I know he's put a lot of work into it but i would have to advice anyone against buying this plugin at the moment.
Support is non existent, i've asked questions that never get a response.
There is no documentation.
The few examples that come with it use deprecated commands.
Yes it requires some understanding of 3d, which i have, but its still all just painstaking trial and error of each command, of which there are many.
Last I heard QuaziGNRLnose was upset with the limitations for Plugins in Construct 2. Interaction with Q3D is cumbersome because of this. Maybe he's (she's?) waiting for Construct 3 for a overhaul.
And I REALLY hope that's the case, cause I'm learning to love this plugin, even with all limitations it has. I tried looking up what it would take to make a 2.5 D game in Unity and, God, what a pain. There's really nothing like C2 event system out there. I'd rather have limited 3D graphics in C2 instead of a powerful 3D engine I can't handle.
