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"

Baked static lighting loses color under Lit mode


i've got several static lights in the scene with varying hues, but when i bake static my static light, i seem to lose all that color information from the lights and get a greyscale result in Lit mode except for the emissive .Detail lighting still shows the correct color information on the other hand. I assumed it was either the post process or world settings but i have environment intensity set to black and 0 and I don't have saturation checked in my my post-process.

I've also checked my material but it's a very basic setup and I couldn't find anything to suggest a fix. If anyone has any ideas or suggestion would be helpful.

Detail lighting is not always the best for figuring out how your lighting looks, can you snag a screenshot of the "Lighting Only" mode. Note this is different than detail lighting.

Docs always say detail lighting and lighting only are similar minus normal maps but I often see a huge difference in them and detail lighting is often inaccurate. Especially with baked transparent items.

I have a similiar issue. When I PIE and in the Editor view itself my baked point light has a white color, however when I look at my scene in "Lighting Only" mode then the color of my light is blue as it should be. What's the problem? I have UE4 4.19.

best regards

If I am not mistaken I think this is a current limitation of PBR rendering.

If you bake a static light on fully metallic surfaces, the surface won't receive all of the lighting information such as the color. However if you have a stationary light then it is possible that metallic surfaces show you the proper color of your light source.

Here is a link to a similar question:

static lights lose colored specular on metallic materials
