this would be really nice.. vray does it since the start (uv's are stored inside the proxy info)
there are also some models (maybe not 100% correctly build? or simply too large?) that produce an error when exporting.. vray on the other hand can export the exact same object within seconds :/
dont get me wrong on this, vray had its days by now, sure there are some things left that vray does better but only because they had more time over the years to develope... i really enjoy and love corona, as soon as
- proxy (export/datalimit?/teamrendering)
- corona DR (hopefully it will be more stable/faster/flexible then teamrender)
- node based editor
- and ofc finally fixing the composing tag (shadow catcher *cough*)
are fixed, corona will pull ahead by far.. even without those 4 things the lightmix alone is more then enough reason to use corona over other engines atm for me..
