I’ve exported some Icons I made for a client in illustrator and now the SVGs have some black areas. When I export them as JPEG, they look normal.
I made 3 Icons with a lot elements and there is alway one black area in each of them.
It would help if you posted a link to either an image or the actual file. That way, people could better assess the problem.
In general, SVG is a relatively simple format that doesn’t support everything that Illustrator supports. It sort of sounds like a path direction problem, though.
