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"

Change RenderTarget Alpha to 0 past max view distance

I am using an actor component: rendertarget2D, with a max draw distance of 400.

The sky still draws in the diffuse channel and the alpha is white - the sky is much farther away than 400. Is this a bug or an oversight?

I would imagine that the alpha should be white for stuff in front of the max draw distance and black for stuff past the distance.

I tried setting up a green screen material on mesh behind the actors captured by the rendertarget then using in the material a Blend_Exclude and it works up to a point, but maybe I can do the shader set up better, without losing color from the original texture. I attached an image in case anyone is interested in green screen.

Hey, did you find out how to exclude the sky without the color keying?
