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"

[Feature Request] Directional Light Variable Penumbra Shadows

This is a huge feature I've been wanting ever since I needed it with UE3. The sun rarely produces sharp shadows in real life, yet I can never get a directional light to cast variable penumbral shadows, where the shadow gets increasingly softer further from the shadow casting object. I know you can do this with point lights by setting the light source radius (though it doesn't seem affecting the shadows in Rocket. It worked as expected in UE3). Is there a technical reason why this is not supported with stationary directional lights?

Example:

Edit: Just to be clear, I'm talking about baked shadows, not realtime. Though realtime would be awesome! :)

Hello James,

I reviewed your request and entered it into our database. I found a similar command "Shadow Filter Sharpen" that will manipulate the penumbra, but it is not based on distance from the light source. Thank you for your request!
