I have been working with background geometry and have run into a few issues. It would help if I understood more completely how it worked. 1. It seems that only solid shapes are shown... is that right? If I have an alpha blended object then it does not seem to show up. 2. You can't share appearances between background geometry and foreground geometry? Is that right? 3. Your geometry should be unit scaled (0..1) I am experimenting with moving distance terrain (3km to 20km) into the background geometry. To start I just set a transform to scale it down to be 0..1 and then I attach it to a branchgroup under the background node. Its not showing up, even though other geometry is showing up (sky dome for example). Is this because the transform is ignored and the actual vertices need to be be in 0..1?
