Best way to create Diffuse-Specular PBR textures from Albedo-Metalness?
Hello, I have a few models with PBR textures that use the albedo-metalness workflow, and I am trying to create the diffuse-specular textures from them. I found a tutorial on Marmoset, and many of the textures look right, but for some of them the specular reflections seems to be very high. I don't have Photoshop, so I'm not… -
Re: Best way to create Diffuse-Specular PBR textures from Albedo-Metalness?
Maybe my workflow is wrong. I don't have a Photoshop license, so I've been doing this with GIMP. This is what I am doing: Diffuse Map: * Load the albedo map into GIMP. * Drop the metalness map on the bitmap window (it get's loaded as a new layer). * In the layer stack's menu select Add Layer Mask. Pick Grayscale copy of… -

I'm rendering this on an application I'm developing, and I needed to know what was wrong, my workflow or my shader. I have added that #383838 (0.22) minimum specular color to my albedo-metalness shader and now I get the same result with both workflows: Albedo-Metalness-Roughness: Diffuse-Specular-Glossiness: It is a bit… -

That tutorial explains how to create albedo-metalness textures from diffuse-specular. -
Re: Best way to create Diffuse-Specular PBR textures from Albedo-Metalness?
Not really. The first tutorial basically tells you to identify in your textures what is metal and what not, and paint it black or white. There is no workflow to do it as in the albedo-metalness to diffuse-specular tutorial. Yes, I inverted the roughness textures to get the glossiness textures. Thank you guys! -
Re: Best way to create Diffuse-Specular PBR textures from Albedo-Metalness?
Yes, I was a bit confused too... I know everything is shiny, but a minimum of 0.22 seems too large! Here are the texture maps: Albedo: Metalness-Glossiness: Diffuse: Specular-Glossiness: And this is the workflow I used to generate and combine the texture maps: The model and the other maps are from the Grindstone free… -
Re: Best way to create Diffuse-Specular PBR textures from Albedo-Metalness?
Yes (ish)TM, everything >170 srgb is metal, fill with white. Everything < 170 is 56 srgb therefor black. -

Wait what? Can you post your new texture maps? -
Re: Best way to create Diffuse-Specular PBR textures from Albedo-Metalness?
Couldn't you generate a mask based off the spec values? (And maybe include a slider or two to adjust the transition) -
Re: Best way to create Diffuse-Specular PBR textures from Albedo-Metalness?
Well, I wrote the tutorial so I'm pretty sure I know what it covers. There are sections that explains how to go both ways. http://www.marmoset.co/toolbag/learn/pbr-conversion#metaltospec http://www.marmoset.co/toolbag/learn/pbr-conversion#spectometal If after reviewing it again, you're getting caught at a specific point,…
