Still trying to find out how to import or create new textures for CorelDRAW
Do you mean the parametric textures like below? I don't think they have new ones for a while..
As for full color pattern fills, it's fun to make those - here's one I'd made just now.
ammo.zip
it allowed me to make this: (I added some Photo-PAINT effects, then layered 2 more times with drop shadows.)
