Which reason to change the default value of FixedDeltaTime ?

I see someone change its value of the refresh rate for physics update in Unity editor during a Game Jam. I don't ask him the question but why and when you need to change it ? On which needs you increased or decreased its value ?

I’ve added the ability to rotate the camera around the car - it completely changes the way the game Lost Host feels. But I think this is exactly what the game was missing :)

Unity 2d izometric game tile stay in the background

I'm trying to make a game using tile map in unity, but I can't solve the problem that the tiles that should be on top stay in the background.

"Window" shader

I want to make a 2D effect where the texture on an object looks like a window into a larger texture. As the camera or object moves, the visible part of the texture shifts, revealing different areas of the bigger image behind, rather than the texture being stuck to the object itself or scrolling UVs. A rough example of this kind of effect is the Galaxy Skin in Fortnite, but I’m aiming for a 2D version of that 'looking into another space' feel. What would be the best way to approach this?

Two years ago I quit my full-time job to build my dream game — Universe Architect — for all you space, physics, and quantum mechanics freaks. How do you like the latest screenshot? The game goes live soon — do you think it was worth it?
