  • Missing materials when updating to vray 7

    Hi!

    Anyone else upgraded to vray 7 for rhino (rhino version 7) to find many materials missing, or materials just not working with previous project files created in vray 6?

    I remember this happening back a few years ago when we had the transition from vray 5 to 6.

    Any work arounds or solutions whould be welcome.

    In the mean time I have reverted back to the latest version of vray 6 for rhino 7.

    Many thanks

    Hi ZAM BER,

    Can you please describe the issue in more details?
    Are there specific materials that do not load or is it random?
    Can you share an example project that you can reproduce the problem with (we need the original version of the file, not the one already saved with V7)?

    Are you opening projects saved in V-Ray 6 to find materials missing in V-Ray 7?
    Note that V-Ray 7 files are not compatible with V-Ray 6 and opening them in V6 will most certainly result in data loss.

    Regards,
    Konstantin

      Hello,
      I have a similar issue.
      Some materials are missing in the Rhino viewport (simple bitmap texture) and some of them are shown differently : for example, a modified texture (mix map color) in the diffuse layer is not shown properly in the viewport.
      It is ok in the render though.

      I checked the Rhino viewport configuration (display properties) and I have selected "rendering material" & checked "advanced preview texture".

      Any solution ?

      Thanks !

        Hello kevin_sourivong ,

        Thank you for your report.
        I identified an issue when scenes from V-Ray for Rhino 6.10.03 or older are opened with V-Ray 7.00.00 or 7.00.01. The issue is that materials with texture networks containing a Bitmap (e.g. Bitmap wrapped in a Mix Map, Color Correction or others) have the Bitmap set as a Viewport Texture:
        Click image for larger version  Name:	Viewport_Display_Texture.jpg Views:	0 Size:	88.8 KB ID:	1223427

        If you delete the Viewport Texture map the texture network will be baked and Rhino Viewport appearance will match V-Ray.
        The issue is logged in our bug-tracking system.

        However I could not reproduce missing materials in the viewport with V-Ray 7.00.01. It does happen for me in the older versions - 6.20.00 - 6.20.06, but after modifying a material (e.g. disabling and enabling the Diffuse texture checkbox) it is then displayed correctly in the viewport. Which is the V-Ray version you are using?


        Kind regards,
        Iva​​
