Substance Alchemist, is splatter filter working properly?

Hey everyone, should splatter work correctly at the moment? I created this rock atlas, but when connected to splatter, normal maps don't look right. I'm working with Opengl through the entire process. I imported rock into Alchemist as a sbsar file. Here are comparison images, hdri is facing same way in all programs, light coming from front of camera. Am I missing something here?

Designer

Alchemist



Shouldn't cyan on a normal map come from top side on all rocks?

Yes, It's not accounting for rotation. 
 No idea if it's supposed to work or not but since you've got designer you can make your own scatter or just use height maps and convert them later

There seems to be some kind of issue indeed, we're looking into it.

@Jerc thx! Just noticed though, it seems to be a problem with normal maps in general, not only splatter filter. I'm working with OpenGl, and the shadows should come from opposite side if I am not mistaken...isn't red channel also inverted?

Is Alchemist currently working only on DirectX, because material doesn't take into acount height modulation filter if I change Normal Format from DirectX to OpenGl?
