egg multi stage texturing question

[treeform]

I want to be able to load 3 images (via texture stages) into a single texture like thing. Some thing like this:

<Texture> Tex1 {
  "breeze-rgba.png"  
  "breeze-bstg.png"  
  "breeze-norm.png"    
  <Scalar> format { rgb }
  <Scalar> wrapu { repeat }
  <Scalar> wrapv { repeat }
  <Scalar> minfilter { linear_mipmap_linear }
  <Scalar> magfilter { linear }
}

That does not work but looking at

stage-name { name }

Specifies the name of the TextureStage object that is created to
render this texture.  If this is omitted, a custom TextureStage is
created for this texture if it is required (e.g. because some
other multitexturing parameter has been specified), or the system
default TextureStage is used if multitexturing is not required.

priority { priority-value }

Specifies an integer sort value to rank this texture in priority
among other textures that are applied to the same geometry.  This
is only used to eliminate low-priority textures in case more
textures are requested for a particular piece of geometry than the
graphics hardware can render.

There seem to be a way to do this. Maybe through?

combine-rgb { combine-mode }
combine-alpha { combine-mode }
combine-rgb-source0 { combine-source }
combine-rgb-operand0 { combine-operand }
combine-rgb-source1 { combine-source }
combine-rgb-operand1 { combine-operand }
combine-rgb-source2 { combine-source }
combine-rgb-operand2 { combine-operand }
combine-alpha-source0 { combine-source }
combine-alpha-operand0 { combine-operand }
combine-alpha-source1 { combine-source }
combine-alpha-operand1 { combine-operand }
combine-alpha-source2 { combine-source }
combine-alpha-operand2 { combine-operand }

But i am kind of confused on how to use this.

You don’t load 3 images into a single texture… you create 3 textures and apply them each to a single face. They are then applied in the order specified, each as a texture stage.

I don’t know if you use chicken but it fully supports this - apply multiple textures in Blender and they will all be applied to the face. It doesn’t give you any direct control over the operands, though it does interpret a few of the combine modes to allow for some level of intelligent mixing, plus has stencil support.

Thanks that worked!
