I have a box (as a placeholder test) which has a different texture per face, when I load it into AppGameKit all I get is a white box and setting the object image sets all faces as that texture.

Is there a way to texture each face using a separate texture?

I want to have a big room which will use loads of textures and having them all on one big texture is not an ideal situation. I have loaded into Unity and it works as required.

Ypu have to load the more using LoadObjectWithChildren, then if its built correctly you will be able to access the individual meshes. .obj files I have found a pain, .X and .fbx work best.

You dont have to loadwithchildren to get multiple meshes. (only really for animation and children). Just LoadObject will load multiple meshes into the one object.

You will have to use SetObjectMeshimage() multiple times though. Once for every mesh in the model. You can use GetObjectNummeshes() to check you have all 6 sides.

You can then set an individual image per face with SetObjectMeshimage().

I'll have to go back to this....normal load object never worked for multiple meshes for me, perhaps its just the .obj format I'm saving in.

I thi k the issue is materials I had, and possible MilkShape. It seems that, according to documentation, AppGameKit loads models using the lowest amount of meshes possible, and it seems to do this via materials. What I've found is a model with 3 meshes with no materials set as a .obj format loads with one mesh. If you set them with 3 different materials and save them (not UVs) then you get the 3 meshes. If two meshes share the same material, you get two meshes, one for each material. So it seems AppGameKit uses material data to decide how many meshes to have.

So the rule seems to be use a modelling program to set up materials....or use something better than MilkShape.

The .obj format can have groups and objects. Maybe it's exporting your meshes as groups?
Do you have a sample .obj file?

If you use milkshake also use something like Ultimate Unwrap to texture as milkshake can muck up some of the exporting.

I use Blender for modelling and UV mapping, I only use MilkShape for exporting as the newest Blender doesnt have .X exporting yet.
