Weird graphic behavior in pixelart platformer

CProrammer

Just look at that: https://youtube.com/watch?v=6DfKBHQnaRE

I dont know how to explain what is going on with this graphic but is there any solution to remove that?

CProrammer

Pixel snap is on, filtering on, camera process mode set to physic, vsync on

Do you mean the scanline kinda thing that went through the full screen?

yes

@CProrammer said: filtering on

Have you tried filtering off?

CProrammer

Yes, it doesnt help also

I moved tilemap to another project and there is the same problem: https://youtube.com/watch?v=k_nOMcGazQ0

Hmm looks like a moiré pattern. Is there perhaps any scaling going on?

CProrammer

No, I don't scale anything. I make research all the time and for now I have a clue with NVIDIA graphic cards and GODOT problems, there is also a special option in settings "Use NVIDIA Rect Flicker Workaround" but it doesn't help also, on the internet there is no any answer that help to solve that. It's kinda insane that this kind of problems appear in game engine.

I use Stretch Mode : viewport Aspect: Ignore so this is kinda scaling but problem also appears when I set 2D/Keep

TwistedTwigleg

Hmm, with the stretch mode set to Viewport helping minimize the issue while 2D/Keep doesn't, it sounds like it could be a scaling issue. Is the brick background or tiles scaled in your game? If the node's scale multiplied by the image pixel count doesn't equal a whole number, then you will get sub-pixels that will appear and disappear as Godot tries to guess which pixel it needs to show given the non-whole number pixel. (I probably described it poorly :sweat_smile: ) I believe a scaled/zoomed Camera2D can also cause the sub-pixel issue, so if you have a scaled/zoomed Camera2D node, you may want to see if adjusting it's zoom value helps.

CProrammer

There is no a single scale in project.

CProrammer

So I get a clue that "aliasing between the viewport size (lower resolution rendered surface), and stretching it to fit on a fractionally scaled window." So I still have no idea how to setup my project with 16x16 tileset to fit all screen resolutions. I made a simple recreation project if someone want to take a look: https://ucarecdn.com/e5495738-1f12-4bca-bd92-c91f83aa29bc/
