First of all: I know a couple of things about Blender but in the end I’m still pretty much a beginner, especially when it comes to textures and that’s exactly what I’m currently having problems with:
I downloaded a couple of free models (a plant (.fbx), a bench (.blend) and a door (.blend)) that all come with texture files (.jpg/.png) in the extra “textures” folder. I want to import these models in Blender, then export them as .obj files that I can then use in Unity but so far I haven’t managed to texture even one of the models properly.
1. Plant (.fbx): When I import the .fbx file (“source” folder) there are no textures and the leaves of the plant are rectangular sheets. There are 14 .png files but how do I apply them? I also downloaded the .glTF archive and the textures show up in Blender with “Viewport Shading” active but when I open the exported .obj file in Blender or Win 10’s 3D Builder, the leaves are just rectangular sheets with the texture mapped onto them (.obj supports alpha afaik, so not sure what happened there). Same thing in Meshlab (plus the actual pot partially uses a leaf texture) and even in Win 10’s 3D viewer the textures are all over the place.
2. Bench (.blend): In Blender the main wood texture was missing but I managed to set the right file through the shader editor. The nails are the bigger problem - they don’t use an actual texture file but are textured by the shader. Exporting this model as .obj file got rid of the main texture again and I had to add it back as “map_Kd” in the .mtl file but in the end the nails are still missing their texture. I tried to work with the .glTF export instead and even though the nails’ color shows up correctly in Blender and the 3D Builder, the resulting object is huge (much bigger than the original)!
3. Door (.blend): As with the bench the textures are gone and this time there are no nodes in the shader editor but 3 textures (for 3 model parts). I managed to set the frame’s texture through the “Materials Properties” but this setting section doesn’t exist for the other 2 parts (actual door and lock). How do I set their textures properly?
Is there a general approach for models downloaded from Sketchfab? Unfortunately so far none of my downloads just worked as-is.
