Title: Try to find a solution to this kind of problem: bump map artefacts..
Post by: Stefj on February 15, 2017, 02:39:02 AM
Hello,

Since now several weeks, i try to find a solution to this bump map problem.... but no solution !  :'(
my bump map file from photoshop is very clean ( made by my hand with photoshop / 300 DPi - RVB 32 bits - 1/4e scale )...
i tried to make more smooth gradients, added noise, but it changed nothing....
( i also tried with more or less contrast / levels / luminosity / resolution and scale.....)

is it a keyshot bug with bump map ?

Hi Stefj,

It seems like your Bump Height  (Hauteur du bosselage) is at a very high value at -10. Do you still see the artifacts as you lower the value?

Try saving as PNG or TIF and resolution of around 2000x2000. If that doesn't seem to help, please send to my attention: support@luxion.com
