Did I miss the memo? Volume Hyprevoxels don't get lit by radiosity? Surface works everytime, and Sprites don't.

Yes Volumetric Radiosity is on - wouldn't affect Surface hv otherwise - tried all illumination models, gi types, quality settings, it'sa black everytime.

Yeah, I guess you'll need to bake it...which you can't save/load with the scene: bug 39849 (https://fogbugz.newtek.com/default.asp?39849_h8jp76cn) that NT never fixed, but for some mysterious reason closed. NT?

Just wondering, was it ever implemented? Just tried 9.6 here, doesn't work there either, so this is not something that has changed in 10/10.1

Perhaps this is a limitation in Volume HyperVoxels that has simply always been there as oppose to something that has broken?

I'm not entirely sure, so if someone wants to go back further and let us know.

Could be that it's tough to code and too render intensive for most uses to go to the trouble.

To me it sounds that it never has been implemented for hypervoxels, there are only two lights to choose from for illumination, and the alternative use all lights.

Dont know if Afterburn for 3d max has global illlumination?

GI does work on the Surface hypervoxels.

Matt, do you know why the HV baking bug was closed and if it will be fixed anytime soon? In my email exchanges, NT dev had acknowledged the issue, but the issue is still closed without that getting fixed.
