Hi,
I'm implementing deferred lighting. My models contain several texture layers including:
Diffuse
Alpha Map
Gloss Map
Specular Map
Dirt Map
Shadow Map

So I should render these layers to 8 color buffers using FBO:
Position
Normal
Diffuse
Normal Map
Alpha Map
Specular Map
Dirt Map
Shadow Map

I also need to output the scene to another buffer. So I need 9 out qualifiers.
My old graphics card (Geforce 9600) supports 8 out qualifiers. So if I try to output another out qualifier, I get this error:

error C5041: cannot locate suitable resource to bind parameter "myVec48"

How can I solve this problem?
