Substance Designer - problem with Metallic map in Unity

eldanu

Hi guys!
I'm learning Substance Designer
When I export the sbsar from Designer to unity the model is too shiny.
why this happens ? also happens with Substance Painter but I can solve with photoshop using the alpha of the map , but with sbsar files the textures are stuck and can not be edited.

Someone has this problem?

Or someone who can help me please, thanks!!

Would be really helpful to see the graph, but I think either the roughness or the metallic map doesn't come trough in the right channel.

Unity uses Spec/Gloss not Roughness/Metallic. I think they're inverted from each other. 

Make sure you're using Spec/Gloss if you're pushing it to Unity.

Unity uses the Roughness/Metallic, they have a shader for that, in fact I wouldn't use the Spec/Gloss workflow, especially as a beginner.

Ah, last time I used Unity it used spec/gloss and it would also explain the issue OP is having.

Hi guys. I put the graph. the strange thing is that if it looks good in substance designer in unity it would have to see in the same way right?
I suspect it may be a problem of my gpu. You know if there are problems between amd gpu and substance designer?
 Thanks!!

Unity (using 5.3.3f1) does not use metallic/roughness actually, it uses spec/gloss or metallic/gloss.

Their texture packing is downright stupid. Metallic has its own texture taking up full RGB channels for seemingly no good reason, and then they pack a gloss map in the alpha channel. The most inefficient way to possibly pack a texture. AO has its own slot. A++ all around to whoever determined that setup.

On top of all of that you have to gamma correct your gloss before import to get a proper response.

I would strongly recommend branching the Standard material to anyone using it in production to pack that better.
