[Substance Painter + Marmoset] - Everything way too dark in marmoset - (Need Help fast please!)

OccultMonk

Normally this probably should probably be posted in either the Marmoset or Substance Subforums, but they are a bit slow going and I need an answer fast.

I am trying to use Substance Painter for the Allegorithmic Beast Contest. But I Must be doing something wrong, because I can't get the textures or lighting to match. I try to increase the Sky in marmoset to 4x just to compensate for the dark textures, this again creates washed out results. So I have to compensate in the textures, making them lighter. Basically I am working half blind this way. I think there is something wrong with the interpretation of the Albedo. Like it is linear instead of sRGB. But if I turn it off I get washed out results.

I am using the same HDRI in both Substance Painter and Marmoset. I have set all the required settings for the Metal roughness workflow:

Substance Painter:

- Shader: PBR-Metal-Rough
- Maps Base NM, Color, Roughness, Metallic
- Same HDRI on Env Exposure 0



Marmoset: 

- Reflection Model GGX, 
- sRGB Off for Metalness, NM, Gloss
- sRGB On for Albedo
- Glossmap with inverted Roughness
- Same HDRI on 1

What are your Post Effects settings in Toolbag 2 in the camera options?
You may want to change the Tone Mapping function or the Exposure in there.

OccultMonk

Already tried that. Linear/Reinhard gives almost the same results. (Everything is on default settings):

I notice that the HDRI preview in marmoset appears much brighter/washed out compared to Substance, why might this be?

OccultMonk

I do not think so, All HDRI maps result in a too dark image (also the default marmoset 2 sky ones).

Bek

Ah, I just noticed it looks like your Albedo material setting in marmoset has a colour value (grey) — change that to white. That's what's darkening your albedo.

Thanks, I think that was it! I must have set that value at one point to render the model with only a NM, then left it at gray.

Bek

Yeah I think people expect that value to be overwritten by the supplied texture; which possibly should be the case as it's easy to overlook. On the other hand being able to quickly darken the albedo can be handy for previewing, similar to being able to adjust the glossiness slider (though being able to + and - would be welcome there, especially with inverted ticked).

I think I know, make sure you set the albedo color to white, even if you use a texture: the texture is multiplied by the color.
