Title: MAXScript Rollout Handler Exception-unknown property: brdf_useRoughness VRayMtl
Post by: sailor on 2021-07-23, 15:04:01

Hello,

I installed Corona 7 on Max2015 today and tried converting Vray2SidedMtl using Corona Converter 2.0 but get that error. How can I solve this issue?

Which version of V-Ray are you using? You need V-Ray 4 or newer.
The error message is indeed confusing and we will improve it.

The VRay version is 3.20.02, I thought the version number doesn't matter cuz heard it works even the license has expired.

I couldn't type the entire error message in the Subject text box, guess hit the limit so shortened it.

License can be expired, but the version can't be ;) At least, not beyond a certain point.

You only need to have V-Ray installed. You do not have to worry about the license.
