Difference between the setting while importing .OBJ

Corona Corona for Cinema 4D General
1

I noticed today that while importing the .obj files with the UVs for textures and Vertices I can not use the C4D material editor. It is not visible in the corona render, however when I import .obj without the UVs and Vertices boxes ticked on - I can easily use the C4D material editor.

Is it just me, am I missing something or is it just a bug of the beta version?

I don’t understand your problem. It looks like you messed up importing the file with the wrong settings or your file requires a specific preset. However it doesn’t look like a corona problem but a mistake importing into C4D.
Add a screenshot so we can see what the problem is.
