So from LDD you can export an .lxfml file, this file is basically a text file that contains all of the information about the model, what bricks are used, what colors they are, what their transforms are. My script reads the lxfml file, imports and places bricks from my library (which is populated by bricks I have set up/modeled manually) and assigns the brick with the correct material that is also made via the script based on the lxfml file, as well as some options given to the user of the script: (Arnold vs Redshift vs Blinn material, normal maps for the logo and bevels on or off, and dirt/dings on the bricks can also be toggled).
I'm not showing off the dirt part though as my current dirt maps look terrible and completely unrealistic, and still needs to be messed with.
If you'd like I can send you a copy of the script to look at. Since I'm using a student version of Maya I'm pretty sure I can't sell any of this work even if there was a market, so I was planning on making it open source at some point anyway.
Edit: btw @aquamorphproductions I'm not sure if you noticed, but I'm using your face decal on the mermaid, I credited you on the youtube video itself, but just wanted to say thanks here as well!
