Chaos Scatter with VRayVolumeGrid

[alessandro_dele]

Hi, sorry i'm learning vray and i'll be here for a while asking questions

I've tried to scatter a volume grid in chaos scatter but doesn't workd, am i doeing something wrong?

Also i thought to try instancing a VRayVolumeGrid with bifrost but i got this

// Error: VRay: Could not load the Bifrost module! You will not be able to render Bifrost as isosurface or metaball. The error message is:[loadLibEx] 126: LoadLibrary failed (126):

I'm using the latest bifrost 2.12

Thank you!

That error btw is for the old bifrost stuff (blackboxed), Vray does not support the Bifrost Graph yet out of the box, soonish let's hope, supposedly they are working on it!

You can though render stuff through Bifrost USD using the graph with vray in the meantime. So you could use the USD point instancer in the graph for the volumes and render straight out using from there (You need to output the stage) or you could use points in Bifrost to copy VDBs then save the VDBs using the write VDB node and load it using the volume grid node in Vray.

As hsz said, V-Ray supports the rendering only of Bifrost USD graphs. Also, that error usually occurs when the Bifrost version is not supported. I'm not sure if 2.12 is (I'll ask the devs), but I have 2.11 installed and do not get the error.

Thank you! I'll try the 2.11, so i could try to scatter the vdbs inside bifrost and the add them to a stage in the scene for render with vray?

I'm not too familiar with Bifrost to give you a precise workflow. Try what hsz suggested and see if it works for you. Otherwise, I'll get somebody else to help.
