Performance Question regarding Skinned Geo Animation Nov. 7, 2024, 12:12 p.m.

I will give that a try, and thank you for the general tip as well Tanto!

Performance Question regarding Skinned Geo Animation Nov. 7, 2024, 10:56 a.m.

Hey everybody,

If I have some input geo with a skeleton, and then I procedurally add a bunch of things to it (shells, greebles, etc), should I apply the animation before the new geo is created, or after?

Basically Geo A1 has 1,000 vertices and I animate these, and then later in the chain it's Geo A2, animated and with 10,000 vertices. Or geo A1 has 10,000 vertices before it's animated.

In general, is there a handy way to measure the performance of things like this in Houdini?

Regards,
slh

Shell Texturing with Alpha from Geometry Oct. 25, 2024, 2:39 a.m.

For those interested, I got an answer on Discord:

USD has different names for common attributes
Cd is called displayColor, for example
i believe Alpha is displayOpacity
without the '@'

So using `displayOpacity` as the value in `Geomprop` allowed the material to use the correct opacity value, whereas Alpha, which didn't exist in the context, must have defaulted to 0.
