    Freezes before light cache is built!

    I have an i7 chip in my comp wit hWindows & as the OS in case this matters.
    When I run a render with the irradiance map as the primary engine, Dmc as the second it takes about 10hrs t orender an 800x600 image, if I use the preffered DMC primary, light cache secondary it doesn't even build the light cache and instead offers this error message:

    I don't know what to do to make it render. If I open a basic SketchUp file and just click render then it works fine. Help!

    Re: Freezes before light cache is built!

    How big/complex is your model? And what do you mean by "basic SketchUp file?" Could you post some screen shots of what you're working on, just to get a better idea of where the problem may be coming from?
    I am currently using V-Ray 1.49.01.
    SketchUp 8.0.11752
    Windows 7 Professional-64 bit
    Intel(R) Core(TM) i5 K655 @ 3.20GHz
    8.00GB of RAM, 1.2TB Hard Drive

      Yes - a screenshot of your model would help. A render will vary greatly depending on how its build and what light and type of materials you put in it.
      Please mention what V-Ray and SketchUp version you are using when posting questions.

        Just to put it out there. When i have complex models with reflective surfaces. forget about render time... I try and limit the reflective materials when i can. I know its great on most high finish woods but that can definitely change your render times.

          Displacement, glossy reflection, lots of glass, lots of lights all can cause high render time depending on settings.

            Hi all, thanks for your input but I have now sorted it!

            I found a very helpful guy who has a blog about SketchUp and V-Ray and he basically said the same sort of things as you.

            I downloaded a plug-in called "Remove C-G material" which speeds up render times, lowered the subdivs on reflective surfaces to between 8 and 12 and removed some lights.

            All these steps resulted in a 30 minute render of quite a complex shop interior that had previously taken 9 hrs!

            Thanks again for your input though.


            Regards, Kris.
