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… -
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… -
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… -
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… -
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? -
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? -
(Maya) Is it possible to covert cubic curve to linear curve
To Maya gurus out there. is it possible to convert cubic curves to linear curves while keeping the cvs intact. Without changing the positions of the cvs? (solved) Solution is to use rebuild curve with Uniform, linear, cvs check on. There are occasions that it didnt work perfectly, but it wokrs 90% of the time. -
linear workflow in Maya with mia_material
hi guys. so basically I'm newbie in 3D, started last year with zero experience in digital art (including photoshop), spend a whole year focus on modelling, this year I want to start to learn about texturing and rendering. Recently I learned about linear workflow rendering in Maya. I'm rendering a copper metal object with… -
How do I convert sRGB to linear in Photoshop?
Anybody know a quick way to convert sRGB to linear in Photoshop? I was looking under color settings but I'm not seeing any options. I'm asking because in UE4 there's a checkbox to make a texture sRGB and when you untick that box, it becomes linear. I'd just like to be able to do this outside of UE4.
