3ds max VRmat material gamma problem

[sassom]

I usually work with VRay for 3Ds Max, and now I'm testing VRay for Revit.
I'd like to create vrmat files, which can be used in Max and Revit too.

I have exported a few Vray materials from Max to into vrmat files. However, if I render an object with the same vrmat file in Revit and Max, the gamma value seems to differ.

If I set the gamma of the bitmaps to 1 in the VRmat Editor, it looks OK in Revit (looks the same in the VRmat editor too). With this same vrmat file loaded to Max, it looks like it has doubled gamma when rendered. (The original VrayMaterial, which I exported the vrmat file from, looks OK in Max though.)

If I set the gamma value in the editor to 0,4545 it looks OK in Max, but looks too dark in the editor, and Revit.

Is this a bug, or I just have wrong setup?

thank you

Hm, we have to check that. Can you attach some .vrmat file that has this issue?

I had the same problem between Rhino and Max
ended up using Notepad++ to edit XML and force it to 2.2

I believe we've already discussed that matter into the thread bellow but we couldn't reproduce the issue.

I've just tested the material you sent us before and I again got very similar results:

Except the .vrmat files that vlado already requested would it be possible to attach Revit and 3dsMax scenes so we could better investigate if this is a bug or if there is something wrong with the setup.

Looking forward to hear from both of you.

Here you can find my test with max and revit files included.
