When using a VRay2SidedMtl, sometimes when loading a scene the “Multiply by front diffuse” is unchecked even though it was checked when scene was saved.
How often does it happen?
Does it happen on every or just on particular one?
What are the V-Ray and 3dsMax version that you are using and how we can replicate that into our environment?
How often? About every 4th or 5th time I guess.
It happens in all scenes using VRay2SidedMtl.
It has been happening for me on max versions back from 2015 up until 2017 (I haven’t updated to 2018 yet)
My Vray version is always the latest.
I have absolutely no idea how to recreate this error - It’s one of those things that just happen without a real pattern - sorry.
