problems with archviz lighting

hi i changed a value but now i can´t fix it anybody can help me where i should to look

thanks

Hi,
I recovery a backup and i could fix it so i haven´t known what it happens, now i have a shadows problem these element (wall and ceeling) are ue4 plane and i try to change the light resolution but its the same, i have another plans in the scene that works ok, i don´t know if it´s for the physics scale or what it´s… it´s calculated on preview mode now i tryn with medium.
I have another problem with the opened window, it has the same properties than closed windows but it´s like if it was iluminated.
sky light it´s a hdri static
light source it´s stationary

thanks

ok i discover that noise appears when i reduce the static lighting leve when more i reduce more appears (talking in preview mode) i think i have to supposed that ot has to be normal, now im building a medium build

@cwm83

For the walls and ceiling, have you tried adjusting the lightmap resolution of the meshes? Hit Alt-Zero to show lightmap density. You want thing to be green (or even red, if you don’t mind longer light build times). Look for ‘override lightmap resolution’ in the details panel when selecting the mesh to change it.

As for the windows, do they all have the same mobility? If one door is set to movable and the other set to static, the movable one will use dynamic lighting and will look different from the static one. Another possibility, depending on where the geometry came from originally, is that the normals of the mesh are somehow messed up. You can try looking at the normals in the Buffer Visualization view mode: https://docs.unrealengine.com/en-us/…rvisualization The two doors should have the same color. If they don’t, you can try using recompute normals from the mesh editor.

i add a picture of normals… you are talking about this, aren´t you? the same color…

Hi!

It doesn’t matter if it’s red: could be still low!! Unreal was designed to make games and not archviz projects…
So you might not even have a problem if it was a preview build…
Your lightmass settings…
As low as you go with your indirect lighting scale as much detail you’ll get (if you set a high enough lightmap resolution)… so if you want realistic result I’d go with 0.1 - 0.15
60 indirect bounces are unnecessary! After 10 it’s just random and can cause weird results…
I think your smoothness is too high (default setting)! You’ll lose a lot of indirect shadow detail + can cause shading differences between objects with the same material… I think the best to go with is 0.6
Good luck!

im trying with these parameter
num sky lighting bounces set on 4
Do you know where i can study more about these parameter? talking about archviz… exterior/ interior etc…
also i upgrade a higher value for the resolution light map but on preview mode it´s the same i will check on medium

thanks

hi! i finish the medium build but i have still shadows problems… i understand if i upgrade to high production will be fix or put a higher static?

almost all of my interior walls are Cube from UE4, so i unerstand that the uv map it´s ok, but a lot of them are intersected…
the light its a movable spotlight
im going to upgrade light map resolution also…
i have a problem at the interior bathroom if i use a post process volume i get a very dark bath, does the light here come from skylight? im using a hdri… another thing that i dont understand why there are hdri with picture an another isn´t, is it important?, if i don´t use post process volumen the expossure auto adjust but i dont think it is ok

thanks for your help
