black rendered frames

[takehito_iizuka]

Hi,

This might sound like really daft question but I have no luck getting any frames out via USD render LOP, initially I thought it is due to beta version og 19.5 plugin but I am getting same results in 19.0 with stable version plugin. All frames are black and console output indicates that not much is happening, no textures loaded etc.
Viewport works just fine.

Fedora 35, Houdini 19.0.657, latest stable version of vray.

1. Will this work without denoiser?
2. Are there any AOVs? Are the all black?
3. hip file?

1. Doesn't look like
2. No AOV are currently set up.
3.I set up very basic scene with rubber toy, the only non-default setting is image sampler set to bucket. Renders in viewport but USD render LOP throws this error:

Failed to load "/usr/ChaosGroup/V-Ray/Houdini_19.5.303/vfh_home/dso_py3:/usr/ChaosGroup/V-Ray/Houdini_19.5.303/vfh_home/dso_py3/vray_for_houdini.so"!

Could that be because of fedora 35 ? I ran into similar problems with other software but was eventually sorted (Houdini included)

This error was fixed last week, but the code that produces this error is used only for volumetrics.

And it seems to work for me both on Windows:



and Linux:

Thank you, I will investigate further. Is that on latest Linux Mint ?

I reinstalled latest vray plugin and ran test scene again and here is console output. It appears that plugins loaded successfully but the result is the same. There is also no mention of any textures being loaded other than hdr for dome light. Viewport rendering works fine now (as opposed to all gray materials)

CentOS 7.

I guess there is some message limit, could you send me the full log by email in my signature?
