Arnold 4.1.x has plenty of new features and improvements, and you can read about those in the release notes.
Here’s a few other little things to know about Arnold 4.1.x:
- All shaders, procedurals, and plug-ins like SItoA and MtoA need to be recompiled to work with Arnold 4.1.x.
- You need a new license to render with Arnold 4.1.x. An Arnold 400 license won’t work with Arnold 4.1.x.
- Ass files written by Arnold 4.1.x cannot be loaded by older versions of Arnold.
