[REQ] Fix gradient lines in the sky

Good luck with with your gradient line work
I did my sky work in "SkyPS_SH5" shader file, very experimental
as I do not really know how to work with shaders.
see here
// 1. base gradient, from top to bottom
float heightRatio = (pow(In.eyeDir.w / 992.0 , g_skyBottomColor.w)) * 1.3 ;
color = lerp(g_skyBottomColor.rgb, g_skyTopColor.rgb,heightRatio);
I added "* 1.3" hope you will have a better luck

thanks, I will do my experiments

I am sure I asked about this in some other thread, but does anyone know if it is possible to use a real 16 or 32bit HDR texture as input?

As oppossed to the regular LDR 8bit textures.

The sky in SH5 doesnt use textures, it is just rendered using colors.

That is the scy object, maybe somebody can make it smoother??

[Decoman]

Does it matter? I can't imagine that that this coarse polygon mesh would cause the banding I've seen.

Maybe between one ring and another because of different angles of ligtning or something...?

Yes, that is the place where the sky gradient is generated.
SH5 used in contrast to his predecessors for the gradient not a texture.

The pixel shader generates here a color for each pixel in dependence to his height in the sky. A linear interpolation ( lerp() ) between top and bottom color values is used. The input values comes from the EnvColor_???.cfg's
