I'm asking if one model with multiple textures can be exported with multiple alpha channels?  And how can the alpha channels be turned on in processing?

Is Opengl's coordinate system different when I access it directly.  My model is oriented very strangely.  When I sgsrules' library.

this is just a suggestion.
have u ever thought of loading multiple object obj files ?
i gave this lib a try and when i tried to load +2 objects in a obj scene it crashes..

sure.. this is a tree sample made of trunk, branches and leafs..
it uses relative coordinates and seperates all objects..

check this:

polymonkey,
i havent wrote any code. i basically gave a try to objloader and tried to load that obj file.

it crashed, and i thought it could be that the obj has multiple objects. ive exported it as a single object scene and it worked.

i just wanted to tell u that. maybe you could implement that in the lib. it would be good for me as a user. you would save me alot of work =)

Nice work, I'll look at getting group support into the objloader in the coming weeks.

hello.
first question: i started using sgsrules's objloader and it works like a charm (great speed!).. many, many thanks for it. anyway, i know there have been some dramatic (big word, but true) changes in opengl as from processing 144 and therefore i noticed the textures are displayed kinda' different, as in 148 are displayed upside down and in 135 correctly. i solved this by loading the texture as PImage, rotating it and then creating an ImageBuffer from it with the setRGB(x, y, color) function, then binding it on the object loaded with the objloader. while this works, i think that there is a setting in opengl that deals with an option of automatically rotating textures when binding them on objects. how can i access it? (if i can).

second question: you probably figured I'm not so experienced in opengl in java. therefore i ask: some exported obj files contain more objects with different textures each. in sgsrules's example, we bind a texture to the whole obj file. how can i bind different textures to different objects? (they are specified in the obj file).

thank you in advance.

thank's very much for the reply, texturing problem solved (such a n00b i are).
now, i know about mtl and i just export a 3ds file with meshLab (open source) into an obj and all the work is done for me, so at least this is easy i was talking about sgsrules's objloader, because it doesn't really seem to load anything from a mtl as far as i understand it (it doesn't really need it). i have to load/bind the texture myself and the only code i know is to bind it to the whole geometry of the imported obj file. now, how can i bind it to separate elements of the obj?
