sRGB/gamma/color whoes, conversion from PSVR to CV1
Ok this may seem a bit "unusual" question but, I am working on a title currenty on work for PSVR ( PS4 ) and currently having it working as well on PC / CV1, all in house propietary engine so "all cod...
So "OK" there is the thing, I set OVR_FORMAT_R8G8B8A8_UNORM for the ovr_CreateTextureSwapChainDX() in place of OVR_FORMAT_R8G8B8A8_UNORM_SRGB, then I added a "final shader" between my last rendering and pEyeRenderTexture[the_eye_index];
So I tried "a bit of this and that" from just trying to touch brightenss/contrast ( linear transformation ) to manually apply a simple function gamma correction ...
Nothing seems to work "good" enough, it seems as soon as you start just using a bit of "amplification" (i.e. for example result.rgb = input.rgb * contrast; you get lot of match banding in "low colours".
The thing is to me looks like sRGB should be "the correct thing to go" but it's like the CV1 has some sort of "strange range" of colours like "too dark is too dark", "too white is too white" there's really "something odd" I don't get what's going on.
It's really frustrating I have two things side by side and I cannot make the look similar, thing is I really don't know what is the nature of the problem I am seeing.
Anyone knows or want to talk about ?
Cheers.
