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"

Billboard sprites have hard edges

So I have a Billboard with a Material that looks like this:

Basically three Billboards with materials similar to the one above, working with opacity masks. The problem I am encountering is the following:

The blue background is the material picture on top. The Circle and the icon in the middle are two different billboards, constructed in a similar way. Why does it look so pixely and how can I fix it?

They're pixelated because the contrast on your radial gradient (derived from the Density value) is super high, combined with the shader model being Masked instead of Transparent. You can modulate the edges of your opacity mask using dithering

or you can switch to a translucent shader model and the edges should fade off a bit more smoothly if you lower that density value a bit.

Good luck!
