Avoiding Material Definition "Expansion"

November 22, 2010

Is there a way to avoid custom material definition "expansion" (tried material property editable="0", but obviously this obviously does not prevent definition expansion) ?

I don't know when and why it happens (maybe on save) but initial definition in custom library *.mat file


<material name="mesh_auxiliary_base" parent="mesh_base" editable="0">

   <!-- states -->
   <state name="auxiliary">1</state>
   <state name="material">0</state>

   <!-- auxiliary shaders -->
   <shader pass="auxiliary" object="mesh"
           defines="BASE_AUXILIARY"
           alpha_test_defines=",ALPHA"
           material_defines=",MATERIAL"
           auxiliary="1"
           vertex="core/shaders/meshes/vertex_base.shader"
           fragment="<customer_shaders>/fragment_base_auxiliary.shader"/>

   <!-- bindings -->
   <bind object="mesh_dynamic" to="mesh"/>
   <bind object="mesh_skinned" to="mesh" defines="MESH_SKINNED"/>

   <!-- textures -->
   <texture name="Material" unit="2" pass="auxiliary" material="1" filter="bilinear"><customer_textures>/mesh_auxiliary_material.dds</texture>

   <!-- parameters -->
   <parameter name="auxiliary_color">1 0 0 0.75</parameter>

</material>

gets expanded to

<material editable="0" name="mesh_infrared_base" parent="mesh_base">

Create your own material library with such header: <materials version="1.0" editable="0">. With editable="0" flag this library can't be overwritten.
