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"

How do you make rain that actually makes puddles

I want to make this ultra realistic simulation of a rain scene. Where when it rains the rain that fell turns in to water when it touches a certain mesh and when it touches the landscape. So when it falls touches for example and touches the roof of the house it will turn into like a water splash then turn to water. I know how much resources this will use but unjust want to try it out. But I have a concept too. The brain will be some actor and when it touches a mesh or landscape it will play an animation which will be a rain drop splashing then after the animation is done its properties will turn into water. I am not expecting to find answers for this but if you can it would be nice and I have no experience in ue4 c++ and blueprinting what so ever. And animating.
