Okey, I''ve two questions about blending. First I''ll tell you about the code. I have made a milkshape ascii loader, and a alpha-bledning function in it. But it''s damn difficult to get the blending right. As milkshape has two 24bits textures for alpha, instead of one 32bits, the code gets more complex... I think. Anyway. First I load the the texture and the alpha texture. Then I use blending on them, and it works but still a problem occurs and I can solve it.
Here''s the code, ofcourse it''s more to it, but this is the part I''m wondering about..
for (l = 0 ; l<2 ; l++)
{
glEnable(GL_BLEND);
if (l==0)
{
glBlendFunc(GL_DST_COLOR,GL_ZERO);
material.texture();
}
if (l==1)
{
glBlendFunc(GL_ZERO, GL_ONE);
material.alphatexture();
}
}
The things that dosent work correct is shown below in the screenshot. Pic 1 and 2 displays two trees. Since I removed the texture on the ground, it''s not clearly that the blending works, but it does. Well, it works with the ground but not with another blended tree. When overlapping each others the first tree''s blended parts makes the second tree''s parts invisible. Yeah, the screenshot shows it and I hope you understand what I mean. And pic #3 shows fog in blending. I read that it''s hard to make it work together, but it must be possible since many games uses it, so does anybody know how?
I need to solve this so any help and ideas is very helpful to me.
