Shadows showing wrong on geometry

I’ve build a simple corridor just using basic in-engine geometer shapes. I’ve does similar things before loads of times and the basic lighting is usually fine. This time though the shadows being cast are all wrong. They look completely fine when I place the light but after building the look completely wrong.

This only seems to be happening since I updated to 4.4.1 from 4.4.0

Top is before lighting build, and how I want it to look roughly.

EDIT: Added bug tag as I can’t seem to replicate problem in pervious versions. Also I know I can probably fix this with properly designed assets in 3dsmax etc that have been lightmapped but that kinda defeats the purpose of having geometry in engine to do basic mapping out, additionally it seemed to have been working before just fine.

Increase the lightmap resolution of your geometry → I think with brushes you have to decrease it :slight_smile:

Yeah I had seen that commented on another thread, what I don’t understand is why is was working fine without changing the resolution before the update 4.4.1

Update: I’ve tried both increasing the lightmap res and decreasing it. I’ve also tried changing the light from stationary to static but with no difference.

have you tried LigthMassImportantVolume ?? or changing to Dynamic light ?

is right, you’ll need to adjust the lightmap resolution to get this working correctly.

On BSP you’ll need to adjust the LM resolution down. The default is 32 but adjusting to something lower like 16, 8, 4 will give you better results. You can go lower if needed. This is opposite of what SM LM settings are.

If you have a Static Mesh you’ll need to adjust the LM resolution for the mesh that is receiving the shadows and not the one that is casting the shadow.

Give this a shot and let us know if this works out for you. If not let me know and we’ll look at this further. :slight_smile:

@ As said a few comments up I did give this a try, and pretty much every setting inbetween with no difference. After some more fiddling it appears to be related to the fact its a corridor. It doesn’t happen it if expand it out to a room (square or rectangle) and it happens with every corridor of similar design. I can upload a drawing with size specs later if that would help (don’t have access to computer just now)?

Go ahead and do that and I’ll have a look to see if I can help you out with this. Adjusting the lightmap resolution is typically the way to go. BSPs can be finicky at times.

Thanks!

Hi ,

I’m going to mark this as resolved since I’ve not heard back from you in a few days. If you get the dimensions and want me to offer any other assistance feel free to post here to open it back up.

Thank you!
