Maya

This Script converts all Pixel's of an Image into Primitives. The Type of Primitive can be chosen by the User.
The Alpha Channel provides the Height Information and can be manipulated as well.

Just Copy the Content of the Script into Maya's Script Editor and execute it (Crtl-Enter).
Use MMB on selected Text and drag it out of the Script Editor into a shelf.

Current Limitation:
Just quadratic Image Ratio is supported! (1:1) Example (60x60 or 80x80 or 112x112 Pixels etc...)

Next Release will support all Kind of Aspect Ratio.

The Script is pretty Brute Force. Will work on some Speed Performances (Instances, Only One Material...etc)

That's it...

Have Fun!
