Hello. I tried make model simpliest as possible it is 7661 triangles for everithing and three 1024x1024 diffuse textures. Nothing more. Only handpaint. For modelling I have used Blender, for texturing Photoshop 2017 and also Blender. My results: model
@Larry sorry, I tought you were using materials which are external to ue and you had image texture of the diffuse, normals, specularity and so on. Do you have a way to get those textures from the materials? If so, you could just use blender to bake them onto a single texture
@Larry you can either texture paint the whole model on a single texture, or you can texture the various parts separately on their own texture map, then you combine all the uv maps in a single one and you bake the diffuse map, the specular map, occlusion map and so on. I'm not sure I've explained myself very well XD But you…
