Title: Displacement values >1.0 and <0.0 produce geometry bugs
Post by: vicnaum on 2014-09-04, 20:28:40

The thread https://forum.corona-renderer.com/index.php?topic=5104 led to this bug:

1) Camera subdivision doesn't take displacement map values >1.0 into account:

Noise Map: Output 10.0, Corona Displacement: 20cm
(http://www.naumik.com/temp/scr4/20140904-805-123kb.jpg)

Noise Map: Output 1.0, Corona Displacement: 200cm
(http://www.naumik.com/temp/scr4/20140904-351-121kb.jpg)

2) Displacement map values lower than 0.0 just cut:

Noise: Output 1.0, RGB Offset: -0.5
(http://www.naumik.com/temp/scr4/20140904-id9-667kb.jpg)


And please don't ask why I did that... Some generators (like PhoenixFDOceanTex) can have any values, not limited to 0.0-1.0.
Modifier "Displace" is working correctly with out of range (0.0-1.0) values. Vray is also working correctly with them.

Corona cuts <0, and re-optimises >1.
