name attribute from the points.
works well, all transforms are coming through, but its very very slow when scrubbing the timeline.
constraining the assets on obj-level would be more effective, but how to extract the tranform matrix from the fbx-import-node at sop-level to the TRS of a geometry-node?
is there an expression or something else to use the matrix directly?
any hints are welcome

Material builder - create copy reference cut/paste Sept. 25, 2022, 5:56 a.m.


i have a bunch of material builders.
i want to share a material by "create reference copy" from one of the builders and copy-paste them to other builders, so i can adjust them with only one "master".
but it doesnt seem to work, as soon they are pasted to other builders, the referenced channels doesnt update to the pasted builder paths...
is there something i miss with creating referenced copies on materials (inside a builder)? or is there a build-in command i can use to change the channel paths, so they point to the right location?
