32bit textures

OpenGL OpenGL: Basic Coding

I think is must be possible to have 32bit textures since I can load in 32bit images and display them. However the issue is that when I texturise the images, I get a black colour where the transparent elements are.

I though this could have been the clear Buffer colour, but when I changed it, there were no improvements. I couldn’t see the red background behind the transparent elements.

What do I do?

Is your alpha blending enabled?

Is that “glEnable(GL_BLEND);” ?

yes along with this

glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
5

Does your texture of type GL_RGBA?
