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"

use TAA, it makes everything a bit blurry but that should "fix" it. Or just use MSAA8X

the english was bad so it didn't come up to me that you meant that those solutions didn't work.

Have you tried setting MSAA to 8x yet?

yeapp, unfortunately it's not work too

try making the object wider. It maybe that the face between the emission face and the outside "shell" of the mesh, maybe too narrow causing this "flickering".

This also happens when you are looking at an object from very far away, because it doesn't know what edge to draw first and the edges become too small.

I maybe wrong though.

I tried it too, I make instead lamp - box with only emissive bottom part - not work

Bumped this, solution not found yet(

update: msaa count 16 resets to 1. On the 8 - far distance objects looks bad than TAA , but close ones good

The neons are too bright and too thin. Its a very difficult case to handle for the AA, and the bloom only make it worse. But anyway it doesnt look like the aa its working at all. Its a standard opaque material?

Have you tried to fake the bloom with billboards?
