point cloud .pc vs .bgeo Feb. 15, 2025, 1:13 p.m.

In performance terms, for lookup with VEX (pcopen, etc.), is there any practical difference these days between storing points as .pc files or .bgeo?

For .bgeo, does ordered vs. unordered matter?

Solaris Portal Lights? Dec. 26, 2024, 10:34 p.m.

I just tried portal lighting for the first time in 20.5.

It looks like there is different behavior between XPU and CPU.

In XPU, the original dome lights remain visible. In CPU, they are turned off.

Is this expected?

retiming value clips Dec. 16, 2024, 11:21 p.m.

Also somewhat related to this, is there a way to cache time samples on only *specific* prims, rather than the entire stage?

The scenario I have is that I am using the timeshift LOP on a particular prim, but there are no parameters to re-calculate the full frame range so I end up with a time dependency in the node graph. If I attempt a cache node afterwards, any value clips are cached in full per-frame which I don't want.
