How were art assets created in the late 16-bit/early 32-bit era?

How were 2d and 3d art assets typically created in the early-to-mid 1990's (16-bit and 32-bit eras?)

Answer

For 2D, Deluxe Paint was pretty popular in those days.

For 3D, 3D Studio was around on the PC (eventually becomming Autodesk 3D Studio Max later in it's life). On the Amiga you had Lightwave (which was also used for TV and film).
