    Urgent suggestions needed. Small vrayLightmat objects flickering.

    I've got a scene with loads of blocks of varying sizes with vraylightmats applied. The smaller objects flicker randomly for some reason.

    I'm using "sub-pixel mapping", Adaptive-dmc 1/24, Noise Thresh of .005
    No GI.

    There are NO coplanar surfaces although it does look like its a coplaner surfaces problem.

    Any suggestions?

    Can you show a crop of a few frames?

      Will do... is it possible that using the DMC sampler is the problem? Initial tests suggest adaptive subdivision fixes the problem... although that's just from rendering some stills, so there's no guarantee that its fixed.
      Also... if it matters.... I'm using Area AA. (I'm now testing without AA)

        Yep. I can confirm the problem is fixed using no AA and Adaptive Subdivision sampling....

          Hmm.. I spoke too soon... flickering still visible.
          AND it looks like I didn't have SubPixelMapping enabled.... Switching on Sub-pixel mapping seems to stabilise the flickering.

          My mistake
