View Full Version : Texture arrays and framebuffer objects

05-25-2012, 02:49 PM
I'm switching from regular 2D textures to 2D texture arrays. Texture creation and look-up in shaders works fine but I can't seem to get them working with fbo's.

Before, I've used glFramebufferTexture2D to attach a texture to a framebuffer:

glFramebufferTexture2D( GL_FRAMEBUFFER, attachmentIndex, GL_TEXTURE_2D, texture->id, 0 );

Now I'm using glFramebufferTextureLayer to attach a 2D texture array's first slice to a framebuffer:

glFramebufferTextureLayer( GL_FRAMEBUFFER, attachmentIndex, texture->id, 0, 0 );

The framebuffer is reported as being complete but the textures remain black. Am I missing something?

Thank you!

edit: tested on both ati and nvidia (latest drivers) with the same result.

Shaders please.
