CoronaDistance improvement - Use shape in Raycast mode

[lupaz]

Hi,

I was looking for a way to use a spline to generate a mask. The spline would be the boundary for the shape and it would be projected onto the object I need a mask for.

Currently with CoronaDistance you'd need to use a volume AFAK, which can be messy and you'd need to set it to not-renderable and show as box if you don't want to have an annoying volume.
It would be interesting if there was a mode in CoronaDistance that allows to use a spline in projection mode without having to actually extrude the shape.

3DS Max's ShapeMap is slow to render with Corona.

Meanwhile, the workarounds include either extruding the spline or using 3ds Max features such as the shape map or conforming geometry (which may or may not work...).

Wait, last time I checked the built in Shape Map only worked with a few primitive shapes like rectangle and circle but would not accept arbitrary shapes - has this changed?
Also, it always produced jagged results, its borders/results were noisy and never clean enough for me to bother using it.

I tried with shapemap and works really well, no jagged edges or anything like that, but renders much slower than coronaDistance.
