How to create a map projection for CC Sphere Mapping
I’ve got a vector graphic I need to distort so that once I wrap it via CC Sphere plugin, it won’t appear distorted–probably using the equirectangular projection (https://en.wikipedia.org/wiki/Equirectangular_projection). Anyone have ideas? I’ve found similar questions on the forum but many link away to a raster image tutorial which would simply not work–I need crisp vectors for the lines.

CC Sphere will not continuously rasterize vector lines. It will need to be a high resolution rasterized graphic.

Fair enough, I’ll have to make it raster. The issue with creating a projection still stands, though.

You mentioned that you had already found some tutorials and, since you’ll be using a raster image after all, I figured you were already set. What tutorials have you found and what about them isn’t working for you?

Ah, sorry. The tutorial that Cow forumgoers have linked is https://www.maxoncomputer.com/tutorial_detail.asp?tutorialID=54
But that won’t fly for line art.

Unfortunately those don’t really help. This isn’t a map.
Here’s the base design:

It’s obviously fine around the center, but towards the edges it becomes warped. Any attempt to manually distort it by trial-and-error seems exercise in futility (tried lens distortions, mesh warps, etc.)

You could take a look at our CFX Sphere Utilities, especially Mappit although it might be difficult if your art covers a large portion of the sphere. Perhaps adding the elements one by one would work. Anyhow, take a look.

Let’s try a different approach:
In Photoshop make square image of desired map.
ThenFilter>Distort>Spherize -100% (minus)
and save new map.
In AE make comp with double horizontal size of your map (height stays same), import your map on timeline, double its horizontal size too,then apply
Effect>Distort>Polar Coordinates – Polar to Rect 100%
Adjust vertical position and vertical scale as desired and add a solid beneath to fill the gap. Precompose. Use this composition as a map for CC Sphere. Rotate on x axis 90 and that’s it.

Tried that as well, as at least as far as I can tell it wasn’t suitable for something you were trying to wrap around the sphere–it just tried to make the design “orbit” it instead.

I don’t get what do you mean. In attached projedt it WAS mapped on a sphere (on the HALF of sphere (hemisphere?)).
Isn’t that what you want to achieve?
Have you tried attached project?
