Irrlicht Engine

ok i am having a wierd problem, my mesh which is in .obj format LOSES its textures when it loads! leaving me a black mesh lol. how do i fix it?

I hate to be the bringer of bad news, but as far as I know .obj doesn't support textures at all. All it has is B/W.

just manually add the texture map works a charm here apart from the edges look kinda rough. I'm guessing none of the info held in the .mtl file is loaded.

.obj does suports materials (with textures) but they are not contained in the .obj file and must be in a separate .mtl file. Unfortunately Irrlicht does not load these

I had the same problem some days ago.
Cound not find a working solution for that problem.
Just to add
object->setMaterialTexture(0,driver->getTexture("texture.jpg"))
is only a workaround.
But I am afraid it's not a good solution because all the texture mapping will get lost.

My hope is, Niko will add a little more support to the wave format.
Then we could use "Art of Illusion", which supports wave output.

A year ago I was playing with irrlicht and with an OBJ-model made with lightwave, and I had a similar problem. I remember that I fixed it, but it was more a hack, and thus I never send the fix to Niko.

Maybe some of you wants to write a patch??

As far as I remeber the OBJ-format worked like this:

you declare a list of vectors, texture coordinates, colors whatever, and you define triangles saying:

triangle should be composed by vertex 501,123,126, it should use color 127,456,343 at each vertex etc.

But OBJ also supports negative indeces for vertices etc. to count backward, i.e.

triangle -1,-2,-3

would be a triangle, which is composed of the last vertex defined, the one defined before, and the one defined before this other one... I don't know if it is clear, what I mean.

The problem with irrlicht is that it does not implement counting backwards.

If you try to correct this, good luck.

thats ok im not a good enough coder for that lol, im just going to switch to .3ds format.
