Hi Timm. Tried the 1.14 update, and the problems from previous version (with Corona v1) are gone. Nice :)
But.... I do have a question about something I find a little odd: In the Hi Quality materials, "Translucency" is used with a color but without a bitmap, and "Refraction" is turned off (0,0) with a backside image in the map-slot.
I would think, that the backside image should be placed in the Translucency slot, but since you didn't do that, I just wondered.. Is this intentional, or a mistake?
Keep up the good work.
Regards.
