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"

Temporal AA Blurs Animating Textures.

So I've made a top-down game where toy tanks can tread about and fire. As the tanks move, I offset their tread texture based on their speed. This works well, except for the fact that temporal AA is blending the texture while it moves, so rather than the treads looking like they're treading, it becomes a blurred mess. The bullets that the tank fires also blur into the floor and become near invisible! I've tried changing the AA method to FXAA, and while it did fix both issues, the aliasing became so terrible, that I don't want this to be my solution. Same goes for MSAA.

FXAA: alt text

TAA: alt text

So my question is this: Is there any way I can use TAA without it blurring specific moving textures or objects? (or just tone down the blurriness in general) Or alternatively, is there any way to use FXAA, but still blur the edges of background objects so that they don't look terrible as the camera pans? Thanks.

I am also very interested in solving this problem. Hopefully somebody can offer some good advice.
