I'm using Fume 4 to export VDB's. When I load the VDB into Vray's VolumeGrid there are tons of problems. I can't load my fire, the smoke loads but it renders incorrectly. I have 2 versions of Max open currently and with Fume rendering and VolumeGrid rendering. The caches look totally different.
Any idea how to fix this?
:::edit::: In 3Delight, you have to select the Oxygen channel for "Fire Color" for fire to actually show up. Still trying to find out how to change Vray channel selection.
:::edit 2::: I reran a sim that does not export the oxygen channel. I exported everything else but oxygen and Vray's VolumeGrid still can't read in temperature. It also renders smoke incorrectly still. In the "Cache File Content" it can only see the Smoke VDB channel. When I load in a field3d cache, it sees all correct channels. It looks like Fume's Channel's are being mapped out incorrectly. I know that you can remap the channels using 3rd party imports, however it would probably help to be able to do that for exporting because VDB is esentially useless in Vray's Importer. But, in 3Delight the smoke does render as expected because you can select the channel; although slowly.
