Color management

Sure. So I am creating most of my materials in Substance Designer (dirt, rocks, moss, carpet, tile flooring, tree bark, etc) using the sRGB IEC61966-2.1 color space (as opposed to "linear") then exporting those materials into Unreal. Same goes for the artists using Substance Painter, often using those same materials as a starting point. This is necessary for the lighting in Unreal to work properly. If we are doing any photoshop work, even those textures are processed through Designer for color correction.

I am exploring ways to blend these materials, as well as possibly authoring materials from photos, dynamically and nondestructively. Sampler seemed to be the ideal candidate for that task, being its already in the substance family and has very similar tools.

Unfortunately, Substance Sampler doesnt seem to have the same color space viewing options that Designer and Painter do, making it incompatable with my work flow. For example, the dirt I made in Designer, which is a light tan color shows up as almost chocolate brown in Sampler. When I tried to blend that with some of the stock leaves and rocks available in Sampler, they were very bright in comparison and just didnt work together.

My tech artist could probably describe it in more detail, but thats the gist.

Hopefully thats useful.
