I'm happy you figured it out. I haven't worked with Construct since I made this two years ago. :-)
I did have a lot of fun making it though (and the whole game was made with the demo version's limit of 50 event sheet actions, which was an *interesting* challenge).
Use a 2D sprite with animation on the side of the 3D shape. At the bottom of the Properties panel for 3D shapes is "Use object image for faces" which is where you assign the 2D sprite or sprites you want to use. The 2D sprite must be in the same layout as the 3D shape it's applied to so put it outside of the camera's range so it's only seen on the 3D shape.

Love to see more people working in 3D in Construct.
Yes, the projectiles/spells are 3D shapes with only one face visible, else they wouldn't appear at the proper angle. Sprites can only face the floor.
I know VoP has a wall stick issue (but at least one of the very earliest FPSes did too) but I've since found a fairly easy way to get wall sliding working. I don't exactly understand how to implement what you're suggesting, but trying to work through it led me to the solution I'll use in my next game, so thanks!
Thanks.
