it worked for the most part, but I screwed up royally in the end. what I did was import a makehuman model into blender 2.79 for testing purposes. I haven't been able to find an automated way to do what you are asking, but I did spend some time today attempting to do it manually. I know something similar has been asked several times in regards to adding multiple textures to models - but now I've successfully added all the textures, how do I pack them together please? Is there a way to get coppercube to pack them? Or does anyone know a reliable way to pack them manually? Problem is that "Pack All Textures" is greyed out (only seems to work for static meshes, not animated meshes?). The documentation advises to "pack all textures into one", to massively improve game-performance.
I noticed that the models I'm using have multiple textures (15 textures in some cases). My game is running a little slow on some machines. The nice thing about blender is that you can consult the source code for the implementation of the uv unwrap methods.Ambiera Forum > CopperCube > Help with CopperCube There are other methods to accomplish this as described on the blender unwrap page. Option: 3Ĭonsult academic papers and opensource libraries/tools like blender:īlender uses methods as described above to unwrap arbitrary geometry. An example object would be to project onto a cube. This provides a mechanism for unwrapping the uv's in a structured manor. You surround the object with a known 2D mapped shape and project each triangle onto the shape based on its normal. This allows for easy UV mapping from a single image. Usually it is ideal to fit the UV's within a unit square. This is the layout stage that defines how the vertices are layed out in the 2D space. The next step would be to spread out the triangles to fill a certain space. This solution is not ideal as it places all of the uv's on top of each other. project to plane defined by normal to avoid stretching So the most naive solution without any assumed structure would be to: for triangle in mesh: Each triangle on the model is a flat surface that can be mapped to a 2D plane.
