Finally afforded the upgrade and installed 3.08.00.39 plugin with the 3_07 standalone.
Projects I created with Version 2 are rendering significantly different with Version 3. It looks like the Specularity is unevenly applied or just a bug of some sort.
I checked the update notes and noticed there was a similar report of a smoothing bug for mixed materials. The problem with my projects looks very similar with an unpredictable luma fall-off that could be related to shadow rendering.
Is there a compatibility mode or a parameter or a known work around?
I tried backing down to 3.03.03.20 with 3.03.03 and that fixed it.
Latest: For anyeone else who sees this issue- got it working all the way up to 3.06.04.35 with the 3.0.7 standalone.
Excellent work on the seamless integration, Sighman! Having octane as an option in the renderer drop down... very nice!
If there is a way to use the latest version with Carrara files created with V2, it would be nice to have a solution or work-around.
Thanks!
