The ShapeMap that ships with Max 2017 will throw an exception when used in a scene. Tested with Corona 1.5.2.
The situation is exactly the same like with the TextMap (see
https://forum.corona-renderer.com/index.php/topic,14790.0.html)
If you start with a fresh scene, create an object and a material that uses this map and the shape to control the map, it will not render and throw an exception instead.
But if you load the attached scene, it will render fine the first time but throw an exception when rendering again after that.
Please make sure the map works fine. It's a great addition to the texturing toolset and needs to work with Corona.
