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"

Light Bleeding In UE4

Hi there I recently have been trying to make some objects and have had some problems with light bleeding on objects.alt text

This shows 2 walls placed together with a light bleed down the centre. I'm not sure what is causing this, I have checked many videos. Here are the things that I have done...

  • The world lightmass settings are 1, 3, 2, 0.6 which I checked in a previous video which apparently helps with bleeding.

  • The Light is a stationary light.

  • The lighting is building at production quality.

  • My custom light map is aligned to the grid in maya with the grid lines every 0.0161 units.

  • The lightmap on the object is at 128 resolution.alt text

Here is my light map in UE4. Anyone have any ideas what may be causing the bleed? Do I have certain units wrong? Or am I setting up lightmaps wrong? I'm fairly new to light maps.

Product Version: UE 4.8

Think I fixed it, increasing the lightmap resolution to 256 solved it.
