I really like the effects, C4Ds and renders you put into the sig .. However i am more of a fan of a good background with a render and text .. But i really like this!
Does a png file keep the editable layers? Somehow i didn't think i would be editing. What a stupid thought in hindsight.
No, it doesn't. PNG is higher quality bitmap filetype, and it saves transparency. If you want to keep editable layers, you'll have to keep the psd, and then save it separately as a JPG or a PNG.
