I am a railway modeller, I can design and add basic textures in SketchUp, no problems. I needed to up the texture levels quellenform istructions put me right so now Walls with real life textures are possible. I made a couple of how too videos aimed at the newbie like myself on my YouTube Channel. I am trying to pass on the knowledge and the response was great.. My question is how do I convert a SVG/STL/DAE type file in Blender to a single mesh with no subdivisions so I can add displacement texture. I can then cut out windows using the Boolean method later once the texture is applied. I have Construction lines addon installed, would this help?
