How to make a complete mode track!

I think a lot of people should learn how to make complete mode tracks for many reasons.
One reason is, they think they could make it very hard but you could do way more in complete mode.
That's pretty much it. Anyways, you need a flat image (could be a GIF) with no things coming towards the screen. Also, you don't need to have something like a thwomp, you could just place a thwomp. Don't forget to resize it if it is too overscaled. About checkpoints just go to one of hoppingicon's topics. Another thing is don't forget to right click/double click on spots that are white/dark. You can do the same thing to things like items, which will have an option to make double items. You can also do the same with ramps with jump height. You can make shortcuts to by right clicking on a dot in CPU route. Also, don't just search up an image of the minimap of Sunset Wilds from MK8DX. Please, please don't make a troll track. So, yeah, those are the instructions to making a complete mode track. I might add more to this.

Where do people find these images

They don't find the images, they likely make the images using a website that can be used for digital art
