I would like to have simple geometry buttons in my application, like play, stop, record buttons on videocamera.

Unfortunately, I don't know how to prepare good asset for them.

If choose `Image Asset` to place differen resolutions in differen folder, I am confused by `Asset Studio` available options:

Here is a strange list of icon types, but no one says "button" icons.

Also, I am not sure, what size to choose for mid-resolution in pixels.

Next, if I choose `Vector Asset` I face with limited support of `SVG` in this program. At least, it doesn't understand SVGs created with Adobe Illustrator.

So, what is the best choice?

**UPDATE**

I drew blue shape in Adobe Illustrator and expoted it to SVG. The result is following:

I.e. color is lost and error message 

```

displayed.
