Title: CoronaDistance improvement - Use shape in Raycast mode
Post by: lupaz on 2024-03-09, 17:49:44
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.

Here's a discussion on Stack:

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.
