I’ve posted an update to the 3Delight/Blender exporter, hopefully fixing some problems that people have run into after trying the first released version. I’d only been developing this on my own system, so I guess it’s expected that for people on different platforms, with different configurations, it may not behave the same way that I assume it will! Thanks to everyone for the feedback letting me know about this.
I’ve fixed two main issues, one was with the way it interpreted and exported file paths on Windows. Many thanks to @vitos1k for spending several hours helping to debug this with me. Another issue is that on Mac OS X, the 3Delight installation only sets up the environment variables it needs, for use in the Terminal. This meant that launching Blender from an icon in the dock wouldn’t detect the correct 3Delight paths.
To fix this, there are two additional options – one method allows you to define the path to the 3Delight installation folder from within Blender (Render Properties -> Search Paths panel -> 3Delight Path), or alternatively you can force it to always use a specified folder by specifying the 3delight_env.txt file in the addon folder. However if you have environment variables properly set up, they will still take precedence. This is explained in more detail in the installation.txt file inside the addon package.
