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"

Lightmass Ambient Occlusion In Forward Renderer?

I'm having problems getting Static LightMass-Baked AO in my game using the Forward Renderer. Is this by design while using the Forward Renderer? I've enabled all appropriate settings relating to AO.

Product Version: UE 4.21

I believe it says in the docs for the forward renderer that AO is not yet supported (seems true as of 4.19 which I'm on currently). Which leads me to the question about how people's workflows looks... If you need AO to be baked into textures, but it isn't supported in forward rendering, how do you easily switch between forward and deferred to get the AO bakes to happen?

Do you have to set up 2 different projects? You can't quickly switch in single project because the shaders all rebuild, which slows down the workflow tremendously.

i'd be interested in seeing the documentation explaining why static, lightmap-based baked AO isn't supported in forward renderer. I can't find any docs about static ao not being supported
