Author Topic: FXmap pattern | displacement & normal map  (Read 4661 times)

Hi all,
I'm sharing my research on FXmap.
To better control the relief on my substance maps, I needed to do what follows.
(for displacement and normal map)
I use my modeler for the "gif displacement". All maps are currently 8 bpc.


square
8bpc | size 0.75 | displacement elevation 2.5




disc
8bpc | size 0.75 | displacement elevation 2.5




paraboloid
8bpc | displacement elevation 5




bell
8bpc | displacement elevation 5




gaussian
8bpc | displacement elevation 5




thorn
8bpc | displacement elevation 5




pyramid
8bpc | displacement elevation 5




brick
8bpc | pattern specific 0.5 | displacement elevation 2.5




gradation
8bpc | size 0.75 | displacement elevation 2.5




waves
8bpc | displacement elevation 5




half_bell
8bpc | pattern specific 0.5 | displacement elevation 5




ridged_bell
8bpc | displacement elevation 5




crescant
8bpc | displacement elevation 5




capsule
8bpc | pattern specific 0.5 | displacement elevation 1




cone
8bpc | displacement elevation 5











suggestion for allegorithmic
I think it will be great to have a tube pattern to make fiber and other stuff.
(this map its a 8 bpc screenshot of cylinder in my modeler)

tube
8bpc | size 0.75 | displacement elevation 4







curious result with paraboloid 32 bpc
When i use Substance player for export paraboloid in hdr file (32 bpc)
(not possible to export in hdr file with Substance)
I have another result, a half sphere!
(result usefull to make tube but not supported by Substance)





with substance viewer  (tesselation shader)
i have the same result like 8 bpc

Hey, good job !
Regarding the "curious result" with paraboloid and HDR files, I suspect the code we use to handle this file format in the player applies some sort of gamma correction, which is almost like taking the square root of the luminosity (typically taking it to the power 1/2.2, whereas the square root is 1/2). Since the formula for the paraboloid is 1-x²-y² and the formula for the half-sphere is just the square root of that, that may explain what you are observing.

thank you,
and thank for the explanation  :)
