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"

Lightmap flickering to Low Resolution

Hi guys,

I'm having a problem with my lightmaps.

They seem to be flickering back and forth to low resolution as I move around in the editor or ingame. As you can see in the image, the above one is how it is suppose to look, but it switches back and forth between low quality as you can see in the lower part of the image. It also happens to my materials, but mostly my lightmaps.

Things I have tried: -Delete the Saved and Intermediate folders in the project and restarted -Set Engine scalability settings to Epic -Turn Monitor editor performance on/off

Thanks in Advance

Hi Sandermer,

There are a couple of things to check, but I'll need the following information regarding your scene setup:

  • For the walls and geometry that is getting lower quality textures/lightmap, is this a single piece of geometry (walls, ceiling, floor) or broken up into smaller modular pieces? Give details on how this geometry is broken up if it is.

  • Can you post a screenshot of the more troublesome lightmap popping geometry UVs. (In the Static Mesh Editor in the main toolbar select the UV button and set it to UV Channel 1 in the drop down for the lightmap UV view)

  • What is the lightmap resolution for your mesh(es)?

Let me know.

Tim
