Oops, I've been lurking a bit, but I'm very interested, so guess I should finally say something, lol. It looks very well-featured and I'd love to use it for a game in the future, but I'm currently making a 3D game in GMS2 which could not make use of this, mainly due to my unorthodox needs in animation and some rules with my graphical style. I think that the more 3D assets that get out there, the more we'll see an interest in making 3D games with GameMaker. Especially with something like this, if it is as fully-featured as it seems to be. I do feel like some people might have missed this topic, or perhaps they saw the first post and only skimmed over the text and saw the one screenshot which may not look impressive at first glance. Perhaps you could edit the first post and use bullet lists for features, showing screenshots in spoilers which demonstrate the various shaders, editors, animation, etc.? I look forward to your work on this. It's looking and sounding pretty fantastic.
