Default lighting,Default Shader and GL Gamma/sRGB Lut

[pixo]

Hello guys,

After few tests it looks like the viewport have a display gamma of 1 , this is not really good cause you can't see what you will render.

We should be able to choose the display gamma.

If not , it means that we will have to color correct the textures when we will do the lookdev , which mean a lot of go and back with 2d and 3d package.

In production, since the guys that will publish the textures is oftenly not the lookdev guy,

it will most probably lead to problems, especially if there's a lack of communications which is frequently the case .

I noticed that the default lighting is "100", there's no decay so what does it means ? .

The value to get the same result as your default software when you put 1 as intensity is "50".

The default Color texture is GREY , this is not good cause the Color texture is multiply by the diffusion, this is probably why the default lighting is 100 to make look the grey as a pure white .

imho what we should have is:

-Remove the percentage , it doesn't mean nothing in 2012.(Especially for lighting)

-Default lighting to "1.0",better would be to control the light color.

-Default texture Color to pure white float (1,1,1) or 8 bit (255,255,255).

-Display gamma set at least to gamma 2.2, a little bit better would be sRGB, the best would be to be able to customize it, like Mari, to set the gamma manually or to select sRGB and the ability of a display 1d/3d LUT.

Cheers,

By the way here's how it's supposed to be for a lambert or "Default" shader with a color value as (127,127,127) 8bit in sRGB.See attached picture.

In the same time, in photo or even for 3d Rendering ,depending of the engineers the Grey is around 12% or 18% of the pure white float(1,1,1) , and the white around 70 to 80.

It means that the (127,127,127) 8bit as default color doesn't mean something, it haves meaning for 8 bit displace or bump.

Even worse the (127,127,127) 8bit it's pretty close to the photographic white.

@pixo: Better emailing this to Andrew...(If you didn't already)

@carlosa:What is the point of linking to a page about lathing??... this thread is about default lighting...its completly unrelated.

+1 here, be able to work in 2.2 gamma would be very very useful. i think some kind of viewport post process could do the trick.
