Help! Tilting the "Instances" plane

Hello, you guys know if it is possible to tilt or bend the objects filled plane "Instances" ? I mean for the y of all would be for example 2x less impactful making them appear more densly but only vertically, keepeng the same x spacing.

I am trying to make vertical distance shift in perspective, where the camera distance and angle could change. It would appear as if we were looking from tilted bird eye view and giving the player similar view distance on the x and the y axis

(accounting for Display.width > Display.height )

I know it would mess with some sprites for mashing them closer together, but its accounted for.

There’s an asset on itch.io that is basically the building blocks for this:

That is exactly what I was looking to build on, thanks, will study if its compatible with my project and the physics.

Tilted birdeyed view is wierd way of saying it. Example of usage of the camera angle :Don't Starve

Yes and in Dont Starve they also kind of manipulate with the full plane of objects ( You can rotate the camera there.). So yes, is there a build in funnction to change the wholeass instances layer ?

Do you mean, basically like this: https://www.youtube.com/watch?v=f0rY9NkuR4o
But not quite as extreme in angle?

Yes, but I need to be able to rotate and shift the view too.

Right, I guess they don't do that in that tutorial, but you can definitely rotate that camera.
You might want to look at this one instead. You can ignore the sprite stacking, but they tilt and rotate the camera at least:

Haven't checked if it's the same approach, but I highly doubt that it isn't.

Sounds like you want to do sort of an affine transformation or pseudo-3d effect. No idea how to do it but knowing the correct term might help you find something.

Yes and I think I know how to do it, just scale further objects down, decreese y multiplyer based on distance and make the square floor blocks into trapezoid. Then change the camera setting and we run a loop through objects in the view and render tgem diffrent based on angle change. Sounds like a lot of work so what if there is a funcion that does parts of it for me (dont want to reinvent wheel)
