Curvature weird behavior

[blackcrownvisuals]

Hello, been a while.
I ma porting a project from RS to Vray and I am a bit stuck with the Vray_CURVATURE.
Its behavior is kinda weird. I am used to curvature like A LOT and I am a bit lost here with the Vray one. No Convex / Concave to start with and I will not get no matter what I am expecting to get.
Anyone experiencing the same issue ?
I am running 18.5.633 / latest nightlies



Thanks

Hi blackcrownvisuals

"Radius" label is wrong - should be "sample spread"
Scale - distance from surface along normal at current point, where sample rays will be spawn
Sample Spread /currently wrongly named Radius / - a multiplier for sample rays distribution.
actual spread = Scale * Sample Spread
Trace Distance - multiplier for max distance ray travels after which it is killed
actual max trace distance = Trace Distance * Scale * Sample Spread

here is an video example to explain everything
green line - normal at given point
green point - point along this normal where sample rays are spawn
yellow lines - rays distribution
red dots - points where rays hit surface

Wow those are some very low level controls...
At least rename scale to surface offset or something.
