how texture coords in GLSL with state/in variables (not gl_MultiTexCoord0)

Jul 22 2013 | 6:19 am

How can I get the equivalent of gl_MultiTexCoord0 using the state or in variables for GLSL?
I tried:
in vec4 TEXCOORD0;
but it appears to always be zero or undefined.

I need to move away from using the legacy/compatibility variables like gl_Vertex and gl_MultiTexCoord0 so I can write more advanced shaders than GLSL 1.2.

I have been successful with other replacements. For example:
in vec4 POSITION; works to replace gl_Vertex;
param name="modelviewproj_matrix" type="mat4" state="MODELVIEW_PROJECTION_MATRIX" works to replace gl_ModelViewProjectionMatrix

Below is patch and attached is the needed shader. I see a black cube. It should be a cube with chili peppers on it.

On Windows, I isolated it to be only a problem with the texture coordinates. Windows supports the compatibility profile so I could do troubleshoot (Mac doesn’t support compatibility profile).

wow. forum software failure with code formatting and attaching a file.
Attaching the JXS as a ZIP file…
