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"

Important Lightmass Settings missing from Foliage Tool!

So there are a number of important Lightmass settings missing from the Foliage Tool's Static mesh instance settings - most notably:

  • Use Vertex Normal for Hemisphere Gather (This one is super important as a lot of foliage uses bent vertex normals to look volumetric)

  • Use Emissive for Static Lighting

  • Use Two Sided Lighting

  • Shadow Indirect Only

  • Diffuse Boost and Fully Occluded Samples Fraction on instances also

My question is why aren't these options available for foliage instances in the Foliage Tool? Right now this is causing me a huge headache when trying to get painted foliage to look correct with static lighting and I cannot consider placing thousands of foliage meshes manually.

Is this an oversight or intentional? alt text

So after a little more digging someone suggested that you can create a new BP which inherits from FoliageInstancedStaticmesh by clicking the + next to the Component Class in the Foliage tool, and then you can edit the initial values of your class:

alt text Unfortunately the Lightmass settings are greyed out! I have been racking my brains and trying to find help on how to fix this but have had no luck so far. I also found an interesting node in the event graph called Break LightmassPrimitiveSettings but cannot find a way to execute it. I feel like im getting closer but have found yet another roadblock.

Can anyone help?

Ok so I ended up figuring this out for myself after much pain and some help from friends - basically, the reason the Lightmass options are greyed out in the initial class values is because the mobility of the instance in the BP is set to movable by default, making the lightmass settings mute. To fix, simply scroll up the the Transform section and select "Static" from the three listed options: alt text

Now you can select whichever Lightmass settings you need!

Hope this saves someone some time in the future!
