Hi @tim1
Sorry, didn’t notice that. Basically, PT does increase the load of D5 files since it calculates more light compared to ray tracing. If it does get removed in future updates, I think there will be another option similar to this one.

I am encountering an unexpected issue with path tracing.
I recently disabled path tracing for a specific animation project. However, when I opened a different file the next day, it appears that path tracing remained disabled. The expectation is that the software should revert to its default (enabled) setting for new or different files.
Could you please advise why the path tracing setting is not reverting to the default state and how I can ensure it is enabled by default across all projects?
