[Question] how to increase patch buffer size

[taochenshh]

Hi, thanks for the great library. I am using Orbit (devel branch) to run 4000 environments in parallel, and I got the following error:

2023-12-19 20:04:05 [5,983,110ms] [Error] [omni.physx.plugin] PhysX error: Patch buffer overflow detected, please increase its size to at least 219146 in the scene desc!

Which parameter can I tune to increase this buffer size? Thanks.

Hi, you can modify the allocated GPU buffers through the setting here:

Hi, @Mayankm96 I'm also stuck with the same buffer error as @taochenshh . It seems that the URL you provided for the solution doesn't exist. Could you provide me with the latest information?
