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"

How do i fix lighting for a static interior in 4

This is what the lighting looks like once i build it in unreal

I'm not sure if this is a problem but this is what my model looks like in my maya scene. I'm curios if those lines/gaps are what is causing the weird shading in unreal. If those lines are the problem is there anyway to fix it in maya? All my walls were snapped and combined so there shouldn't be a gap.

This is a close up of those lines that were in the previous image. I don't believe that these are what's causing the problem

Alright, apparently my questions in writing were deleted. In the first picture you can clearly see where the lighting got screwed up after I rebuilt it in unreal. The second picture shows what the model looks like in maya before i exported it as one static mesh. I'm concerned with the gaps/lines that are showing up in the maya model (Circled In Red) I'm wondering if those are part of my problem or something I don't need to worry about. In the 3rd picture i'm showing an up close of the lines/gaps that were in the previous image. I don't think those lines/gaps are causing the problem but if they are what is the fix to something like this? If someone could give me a solution I would appreciate it.

Do you have any ideas, what is causing the seams in Maya? Do you get any warnings when importing your model?

I'm not sure what is causing the seams. I don't get any export or import errors when going between the programs. To be honest i'm not even sure why the seams are there. All the walls have been snapped together so realistically there shouldn't be any seams to begin with.

HI EnergyPlaysGames,

The lighting artifacts your getting is expected based on the way your have authored your meshes.

https://wiki.unrealengine.com/LightingTroubleshootingGuide#Shadow_Seams.2FShading_Differences_with_Indirect_Lighting

There is one thing I've not added to the guide for this section right now and that's if you're importing this as a single object or you have multiple planar pieces, like your wall, that make up a single wall in maya and will be a single mesh in UE4 then you need to weld the vertices for the faces otherwise lightmass won't know about the shading on the other edges to help them blend together seamlessly.

If you're reassembling this model using modular pieces in UE4 you're not going to really be able to correct this since these aren't part of the same mesh and will never know what the shading is on the other to blend them properly. This is something we hope to be able to do in the future but haven't gotten around to it just yet.
