Hi all
This is my code for creating texture object:
Code:
glGenTextures(1, &tex_name);
glBindTexture(GL_TEXTURE_2D, tex_name);
glTextImage2D(GL_TEXTURE_2D, 0, GL_RGBA, tex_width, tex_height, GL_RGBA, GL_UNSIGNED_BYTE, tex_data);
'tex_data' is loaded from raw RGBA8888 data packed with zlib. It loads as it should, wich i've checked with a debugger.
This is my code for setting up texture before rendering:
Code:
glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
glBindTexture(GL_TEXTURE_2D, tex_name);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE);
I've attached a sample of what I've expected and what I've got. In the sample most of the texture in the bottom is pitch-black with 70% opacity. However openGL renders it as gray. This problem affects all of my textures I use blend with.
If anybody has any idea where the problem is, I would really appreciate the help.
Cheers
