<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve investigated further and believe I’ve found the problem but not sure how to fix it.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a constructor for a layered texture class where I pass it an image as the base layer. I set the texture mode and create a texture in this constructor for the base class. I also assign BASE_TEXTURE_UNIT to the sampler2D as an id
to bind the texture to it for the shader (thanks for this..).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I run a function called updateShaders() (which I’ve sent snippets of code for) at the bottom of my constructor class. If I access this base sampler texture in the shader, I get what I expect on the geometry.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Now, when I call a function to create a layer for this layered class (i.e. createLayer(some image, weight, etc..)) from the application, I create a texture from this function and I run the updateShaders() function again binding the BASE_TEXTURE_UNIT
+ 1 to my second sampler node and trying to bind it to the texture I just created.
<u>THIS is what’s NOT working properly</u>. When I run GPUPerf debugger, I see that the texture unit is assigned the correct #2, but the BoundID isn’t equal to the unit number. So when I sample from the texture in the shader, it’s just black because it can’t
see this new binding (assume no blending in the shader just an overwrite).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">To test this, I reconfigured my constructor to take 2 images instead of 1 image for the base and I forego the call to createLayer() in my application. Sure enough, the binding is properly set. Am I missing some kind of callback that should
force a rebind when I call updateShaders()?<o:p></o:p></p>
