Hello! Got an issue with importing sketchup models and the problem with materials. Previously, I think in Corona 10 I guess it was fine and sketchup materials appeared like standart 3ds max materials and looked ok in viewport, at least textures were visible. Since Corona 11 and further models imported from Sketchup apperars like totally black and it slightly harder to work with. I checked if the problem is from the sketchup side and tried some older versions of it, but problem is the same. And converter not working with that kind of materials, so on render it appears like red warning obviously. If there any ways to fix that? Because now workflow is looks like changing all materials to corona standart manually aplying it to selection and coloring it again with some other materials.
I think 3dsmax importer changed, not Corona issue
Autodesk changed the default sketchup importe to a new ATF based importer which means new importer brings sketch up material into 3ds Max as Physical materials instead of basic standard materials. So you can use Corona converter to convert your scene material to corona compatible materials. let me know if it causes any issue.
