VDB from Camera Frustrum

Recommended Posts

This seems like a simple one, but I must be missing something. I would like to create a vdb from a camera with fog volume values inside the frustum area.

When I choose 'From Camera' the vdb sop node shows me a frustum guide with appropriate dimensions but it always gives me 0 voxels.

This is Houdini 16.0.633

Yeap I believe this has been a bug since the 16 release. Unless we are both doing something wrong... My workaround was to either create geometry which represented my frustrum and then vdbfrompolygon. Or you can try the volume sop and then converting to vdb.

Good luck!

hey,

it is actually working (16.0.621 in my case). perhaps you have forgotten to activate the vdb region? (place a vdbactivate after the vdb sop that is getting the cam frustum)
