VrayIes ies location not affected in bitmap / photometric path editor

I cant change the path of the ies file in the bitmap photometric path editor.

Have you tried changing it in Asset Tracking?

Unfortunately we cannot do anything about this; the utility is hard-coded to work for specific plugins only. A work-around would be to use the Asset Tracker, which also works for things like proxies, VRayHDRI maps etc.

Best regards,
