19.5 skeleton blend not working like before Aug. 10, 2022, 2:19 a.m.


Following a tutorial by Kamil Hepner and the skeleton blend in 19.5 doesnt work like before.

I have deleted joints to make controls, used attachjointGeo with some circle splines as control shapes and used a rigpose node so i can animate pos and rotation. Added the skeletonblend node to mix the movement and nothing happens. In previous versions it worked fine so not sure what is new. Tried adjusting the weight value and world space toggle but no joy.

Is it a bug? Or just a new way to do things..

Anyone have any ideas?



Redshift ramp without UV Dec. 23, 2021, 8:51 p.m.


Using Redshift to render and wanted to use a RSRamp node but it only seems to work with UVs which my model doesnt have as its a large scan.

Other Nodes like the noise nodes create without needing UVS. Is there a way to use maybe the rest attribute?

As a work around I created a attribute wrangle and mapped Cd to the bounding box of the mesh. I brought this into Redshift using the color user data node, means I have to go out of the material network to alter that ramp which isnt so handy.

Can anyone advise on a better way? I suck when it comes to rendering so thats why currently trying to level up.

Many thanks

Scaling vellum objects so they start small and end big July 9, 2021, 6:52 a.m.


I have a sim where vellum tetrahedral objects are brought in via the instance points emission type.

They are supposed to come from a small space at the start so I wanted to scale them from 0.1 of their size up to full size after a few frames.

Is there a way to scale vellum objects like during the sim or would you scale them after doing the sim?

I can make a simpler version of the scene if needed.

kind regards,
