the_Shit_hawk The copy/paste difference I mentioned is in the image editor. You can copy/paste sprites into Photoshop in C2.
Thanks for the advice, I didn't know you can save the sprites from C3 image editor then edit with an external image editor then export it then import it to the C3
I really recommend you to use copy/paste sprite and external editor features in C3 Desktop when it's done.
BTW I love C3 and I'm waiting for the new runtime + desktop version to use it.
