Just wanted to say I have a manga/comic contest with Clip Studio Paint Ex as prize.
I'm a clip studio paint ex user and can definitely say that this software is well worth it in production. You can get a lot done from comics to paintings and 3D image editing. You can model 3D objects in blender, then texture them and save the obj and textures in a .zip file then simply drag and drop onto the canvas and clip studio will load your 3D model.
Thanks for the heads up on the sale!
