This is not a highly technical post. It is geared towards beginners who like me bumped their face into a problem very simple to resolve. So, you are new to SketchUp, cool tool huh. You create a box house, start a texture, import it, and apply it to your model. So far so good. Need to modify the texture? So you go modify the original then what? It's not reflected in SketchUp? When importing a PSD, BMP, JPG or whatever texture, SketchUp doesn't actually work with that file but with a JPG copy of it. In order to modify it press ucket, select the texture, right-click, click on 'Edit Texture Image...' When you follow the MCX process to create an MDL file the JPG texture will be copied to a final BMP file (make sure you select the proper path). What I don't like about it? I start my texture as a PSD, SketchUp makes a JPG copy, MCX creates a BMP version of it. 3 copies of the same file to keep up with.
