Irrlicht Engine

Hello,

My model contains objects -> textures -> UV maps (model in maya, uvmap name is the default: map1, there is only one uvmap attached to one object).
My problem is after exporting the model to obj format. The export process is finished. I import the obj to irrEdit as OcTree, this is OK. The model in irrEdit looks good, the uv maps coordinates are there, so I think, the exported obj file contains the uv coordinates -> so I create an irr file with the OcTree.

The problem comes, when I load this irr file to irrlicht project. The uv map info disappears, the textures are mixed.

It can be some irrEdit -> irr file creating problem regarding to the lost uvmap info?

Pls help!

As a general rule, these steps apply in most ocasions when it comes to UV mapping.

-Maybe they aren't on the right texture coordinates channel?
Use only the first one.

-Obj only supports 1 set of texture coordinates, don't use more than one, or else, the info may be ignored.
It is an OBJ limitation.

-Export to another format?
Perhaps .3DS? perhaps .X? the X format supports multiple texcoords via FVF and also supports smoothing groups, or how ever they are called in MAYA

-Check on other model viewers.
Maybe a bug in the exporter, a bug in the irrlicht importer... If other model viewers open it right, you could share the object so the Irr importer could be improved
