First, could you let me know if you've confirmed this as being plugin-related, by trying to reproduce it with/without the plugin loaded? You can prevent the plugin loading using Preferences > Extensions in SketchUp. If it only happens when the plugin is loaded, then:
- Which Arroway .skm Material do you mean? Jason has made a few different material collections, so please give me a link to show exactly what you are referring to. I assume the collection has more than one material -- is the problem specific to one, or does it occur with any material in the collection?
- Please clarify what you mean by "When applying materials I produce a bugsplat." Does this literally mean, when you are applying them, and if so, how are you applying them: using SketchUp's tools, using the "Assign to selected entities" button in the plugin Scene Manager > Materials, or by some other means?
