I have tried to find a way to apply and/ or change a shader for multiple objects. If you select them all and group them, you cannot drop a texture on the whole group. If you simply select a set of objects (without grouping them) you also cannot just apply one shader to all of them. Help? Another puzzler, why is it that you can only replicate ( and use a pattern to position) in the vertex modeler? The assembly room could use this functionality. John Jacobson
