Edit

A file with the VMDL extension is a content-side text file that the tools can compile to make a game-side binary file (VMDL_C).

When a model is saved in Model Editor Model Editor, it writes out the VMDL file with the new changes, and the tools notice the change and then compiles the model.

Element reference

Notes

  • The first line that defines the schema text is the same in every VMDL, it is not a unique ID for the file or anything of that nature.
  • Filepaths in the VMDL are always relative to the content directory of the current game.
  • Elements with Reference in their name can either be internal, or have a reference to an external file path.
  • A VMDL can be compiled without all the fields being present. This example will compile as a simple static prop:
<!-- schema text {7e125a45-3d83-4043-b292-9e24f8ef27b4} generic {198980d8-3a93-4919-b4c6-dd1fb07a3a4b} -->
CVModel CVModel_0
{
	CVmeshList m_meshList = CVmeshList
	{
		CVmesh[] m_meshList = 
		[
			CVmesh
			{
				string m_meshName = "test"
				string m_meshFile = "models/test/dmx/mesh/test.dmx"
			}
		]
	}	
}

Larger example

An empty VMDL file looked like this:

<!-- schema text {7e125a45-3d83-4043-b292-9e24f8ef27b4} generic {198980d8-3a93-4919-b4c6-dd1fb07a3a4b} -->
