The trick is: By adding more objects afterwards with Join Geometry, or as in this example with Geometry to Instances, these inherit the materials of the base object. Here you use the original geometry, to which several materials were assigned in the Material Properties before, as a base. If you create geometry in Geometry Nodes, you have to assign several materials to it, which is possible by lining up several Set Material nodes and then selecting the respective slot with Set Material Index.īut this is not very flexible, because you would have to use many nodes in a row manually. This can be either the geometry containing the Geometry Nodes modifier, but also geometry created in Geometry Nodes. Therefore the node Set Material Index can only be applied to a geometry which has been assigned several materials before. The node Set Material assigns a material to a geometry.
