Having fun with clouds

[Oleg_Budeanu]

you will be dissapointed as there are some issues with layering up aerialperspective and vrayvolumegrid.. i.e. it doesnt work..

Yeah looks like there are. Well there is zdepth anyway

This looks promising. Good Job Oleg!

Thanks, Oliver, next i will do more "mixed" clouds , different sizes and more detailed.

Have here a problem actually , for some reason when i import a VDB file from houdini to VRayVolumeGrid - it is empty. Though i'm pretty sure it should be fine , as it weights about 10mb , and in houdini it previews fine. That should be some settings in VRayVolumeGrid ? In input size it is empty and looks like a point for some reason.

Didn't u merge volumes in one ? There were some problems with that, 'coz H can merge volumes in various ways...

Yeah well i'm kinda new in Houdini Though i resolved issue - problem was VDB converting node - some parameters in it were wrong.

only if you render in geometry mode which is very slow to get the same look
i suppose this is to be expected and i ended up doing a zdepth in a seperated pass with low bounce settings to get around this

Yeah looks like for now this is the only way.
Here you can check new update , this is straight render. On the background for cirrus clouds i used HDRI from noEmotion guys (thanks for that one!)
