Okay, like, i’m a noob, and i rly don’t know how to import an image in XSI, just a 2D image, so i can use that one to make it 3D
Can anyone pls say me how to do that, i rly searched a lot of places....

Just drag the image file to a viewport.

Look up “image clips:creating” in the index.

Creating Sources and Clips

The easiest way to create sources and clips is to drag and drop selected image files from a Softimage browser into the background of a viewport. This is particularly useful for importing a large number of images. On Windows, you can drag and drop from the Windows Explorer or a folder window.

If you want to create sources but not clips, open an explorer, set its scope to Sources/Clips, and drag the images directly onto the Sources node.
