    UI Corrupt on Render

    Hi,

    I could find anyone mentioning this on the forum but, I have been getting this on two different machines.
    This only occurs occasionally but, the all the controls for the light, materials etc in the properties panel disappear.
    They return once blender is restarted. I have tried different Window Draw Methods but it continues to happen.

    Any ideas?

    Thanks
    Dan

    I'm using the latest vray blender custom build both 32 and 64 bit. Using the latest version of vray, version 2.0.20.

    Thanks again.

    Do you see any error message in the console when this problem happens?

      Hi
      This is unfortunately some bug with blender, was supposedly fixed months ago but still pops up again randomly I find as well.
      Albeit much-much less often than before the fix. Prior to the fix we could drop the UI like this by just swirling the colour picker around repeatedly.
      Now I see it at most 1 time a month.

      If you can make this problem happen pretty often I would recommend to report a bug at blender bug tracker.

        I know what you mean, I'm sure I have seen this in the past with Blender, but I don't seem to get this anymore in Blender alone, I only get this in the custom build when using VRay. Also I get it very frequently. Sometimes I can go an hour or so without a glitch and then just now I've had it happen twice in a few minutes.

        The console displays many various versions of this error. let me know if you'd like to see more of the errors.

        Code:

          It seems related to game engine... in the script there is a note and tells to not use node material. Try this, I'm not be able to replicate this bug.

            I don't think it's related to the game engine as a whole. That example of the error mentions the game engine, but there are other parts and I didn't want to post a long list but to make things a little clearer I will post the whole message I managed to capture.

            All the errors on this example seem to be involving the properties_material.py from both blender and the vray addon.

              Re: UI Corrupt on Render

              Other deep scripts like luxrender and I think indigo have seen this problem too.
              I have never seen the problem without having an external render engine script running.

              I'm having trouble finding the old bug report on blender, but it had a comment after being fixed that not all cases may be handled. (or something to that effect)
