before build
after build
Hey ted juhlin,
I have a few questions and suggestions that might help you find the solution to your issue.
Is walkway in your image a Static Mesh or is it a BSP surface?
If it is a Static Mesh, be sure the ‘Lightmap Coordinate Index’ is set to 1.
Is the Lighting Quality set to the Production level?
Have you added a Lightmass Importance Volume to your scene?
Let me know if you have questions.
Cheers,
Hi im new to unreal so where can i find Lightmap Coordinate Index, Lighting Quality, Lightmass Importance Volume and yes the walkway is a mesh the buildings are BSP for now.
Well, welcome to the community 
I would highly recommend having a look at our documentation, which will give you some really great information on how to use UE4.
Unreal Engine 4 Documentation
I use our documentation quite a lot to brush up on old information I might need some refreshment on, and to learn knew things!
The Lightmap Coordinate Index is located in the Static Mesh editor by double-clicking the mesh within the content browser.
Don’t copy the settings from this image, except for the coordinate index. The boxes I have highlighted are just some major points of interest when editing your Static Mesh.
Lighting Quality can be found in the dropdown arrow next to the Build button in the main viewport toolbar.
The Lightmass Importance Volume is an actor that can be placed in the world via the ‘Modes’ tab.
With that being said, whenever you come across an issue where you might not understand or need help. Don’t hesitate to post to our Forums or here on the AnswerHub. We have a very willing and helpful community.
Cheers,
none of them work i tried to but the Lightmap Coordinate Index to one and but the Lighting Quality on production at the same time and the walkway just go darker when the Lightmap Coordinate Index is on one i even tried to do all three of them at the same time. I also cant see build settings in the Mesh editor.
Could you provide me with screenshots of your Static Mesh editor open?
The build settings are expanded by clicking the dropdown arrow. Be sure to look carefully, as it can be easy to overlook settings and menus.
Can you reproduce this in a blank project so I can get this to occur on my end?
If you cannot repro in a new project, you can send me your current one so I can see what could be the potential cause of the issue. In order to send me your project attached you will need to zip up your Config, Content, and .Uproject files/folders only.
Then upload it to an external file sharing program like Google Drive or Dropboxx and share the link with me. I can then download and investigate the issue on my end. One guess I have is that you have scaled your mesh non-uniformly and the resolution for that mesh is too low.
Let me know if you have other questions.
Thanks,
and what do you mean with reproduce this in a blank project do you want same type of screenshot but in a new project?
By reproduce this in a blank project, I mean can you take the same steps you took in your current project, and reproduce the issue you are experiencing?
If so, you can provide me with the steps and I can try to get it to appear on my end. Since you are new to Unreal, I highly suggest taking a read over our documentation to familiarize yourself with the terminology and the editor.
I have highlight the areas which you will want to look at, and I am pretty sure your issue is that your Lightmap Resolution is set to 4.0 which is very low for a Static Mesh. I am assuming you converted this mesh from a BSP, which is why 4 is the default.
Change the Lightmap Resolution to something like 512 or 1024 since your walkway is fairly large.
Cheers,
it works now thank you so mush and i will read the documentation while i go. I used to study 3ds max in school so i know somethings, but thanks for the help.
