[Open GL] Multitexture blending

Congrats

Thanks

And as I have suspected:

Here's a screenie of working (probably correctly ) ligth:

I had depth test flag disabled (or should I say not enabled, cause default is disabled) in my material so the last screenshot still looks a bit weird if you'll give it a closer look. Enabled it and now it works like a charm

This is probably fixed, but I may return to this thread with other questions (so I wouldn't need to spam threads).

Finally got texture to show up

I currently only have TGA loader. (Had to make bunch of stuff just to get into doing the loader).
He looks kind of blue'ish, but I think I just made some wrong settings somewhere.

Oh and excuse dwarf for missing his axe, he said he isn't going to war soon.

BTW. Where is the thumbnail link gone in ImageShack?

It's me again with another problem. I've been trying to add multitexture blending support to my renderer for a few days, though with no success so far.
The code I've tried to use with my renderer was from samples around the net and also generated by this app: http://developer.amd.com/archive/legacy ... fault.aspx

Neither code has worked so far, the results were either black texture, first texture, or white texture. No gl error has happened with either of those situations.

What I'd like to as is what would be the steps to correctly use this technique?

Perhaps some source will help

I couldn't find a single call to glTexEnv. Looking at the path to the file, is this glsl multitexturing? I'm implementing this using fixed function pipeline.

Edit: Found some other articles that might help, had to think of a new phrase to find it. It might just solve the problem.

Edit2: I think I solved it, I can see the two textures now show up.
The problem was that I only activated and set glTexCoordPointer once.

Yeah, sorry, didn't catch that you were doing fixed.

[serengeor]

Yeah, sorry, didn't catch that you were doing fixed.

It might come in handy in future, now I'm only implementing the fixed function pipeline stuff. Thanks anyways

How I wish I can learn same as you do soon.

Just starting to crawl for studying on how to make all this.

Learning opengl is not really hard, just sometimes it gets tricky with documentation.
Must read every line of it. Miss a few lines and it can become head pain trying to figure out what is wrong with your code.
Having a good book is also a very big plus. Also it might be good to study some other sources to see how things can be made.

Have you tried to texture a simple quad to see if the problem is the TGA loader?

tga loader might be buggy for alpha textures, can't imagine why though as it is just additional alpha value at the end which is basically left untouched. Multitexture blending however works now, though I need to tweak it a bit.

Edit: The tga loader was indeed messed up a bit, I've fixed it and now it seams to load textures with alpha channel also ok.

very well
