Hi

I read that there's a bug in the latest octane for modo plugin (3.06.1.120) from this post

viewtopic.php?f=34&t=62486&p=319335&hilit=vdb#p319335

I don't know if the issue I'm having with VDBs in Octane For Modo is related or not to that bug. I'm Uploading the images and .LXO

I downloaded these .VDBs from http://www.openvdb.org/download/
And did a setup in MODO 11.1

Octane renders the "fire.VDB", but not the "bunny_cloud.vdb".
I also dd a test setup with a sphere mesh as a vdb source. Octane doesn't render it.
Are the bugs related? If not is there a fix for this problem?

Thanks

Best regards

Hi - I am midway through putting together the 3.07 build of the plugin, so could not do a full test, however "Teste 92_VDBFromMeshOctaneNotWorking.lxo" rendered OK for me - so it would probably render OK with the latest version of the plugin available in this forum. I will test the other files once I get further through the Octane 3.07 build.

HI

Thank you for the information.

however "Teste 92_VDBFromMeshOctaneNotWorking.lxo" rendered OK for me - so it would probably render OK with the latest version of the plugin available in this forum

I'm using Modo 11.1v1 with the latest version of Octane plugin downloaded from the forum (3.6.1.120). "Teste 92_VDBFromMeshOctaneNotWorking.lxo" doesn't work

I wrote in the initial post that i was using "Modo 11.1", but i'm using 11.1v1. Don't know if that could make any difference...

Thanks once again

I'm using Modo 11.1v1 with the latest version of Octane plugin downloaded from the forum (3.6.1.120). "Teste 92_VDBFromMeshOctaneNotWorking.lxo" doesn't work

I will have a new version of the plugin available in the next day or so - pls try with it, as it's working for me on that version.

Thanks

Paul

Thank you Paul.

Hi Paul,

Downloaded and installed the test build 3.07.0.123

However now none of the examples I sent earlier are rendering, even the one that worked previously.

"bunny " : Still not rendering

"fire" (this one worked previously): not rendering now

"from mesh": Now i can edit the nodegraph connection on the octane override in the "mesh connected to vdb source". Previously it wasn't working. Still not rendering

Hi

Here's a screenshot of the fire.vdb after installing test build 3.07.0.123

Remade the scene with all the steps in Paul's video tutorial (link below), in case i was missing something.

Octane doesn't render fire.vdb volume anymore

(the other ones, "vdb from mesh" and "bunny.vdb" still don't render)

Thanks for any help in solving this vdb problem

An update:

Inside Modo if I export "OctaneVDB_FireNotWorking.lxo" to .OCS format, and then open in octane standalone 3.06.4, it renders ok.

In Modo I made a simple setup using a particle simulation as a vdb voxel source, and then connected this vdb voxel to a volume.

Octane Plugin: does not render
Then I exported the scene to a .OCS and opened it in Octane Standalone: rendered ok
I don't know if this helps finding the problem, but i'm posting anyway

Thanks

These issues appear to be a problem with Octane 3.07 test 4. I have reported the issue to Otoy.
