Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Severe issues with built lighting. Quality change has little to no differences

As you can see in the image below, the lighting is totally wrong, and I don't understand why, is this an engine issue, or do I have to change some settings to get it to line up properly, this is all in the third person default project, and yes I have tried remaking the project and even looked at the other templates, and they have the same issue.

Thanks for any help.

EDIT: I accidently posted this in the wrong area before, X-POST

You need to increase the lightmap resolution of the surface. Increase the value if it is a static mesh, decrease if it's a BSP to get higher resolution.

Cool, thanks for that It was driving me mad, would you happen to know why you have to lower the res for BSP yet increase it for static meshes?

I don't know why BSP's work like that, but it doesnt matter. You shouldnt be having BSP's in the level when your project is finished anyway(for performance reasons, and they dont look as good as static meshes.)

It seems that on BSP the number you are entering is how many pixels there are per X and Y world units. So at 1, there will be 1 pixel every 1 unit. At 64 there will be one every 64 units etc.

With a static mesh you are setting the total lightmap size of the entire mesh. I agree it is kind of confusing but has to do with the nature of BSP having no unwrapped UVs and having better support for scaling of BSP sizes etc.
