Title: VolumeGrid VDB file not loading
Post by: Myrach on 2019-01-13, 19:50:43

Hey guys ,

I'm starting to use Corona and I love it !
However I'm trying to load a VDB in corona volume grid but nothing happens , the volumegrid simply keeps saying "no data loaded" although I tried multiple times in different scenes.
Is there anything I'm doing wrong.In the statistcs ,under volumegrid parameters ,it says "unable to load fire.vdb"

thanks for any help provided.

Have you tried loading the VDB using some other plugin/software? Maybe it's corrupted?
Can you upload the VDB file for us? (see my signature)

Works for me, attached after some small tweaks just for appearance (changed to channel mapping, used autoscaling in the Channel color mapping, lowered the scale) Corona 4 Daily Build Jan 10th.

Which version of Corona are you using, btw?

Shouldn't be, the only change in the daily builds relating to the CoronaVolumeGrid is "Fixed occasional flickering of CoronaVolumeGrid when using velocity-based motion mblur".

EDIT - here's what my statistics look like on loading, what does yours show?
