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"

Replacing Point Lights with Emissive Materials

Hey, i am new to UE 4 and i would like to use it for achitecture visualisation. Therefor i`am trying to figure out if it is possible to create a emissive material, that i can drag onto bulb meshes that will lit the scene. I am experimenting with a simple scene and nothing compares to a Point light. I can create an emissive material that lights my room. But it doesnt promt shadows with sharp edges. I baked the light and set the resolution to 1024. Also i checked that the material and the mesh should cast shadows. alt text

You gotta ensure that Use Emissive for static lighting is enabled on the mesh in question(light bulb in your case). You need to crank up emissive high enough to see the effect. But be informed, that this type of lighting is not consistent between lightmass settings and is heavily affected by lightmap resolution and quality settings. Overall using point lights to represent a lightbulb is better.
