Better Bumpmaps
Posted: Fri Dec 04, 2020 8:48 pm
If you load an image from a Z-Depth screenshot you usually see nasty artefacts in smooth areas from the greyscale levels stepping. I've added a better Bumpmap to Normalmap convertor that creates a smooth result in gently changing areas and a sharp result in more finely detailed areas.
The stepping effect was not great in Curvy 4, but it was really bad when I tried to use bumpmaps in other software - they much prefer Normalmaps and you can simply load Curvy's created normalmaps into other software for an instant render quality improvement.
This realtime screenshot of Curvy 3D 5 shows the new bumpmap tech on shiny plastic and worn metal. Without the bumpmap both spheres would look perfectly smooth.
