When importing Geometry from Arhcicad over to Blender it all works fine - great job, love your work. However the UV Maps are causing trouble once a wall is cut and has an extra material ontop.
If you have four walls intersecting, forming a rectangle there are at least two walls which are being cut short (lets say at the short side) by the non-cut walls (lets say the long sides). If you set all the Materials up to be Concrete but give them a texture from all sides (allegedly including the cut-surfaces) the Walls that are uncut will import with one Texture with sometimes correct UVs while the cut ones will get two textures with completely janky UVs. As you’re placing a lot of walls in Archicad that becomes a problem rather quickly.
The hope is to somehow tell all walls to only have one material and have that mapped correctly. The UV Mapping on simple walls is hit or miss anyways. On the first import of the model at least the main wall was working… now nothing loads with a texture map and I have to manually assign them a Cube Mapping. That is unfortunate as the correctly mapped textures in Archicad mean that the information must’ve been there and be lost on the way.
Does someone have a workaround? Sometimes I can pull the model over to blender and remap the textures and I am good to go. But most of the time I spent so much time UV-Mapping everything… I must miss something.
