Hi,
Please update corona converter 2.4.0 by adding some direct conversions:
VrayUVWRandomizer-> CoronaMappingRandomizer
OR add at least a warning messeage to ErrorMessage Window with ability to select not fully converted objects/materials.
I think it's unnecessary to explain how painful it is to find random, forgotten V-Ray maps - and as a result, broken shaders - especially when Corona actually has equivalent maps.
Thank you
