Hi eric, so to get to the materials list in SimLab like Burr is talking about, go to the Materials menu at the top of the window and pick "Manage Scene Materials". Then the "Scene materials" panel will pop up and it will have a list of materials in it which will match the styles list that you had in MoI.

Then to edit any material, make sure the properties pane is open and click on the material and you can change the material's property. If you do it that way you should be able to retain your styles/layers structure that you had in MoI and not need to worry about the object names at all, that's a separate channel of organization information from the materials list.

Hopefully that all makes sense.
