Multi textured obj with blender how to.

[pithy]

1: First you will make the mesh.


2: Then make each part that needs its own texture a separate object.


3: Export as OBJ. Minetest does not use materials and disabling it will save a bit or two. Check "Objects as OBJ Groups" and uncheck "Objects as OBJ Objects". I don't know why but it is needed for multi texture support.


If you do not need texture syntax compatibility you can stop now.

4: Rename top to f, bottom to e, right to d, left to c, back to b, and front to a.


5: Export as DAE. Check "Sort by Object name", it is needed for texture syntax compatibility. Watch out for "Triangulate" but you don't really need to.


6: Import the .dae and export it as OBJ following step 3 again.

Then you can use it in minetest.


P.S. If you are a maintainer of moreblocks you should look at the pull requests.

I might add that you can also use multiple materials to do the same thing with a single object, that's how I usually do it anyway.

btw, I do not understand the need to export as .dae and then re-import, that should not really be necessary.

That works in blender but does Minetest really read materials?

The order of the textures is +Y, -Y, +X, -X, +Z, -Z and in some use cases the object order needs to match.

Maybe not in the case of .obj, I've not actually tried it to be honest. It does, however, work for animated formats like directx or b3d.
