Glossiness/Roughness slider doesn't work if "use roughness" gets ticked

In the new update 7.00.04 the roughness/glossiness slider stops working if you tick “use roughness”. Doesn’t work either if you tick it off. You will have to create a new material to get it working again. and then the same bug happens again if you tick on/off.

Can anybody reproduce this?

No issues here. You have set a non-black reflection color, right? If the issue persists, send a video or scene.

It may have been a bug. Installed it again and it works fine now. Thank you

I have same issue. Can’t fix when reinstall.

I also have issues with this bug again. Please fix it asap

I still can’t reproduce it. There must be something else in the shader causing it, since it doesn’t seem to happen on a default material with white reflection. Could you try to reproduce it on a simple scene?

I get this error when enabling roughness

// Error: Unable to resolve attribute ‘VRayMtl.uro’. Make sure specified attributes are valid.

Hi @Twist

Are you using CPU or GPU ?

Best,

CPU, but I get this error just when enabling it. Not during rendering

Okay. Turns out we already have this issue logged (internal tracker ID: VMAYA-13463). Work has already begun on a fix.

Fixed in the latest update 1.

Thank you.
