Some people like using Unreal's Volumetric Clouds system to render VDBs (check the example levels in the Release packages) and it solves some of these issues when using the right options (tip: check "Apply Cloud Fogging" on your translucent materials), but you will loose my core VDB rendering features.

Can i fix that ? + +For now the plugin forces all imports at 30fps. To get back to 24fps you will need to slow down the sequence play rate by a factor of 24/30 = 0.8. +* You can change the realtime in-game sequence framerate using the "Playback speed" option in the VDB details panel. +* If you're using the sequencer, right click on the sequence and change the "Play Rate" option. + #### Can I only render VDBs using the Movie Render Queue (MRQ) ? The plugin comes with two post-processing materials *MovieRenderQueue_VdbColor* and *MovieRenderQueue_VdbAlpha* that can be used as custom render passes with the Movie Render Queue (MRQ).
