Whilst this duplication may not be an issue in its own right, if the Window has thickness - it's not just a single planar surface - this can mean SketchUp has actually drawn four or more surfaces - an outer and inner surface for each 'front' and 'back' plane. In addition to this, for SketchUp to texture both sides of each window it has to duplicate and invert the mesh, creating a 'front' and 'back' (or 'inner' and 'outer' surface) that, alongside individualised Material assignments, can then be textured independently if required - double-sided in other words. In other words five distinct and separate Materials referencing the same Texture/Image data. Shown below for example is a section of a SketchUp building after import into Blender although all five window sections are UV mapped using same bitmap image (a glass block - not transparent), each has its own individual Material reference. And whilst SketchUp does provide a number of export options they don't necessarily address this issue of over duplication directly (as it relates to game content), so content often needs to be further edited and optimised in more meaningful ways in Blender or other applications. Whilst this allows for both the inner and outer surfaces of a given mesh element to be textured with relative ease and independently of each other, it tends to be problematic outside the SketchUp environment because the applications is essentially generating too much mesh data for models to be used in game 'as is' - using SketchUp content directly would mean game engines rendering a lot of redundant material unnecessarily, largely because its hidden from view. Redundant duplication ^Īs briefly mentioned in the introduction, SketchUp models are constructed using a lot of duplication duplicate surfaces, duplicate materials, textures, UV maps and so on. Then apply the brick textured material to the wall faces as desired.The following highlights and discusses some of the 'extras, options and issues' that might occur, or there needs to be an awareness of, when importing into and/or editing SketchUp models in Blender. Then Edit the various wall parts in turn, and use a Plugin like thomthom’s CleanUp to remove the selected coplanar edges which are unnecessarily triangulating those faces.
Trying to fix it afterwards is too much of a pain. The way I’d do it is to import it at into a new file at the correct size. When you ‘baked’ the textures for those triangles the texture image does not perfectly follow the sides and you get white-bleeding… hence the spider web look now indelibly baked into the model. If it were unScaled then the material would apply properly. What Options did you choose for the import units ?
Select it and look in the Context-menu to see the Reset Scale option is available - which indicates this. The end wall is scaled down from it’s original size - I suspect 2.54 - inch/metric conflict. Remodeling project (the brick will stay the same). Use SU to examine different siding, trim, and door colors for a Mentioned, I’m new to SU so any suggestions are welcomed. I’ve include a link to the model (below) so you can take a look.
Replace all those with ones created in SU once I sort of know what I’m Some textures were applied in SE, but my plan is to I’m using was created in SU based on picture I took of a wall (cropped Scaled after importing, although I did explode it one level to make itĮasier to access the surfaces for painting/texturing. I did this because it’sĪ lot easier to apply colors and textures with SU than SE. The model I’m working with (of a house) was actually created in anotherĪpplication (Solid Edge) and imported into SU.
