Controling roughness (gloss)

[Izayoi]

Hi
I have to create a material which contain blurred and sharp reflections.
This is very similar to a simple window with mist on it



Is there a way to control roughness (gloss) with a map created in photoshop ? Any workaround ?

thanks

I think you'll need to merge 2 renders in post.
1 with roughness, 1 with reflections.

yep but i have a full animation to render.
So sad we can't do a so simple thing automatically   
Adding a super blend material to merge 2 differents materials could be an other good solution in future keyshot versions

No - it can't be done in KeyShot at the moment, the workaround is to do it in post...

This is a feature I've wanted for a while

just wondering if this can't be done with a decal ... ?

Else the gold-trick ... which consists of 2 planes very close to eachother.  The front one gets a rough finish with an opacity map that shows trough the 2nd plane in some places.  Then the second plane gets the mirror material.  This might work for animation.

yep the trick is to use Label. I put a texture map with the same color as my diffuse slot then made the specularity to full white. This give really sharp reflections.As you can see.
However i don't think this work for transparent materials.
I didn't test by duplicating my object, is quite heavy and keyshot will probably crash. 

I agree with you Biomechanic.
