Background Matte

Getting Started
1

I’m creating a 2.5d platformer.

The artist I’m working with is creating a 4096 x 2160 (using procreate) background image for
the entire level.

In Unity, the camera will obviously be positioned to only reveal portions of the entire background
image based on how the character moves.

I can add more object’s into the image to play as smaller pieces of the platform such as
floating chunks of land to act as ground, allowing the character to jump onto.

Can I highlight certain aspects of my main 4096 image to act as ‘ground’ and other parts
of the image then won’t be?

Thus, my main question, is it reasonable to design the art in this fashion?

I’ve watched endless tutorials and it seems lots of people use different layout strategies for the artwork but
I’m trying to find which one is a good starting point. This way my hand artist can already begin designing work that I can use down the line as I learn more myself. =)

Yes, you can simply put invisible boxes (or whatever shape you need) with colliders on top of the background image where you want the character to walk.

Also should I create using 2D mode or 3D or can I simply toggle between the two?

The goal is a 2D game but w/ parallaxing backgrounds and maybe some 3D elements.

UPDATE-- nevermind – i started watching the 2D tutorials here on this site and they answered this in the first video lol
