I've been working on two more export capabilities of our TD Scripts Blender Add-on. Should be released this week!
The first update rebuilds the entire mesh in Touchdesigner using a DattoSOP. You basically have direct acces to the geometry by using the docked tableDATs. Other than the SopToDAT, you can alter the data in the tables and the geometry changes with it.
The second update exports a UV Map representation into TD. I always find the whole UV realm in TD a bit of a black box. With this script you can view how the UV's are laid out.
Couple small bug fixes, mainly overwriting issues, doubles etc.
Stay tuned!
