Blender 2.62 was released last week. You can find it at http://www.blender.org/development/r...s/blender-262/
There is something in the release notes about bump mapping that caught my attention but I haven't followed it up yet. The exporter seems to work ok.
Perhaps if anyone spots something of particular interest to Trainz content development they could post it here.
I Hope To Make Trainz Content Because Of Tomix's Tutorial.
