I managed to take a look at GLSL and multi-texturing for a few minutes. Here's what I found:<br><br>1) ARB_fragment works exactly as expected with multiple texture units in GEM<br>2) GLSL does not work with the same GL setup commands in GEM
<br>3) Apple's ShaderBuilder does not work with Anton's shader nor any example shaders I tried with multiple textures<br>4) Shader builder works exactly as expected using ARB_fragment<br><br>This is with a G5 and Nvidia GPU. I won't get back to this until Monday, but I suspect that some setup calls need to be updated or changed to match what the drivers want in order to access multiple textures.
<br><br>For what it's worth, I only use ARB_fragment shaders in my own work. They seem to work better and more efficiently. I can post some shaders next week if anyone is interested.<br><br><div><span class="gmail_quote">

sorry. let me clarify. long work day does not make me clear.<div><br></div><div>switching texunit switches the textures. however, mixing only occurs between unit 0 and unit 0. Not between unit 0 and 1.</div><div><br></div>
<div>this is with Cyrille's patch.</div><div><br></div><div>Thanks.</div><br></div></blockquote></div><br>
