Anyone have any thoughts on GIMP for animation?I'm not an animator, but I work a lot with GIMP. Just like Photoshop it is a workhorse for everything related to graphics.
The layer system offers layers, sets and subsets, wich helps organizing the animations. You can do onion skinning manually by setting the transparancies of the layers. There's an animation player that plays layers as animation, complete with definable fps and playing speed.
What you don't get is a timeline. But for sprite animations to be used in Construct you'll barely need it.
I think it is an alternative if you can't afford a professional animation suite. You get almost the same functionality, it is more or less the comfort that is missing. Without this comfort it takes a little bit more time to get the same results.
