Re: Gamma or Linear color space for diffuse-only game ?
When people talk about working in Linear Space, it means all inputs (sRGB or linear) are converted to linear, then all your blending and lighting functions are calculated in Linear, then the final output is converted to Gamma Space for display. -
Substance Designer: Linear vs SRGB output?
I came across some threads in the Allegorithmic forum that seem to imply that all maps except the diffuse/base are converted into linear. Was this only for the 3D previewer in Substance alone? I attempted to change the output nodes to different types (say base versus roughness), and they still exported out the same way. So… -
Don’t use gamma on normal maps
I shared this on LinkedIn, might help some people here too. Don’t use Gamma on normal maps Normal maps should be saved in linear color space, without color correction from Gamma or sRGB. A lot of game PBR texture pipelines use sRGB color space, which is fundamentally very similar to Gamma 2.2. It’s so close, they’re pretty… -
is 4% reflectance value is in linear or srgb?
Here is one of those confusing topic again. I remember I've asked long ago how come using substance designer to convert from metal/rough to spec/gloss the spec value is grey. And someone has answer it is because all object has spec and its 4% in linear and 2% in srgb (or the other way around) Assuming my render engine will… -
Formula to convert 0-1 linear into sRGB
Hi! Sorry if that was asked a lot. I need a formula to convert 0-1 linear(which is used in material sliders like 3ds Max,...) like 0.7 into Photoshop sRgb(0-255), what is used in PS histogram. I need that for non color maps, like roughness. I don't know if the correct formula is x(linear)*255, or do I need to factor in… -
sort of a dumb question about linear workflow...
I have been learning how to use a linear lighting workflow in maya. Does anyone know if any of the stuff concerning gamma apply when lighting in a game engine? From what I've learned, linear workflow helps you obtain physically correct renders by keep it in linear colorspace rather than srgb- Does anyone know if something… -
Re: Help with the Equation for converting Gamma to Linear.
Note that 'linear' in this sense is that a certain 'x' value is mapped to the same 'y' value. It means it forms a "straight line graph." That 'linear' has no relation to the data type used to represent the colour value -- whether it's represented by a normalised floating point value (0.0 ~ 1.0) or by an unsigned byte value… -
Re: PBR - Linear and sRGB
Basically linear = no gamma correction, sRGB = gamma correction. Pretty much any photo or image made to view on a monitor is gamma corrected, basically a linear image is telling your display to increase the brightness of each pixel in a very constant and even way, but when you do that, the actual results you see on the… -
Camera RAW to linear exr?
Do somebody know a program where It's possible to export full range of pixel brightness from a typical RAW camera makes to a linear exr file? Maybe linear 16 bit tiff or something without typical clipping? Not in Adobe Lightroom it seems. Maybe in some alternatives? -
Working Linear Unit not saving
So I'm trying to get Maya to save my working linear unit as centimeters as default in my preference. However when I save my preference close Maya, and open it again. My working linear unit is back to meters. Any ideas on why this is happening?
