Steps to Reproduce

  1. Place a heterogeneous volume in the scene.
  2. Change render cam to orthographic.
  3. Launch in standalone -or- package project and play

Expected Result

Volume should render normally at full detail.

Observed Result

Volume is rendering at incredibly low, blocky detail; the same as if you alt-tab out of the viewport. Occasionally it flickers to full detail for a couple frames.

Update: Setting the streaming mip bias of the volume or using command:
r.SparseVolumeTexture.Streaming.RequestMipBias -10
can circumvent the issue. LOD’s not working properly in ortho.
