Hi, it's me, wavef again.
I've made a Real-Perspetive (not shear things) mockup in AD and you can see the demo in the gif below ( ad source file provided ).
it's a unreleased and unstable function in AD, maybe crash your app, damage your un-saved files, blow up your computer~ I don't know.
And you may notice "Mockup-3" in the demo has some render issus and it also bring that problem to the exported bitmap, that's why it's unreleased.
Keep in mind DO NOT copy and paste anything from this file to your working project !!!
