Substance Painter to Marmoset Toolbag 2 workflow needed

[Lord Pelaxus]

I've been playing with SP and finally wanted to export my work to Marmoset Toolbag 2. Now i have these maps:
-diffgloss
-diffuse
-height
-metallic
-normal
-roughness
-specular

There's not enough slots in MT2 to put every of those maps. I did my best with standard, dota and Unreal4 template but still i don't know where to put exactly diffgloss, height, metallic and roughness. I did my best but maybe someone could straighten things up a bit...

This is my final results of experiments (left is Dota, right is Unreal4 template):

If anyone have good tips or tutorials please share!

You only need diffuse, roughness, metallic and normal. And also your raw baked AO. Put roughness in the glossy slot and invert it.

The rest is unimportant for marmoset. The diffgloss map for example is the same as diffuse except there's the roughness map in the alpha channel. Specular is extrapolated from diffuse+metal+roughness. They maybe useful for other engines but for marmoset you don't need them.

Hi,

Another tip is to set the refleciton to use GGX BRDF. Marmoset was using Bling/Phong and have changed to GGX which is what Substance and Unreal Engine use.

Cheers,

Thanks for tips

So roughness goes to Microsurface/Gloss Map or to Reflectivity/Refractive Index? And where exaclty should i put metallic map? Reflectivity/Metalness Map?

And can i use any of those maps for occlusion or cavity maps?

GGX only is for Reflection and Secondary Reflection.. still there's no slot to put any map there.

I did this experiment but it still doesn't look as 'juicy' as in SP:
