@Cherry-sama That was actually the entire purpose of that clause in the terms of use.
@Sharm Yeah, but, in my defense, if we look at the Terms section...
Edit does not include upscaling the Ace icons for the use in MV. You can use them there, but do not resize them with filters or anything like that.
When I read "filter", I thought "colour filter" or slapping a weird texture on top of the icons--something that changes the visual look of the icon in a significant way. And, as it says right now, upscaling the Ace icons to MV
is allowed.
I'll give you an example of what the resize looks like, using one of the icons from the Ace RTP.

Honestly, I think that second resize method better preserves the graphical fidelity of the icon a lot better than the first resize. Isn't that the whole reason Avery forbade the use of "filters" to begin with? To preserve her work as best as possible?
(If you want more examples, then I resized the entire
VX Ace RTP Tilesets using this method.)
Look, if this still counts as a violation of the terms of use, then I can find icons elsewhere. But, at the very least, could the Terms section be updated to specify what exactly Avery means by "filters"? Because, right now, it's super vague, and when I asked her about specifics before in a PM, I never got a response. :/
