Arnold volume does not recognize grids

[honorsforgod]

Arnold volume does not recognize grids but c4d native VDB volume works fine

[peter.horvath6V6K3]

Maybe it's an OpenVDB version issue. Can you send us a VDB file to check?

it's even caused the crash [GPU], when i delete the volume from my scene everything works fine

[madsd]

So, this works fine in MaxToA.

I can call the 3 channels, flames, temperature, density which are visible in the VDB.

I can call them through OSL 3dtexture(); call and by just injecting the string names to the Arnold volume material.

This is what I get.

[honorsforgod]

yeah correct that's it, so odd

now I am able to load it

my scene: atmospher_Volume and VDB volume[fire] and mesh light for rear lights of the car

when I delete the fire ---> GPU OK

when I delete the car and keep the fire only ---> GPU OK

everything in the scene ---> GPU Crash

[peter.horvath6V6K3]

I can not reproduce the crash. The vdb and the grids are loaded and rendered fine on CPU and GPU. Make sure you are using the latest C4DtoA 4.0.3.2. From the log it seems the Optix denoiser is enabled. What if you try without that?

[honorsforgod]

I disabled denoiser still keep crashing, yeah I using the latest one C4DtoA 4.0.3.2

[peter.horvath6V6K3]

Any chance you can send us the scene? You can send it to support(at)arnoldrenderer(dot)com

[honorsforgod]

it's not a simple scene to compact and send. it has a lot of material with external texture and large VDB files and Alembic involved too
