Is it possible to select multiple nodes in Model tree?
I would like to change a certain a numbers of node to materials, but so far i do it one at a time. Is it possible to do otherwise/smarter?
It is not possible to change the function of multiple nodes inside of the model tree. However, what you can do is create a material group and add put all the nodes inside of that group. You can multi-select by holding shift and drag them inside of the material group node. This will effectively change them all at the same time.
