It's me or the Metallic map don't look the same in unity 5 ?

[Warsoul]

Look like my metallic map ins't exporting correclty. My model look like full metal and a way too much glossiness. What i do wrong ?

Are you using hte proper export and normalize settings in painter?

Unity uses its own PBR setup, painter supports it but there are some setting you have to set.

Are you sure then it's metallic and not roughness?

[Warsoul]

I use Unity 5 ( Standard Metallic) export settings. Nomalize ? What you mean ? Normal map ? I export in .png 16 bit

Unity usies a special PBR not the standard metallic roughness that others use.

I know, that's why i use the Unity 5 ( Standard Metallic ) like he said, i need to add the occlusion map like him. It look like my reflection probe is the issue but i'm not sure.

How i can assign different material for substance painter with Zbrush 4r7 ? I tried many ways but Substance recognize only 1 Default material each time. I unwelded all my polygroups and assigned each one an different material but still not working.

You dont need unweld polygroups, you can use MatID.

[Warsoul]

MatID with Zbrush 4r7 ? How ? I tried; never worked.

OOh my bad when you said standard i took it to mean you were using the standard PBR settings.

Hi,

There are also many differences in the shader Unity uses. They are using a different BRDF which causes a big difference. We are working with Unity for the 5.3 release to ensure a much closer match. Unity 5.3 will now be using a GGX BRDF.

How i can fix this issue with Unity 5.2 ?

Can you post a screen shot of the differences you see? There shouldn't be a difference in the map itself, but the Unity shader in 5.2 seems to render a much more glossy appearance. Its not an issue of the metallic map, but more of how the smoothness is interpreted.

[Warsoul]

Exactly, it look a way too much glossy. I have to turn off my metallic map and use the sliders to fit an better result. Can i scale down some value in my metallic map to fit an better result ?

Its not the metallic map. The issue is the BRDF and the way the roughness is interpreted. You should use a levels to adjust the gamma of the roughness. You can do this by creating a standard layer at the top of the stack and add a levels effect. Set the layer to target the roughness and then set the blending mode to pass thru. Then add the levels and adjust the gamma.

Thank you
