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"

IES profile not working

I've migrated a project from 4.15 to 4.16 and my IES profiles don't seem to be working. They just get really blown out. Is this a 4.16 bug or something i'm doing wrong?

Product Version: UE 4.16

Hi,

I have the exact same problem with the IES Light Profiles with Forward Rendering in 4.16. They actually don't work. Are they supposed to work with Forward Rendering?

Cheers and any help will be appreciated

Hi, Guys. I'm also having the same trouble with .ies files. They basically change my point light into a generic spot light, but when I put the .ies files of IESViewer or Relux (light simulation program) they display a different profile than on Unreal. It would appear as though the detail is severely hampered which is probably caused by some sort of setting. Please help.

So looking into it some more, it looks like forward rendering was the issue. If I turn it off i get the correct ies effect. So i'll have to forgo ies profiled lights in favor of forward rendering (it's a VR game). Thanks :)

Hello paynter3D

Did you try to rebuild your lighting? Did you check your post process effects, or are you using right camera..? If you send us a screenshot we can take a look to solve your problem.

Also tone mapper in 4.16 is changed maybe related with this thread https://answers.unrealengine.com/questions/607909/emissive-color-changed-in-416.html.

Thanks.
