External meshes with external materials

[halaszlo]

Hi guys,
Can I define for an external mesh that which external material to use?
My example code is the following:

Code: Select all

	<include>
			<pathname>../Assets/Objects/Shared_IGMAT_001001/Material1.igm</pathname>
	</include>

	<include>
			<pathname>../Assets/Objects/Shared_IGMAT_001001/Material2.igm</pathname>
	</include>	

	<mesh>
		<external>
			<path>../Assets/Objects/Shared_IGMESH_001001/Mesh1.igmesh</path>
		</external>
		<scale>1.0</scale>
		<normal_smoothing>false</normal_smoothing>
		<name>Mesh1</name>
	</mesh>
	
	<model>
		<scale>1.0</scale>
		<mesh_name>Mesh1</mesh_name>
		<rotation><matrix>1.0 0.0 0.0 0.0 1.0 0.0 0.0 0.0 1.0</matrix></rotation>
		<pos>0.0 -0.560000479221344 0.0</pos>
		
	</model>
	
	<model>
		<scale>1.0</scale>
		<mesh_name>Mesh1</mesh_name>
		<rotation><matrix>1.0 0.0 0.0 0.0 1.0 0.0 0.0 0.0 1.0</matrix></rotation>
		<pos>1.0 -0.560000479221344 0.0</pos>
	</model>

So I have 2 material included and 2 model from the same external mesh.
How can I say for the models which material to use?
It seems to me that it is declared in the mesh, igmesh file itself and I can not modify it.

Indeed, material names are stored in the igmesh. But you can by creating material aliases, this will create a material of the same name than the mesh material, but which points on another material defined elsewhere in the igs.

Code: Select all

<alias_material>
   <current_name>Leather</current_name>
   <new_name>previewmaterial</new_name>
</alias_material>
