Can anyone help / advice?
All the particles are visible while the camera is moving or rotating, but when the camera is still the distant particles disappear
Here is a video to demonstrate:
When you turn sideways it’s difficult to say whats causing them ALL to disappear. However the stuff in the distance is the temporal AA, I would try turning it off and see what you get. 1 pixel white dots on black are probably a worst case scenario for this type of AA.
I can’t recall what exactly root of this problem, but I remember there was a solution in 4th or 5th video
Thanks, disabling AA does make all the stars visible - is there a way to apply this *only *to the particles / star material
…Or is there a better way to approach this? (because it doesn’t look anywhere near as good with no anti-aliasing :()
Why not make the stars bigger? A 9x9 pixel star or thereabouts will blur with the AA into something about 1 pixel in size (with the rest being gradient), at least one would expect.
3x larger makes all the stars visible, but it looks terrible… they look too big (even in the distance).
The other problem is if I make them any bigger the AA no longer fades them at all
Here is a picture to show exactly why scaling them up doesn’t look good (they are supposed to look very distant!)
So the stars need to be scaled down as they get closer… but then
the most distant stars don’t look very far away, and look too similar as the closer stars…
In other words, the “depth” of the starfield is lost…
I will keep trying alternatives… possibly I need the particles to spawn closer (they become visible properly around 400,000 units away) and decrease the radius of their spawn. I’m going to face problems with how close they are to the player though - they are technically supposed to be very distant stars, so when the player moves around if they’re physically too close to the playable area it will not look convincing at all!!
The trick to avoiding this is in the material for the particles. There’s a checkbox in the material properties called “Enable Responsive AA”
This will force the particles to ignore the Temporal AA, but can make them appear more flickery. It will also disable the AA of anything rendered behind the particles, so don’t use it for big particles or particles that can cover a large portion of the screen.
Edit: My bad, not the right solution.
Hey sneh -
The TXAA is your primary problem ( 's solution should solve the issue OR disabling AA) but you may want to also check to make sure that the bounds have been set large enough. Any time you camera rotates out of those bounds the particles will disappear.
