I am having a bit of a problem solving this one. Dont know what is causing this… have a look at the image and files attached. If rendered with c4d render the look is as it should, corona looks like is messing the phongs shading.
This never occurred to me it’s kind of weird.
I am running corona beta September 5 on c4d r18.
Perhaps it’s a bug from that built, don’t know… I have to try the latest built and hopefully will solve.
