  • Can't see LC calc progress when using DR. VFB is black.

    I've noticed that when I use DR with RT CUDA I can't see the light cache calculation phase. The VFB is just pure black until LC is fully done. The rendering proceeds as normal after LC is done. Is this normal? I like how I am able to get a general idea of the scene and lighting before the actual rendering starts and seeing the light cache calculation gives me this possibility which is nice.

    If that helps, the hardware and software of the DR slave is the same as my signature with the only difference being the GPUs - it's just a single GTX 980. Let me know if you need a scene but it does this in pretty much every scene AFAIK.

    Hello,

    Yes for now this is the normal - the light cache preview is not transferred in DR.

    Best regards,
