vray standalone can't find vray material library [MTLLIB_DOWNLOAD_DIR]

[sebastian_orosz]

Hi,

I have an installation of Houdini, vray and the vray material library. Using the material library within Houdini on that machine is working fine. But when I run vray standalone from this installation and send a render task from another machine that uses the material library, where a texture is like '$VFH_ASSET_PATH/assets/Metal/Grunge_S_hires_lin_srgb.tx', then vray standalone throws an error:

warning: Bitmap file [MTLLIB_DOWNLOAD_DIR]/assets/Metal/Grunge_S_hires_lin_srgb.tx" failed to load: error in file format:3: Das System kann den angegebenen Pfad nicht finden.' (Yeah, tis german at the end, nice, isn't it? Meaning: Can't find the path.)

So I think there is some declaration missing. I read about a 'vrayconfig.xml' file that can be placed in the bin folder to configure standalone. But I could not find any docs about how the content should look like, especially regarding the missing path declaration. How can I tell standalone where to find the material library?

Hello sebastian_orosz , you should add VFH_ASSET_PATH in "Preserve Variables" parm in V-Ray ROP>Export tab , this way VFH_ASSET_PATH won't be baked into the vrscene.
