Hello,
I have done a few 2D games, Cocos etc, but for a new app, I want a 3D world enviromnment, that the user can walk around. It is not a big world. It is just 1 room, or maybe 2 max. The user should just be able to walk around and touch things. No shooting, aliens, etc. Can someone recommend a simple 3D room engine for such an app? I just need a light weight 3D room engine. Also if anyone could give me a pointer as to what software you use to create the room? I need wallpaper, floorboards, furniture, windows etc.
Thanks

You can try SIO2, you can model all the 3d stuff in blender, and then export to the sio2 engine and load your scene on the iphone

Unity is pretty nice too but pricey.

Too pricey? It's FREE!

For the iphone version it's not cheap, for the non-gimped iPhone version it's a rather lot of money.
