@solo said: Very hard to say what is going wrong, will need more info, maybe images will help Thanks Solo, i will try to explain... the sketchup model has a lot of textures files, I export to obj but is something wrong with the way I export obj, probably i will have to optimize the textures. The obj files which work with my software have only one or a few texture file. The problem could be the way I edit the modell before export it. My machine only accept .dxf and I don't know how to convert with textures definition. only the block is converted.
