2.5D Oblique Projection v1.1
Oldschool isometric camera:
– Create the retro look of old isometric games, but now in 3d!
– Perfect for simulation games and sidescrollers!
– Also great for technical illustrations and minimaps!
– Works 95% like an orthographic camera (see caveats), so movement, rotation, shaders, shadows, gizmos, etc. work as you’re used to, at the performance you’re used to!
– Try a demonstration
– Watch a game that uses an early version
More to come..
Caveats:
– The camera has the same restrictions and features as Unity’s orthographic camera (e.g. deferred rendering is not supported).
– The Unity mouse system (OnMouseDown, etc.) is not supported. You can use raycasting, of course. Example included.
– Occlusion Culling has not been tested.
Models used in the demonstration and screenshots are freely available on the asset store. Thanks Nobiax & Unity!
