I've just rendered my first image in LuxCore and I'm quite impressed with the results

I have a problem with ceiling and grain on wall shader, so I would appreciate any suggestions.

Really nice start

I have a problem with ceiling and grain on wall shader, so I would appreciate any suggestions.

Can we see your ceilling shader node ?

what is your clamping value ?

Render setting ?

Here are my settings (which are pretty default, except from increased adaptive strenght) and ceiling and wall shader node.

Ok !

Can you try to render at a smaller resolution ( for fast preview) with Normal map disconnected and show the result ?

I disconnected normal map, but result is the same.

Changing wall and ceiling shader to standard Matte Shader without any image maps and environment to flat white colour also didn't help...

The mesh itself wasn't modeled in Blender, it was importet from .fbx, so I'll check it out later.

try to check for a double coplanar faces or some normals broken...

switch to cpu if the problem disappears.

To solve Shading Issue either:

• Set the object Shading to Flat.

• Check Normals 'Auto Smooth' on, set prefered Angle (if grayed out, most likely since it's imported fbx, Clear Custom Split Normals Data)

• Add support Edges.

• Post a file with only the corrupt object in it.

Set the object Shading to Flat.

This helped
Thanks to everyone!
