<p>created</p> <p><b>New page</b></p><div>Material IDs are used to split a model's surface into multiple [[Material]]s. <br /> <br /> Normally a model can only use a single material. However a number can be assigned to sets of [[Polygon]]s which each correspond to a particular material.<br /> <br /> When the surface is split to use different materials, this does not create a visible split on the model. However a [[:Category:GameEngines|game engine]] must duplicate the [[Vertex|vertices]] along the seam, which increases the vertex count of the model in-game. These are called &quot;material splits&quot; (see [[Whitepapers]]).<br /> <br /> ----<br /> [[Category:Glossary]][[Category:Rendering]]</div>
