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"

your going to want to create a mask for the emissive. essentially you want a texture where everything is black exept the parts you want to glow those will be white.

the simplest answer would be to UV-unwrap your model and export the uv layout.import the texture into a image editing software and find the sections you want to glow and paint those white and have the rest black.

once you have the mask you will need to import it into unreal and use it to control the emissive in a material.

my horrible quick guide: alt text

There are other more proper ways to accomplish the same thing but those involve baking and would be a little more complex. to learn more about blender in general look up blenderguru on youtube.
