Matching the usd version and the arnold version for the usdproc custom build

[it8GY2P]

Hi,



We are trying to build custom usdproc. And to do this, we need to understand which version of the usd core we should use. Is there somewhere a description of the version correspondence between the arnold core and the usd core. I would also like to know what additional libraries you are building for usdproc (oiio, ptex, alembic, vdb, etc.). For example, now we want to build our usdproc for the Arnold 6.2.1.0. Apparently we are using a newer version - there is a difference in the scheme, which is why dome light does not illuminate correctly if hdri is used.



Thanks!

From the Arnold release notes, here's the USD versions:

• 7.0.0.0 USD 21.08
• 6.2.0.0 USD 20.11
• 6.0.2.0 USD 19.05

We don't build OIIO and those other libraries for USD. We build them for the Arnold core renderer.
The USD procedural is just USD.
