I’m in the process of transferring my app to Unity 3 (Pre-view). I really like the look of it so far. I’ll let you guys know how easy or hard it is to transfer from 1.7

Thanx man. I’m anxiously awaiting my turn at U3.
Got mine this morning.
The only real problem I’ve had was with a directional light. Other than menus my current project only has my testbed scene. When I first opened it I noticed it was really dark. I fumbled and fiddled with ambient light and all the materials to no avail. Then I started mucking with the light in the scene and realized that it wasn’t “shining” and no matter what settings I changed there was no effect. I deleted and re-added it and all is now well. Weird.
Built and ran the project fine first try. I had to do the settings for the icon again, but no biggie.
The only thing I’m not digging is the UI color. Too dark for my taste, at least right off the bat. It may grow on me. And it may be customizable, I dunno.
But all in all the few hours I’ve spent with U3 have got me in a happy place.
You can change it back in the prefs.

Yep, just found it. Unity Preferences/General/Use Pro Skin.
LOL, now I think I like the dark better. :roll:
The race car tutorial doesn’t seem to work very well. The physics are all off. when you go to turn the car it just keeps going straight. Also, when it hits an object and starts to spin, it should stop spinning after a sec or 2, it continues to spin.
Is there any performance increase?
yeah I’ve noticed something borked with the physics also…
I have a nicely tuned rally racing physics working in 2.6.1, but after going to 3.0 beta, everything is moving in super slow motion, like all surfaces have virtually no friction…
car wont accelerate or turn…
and turning up the grip just makes the car flip over at super slow speeds.
Everything in the scripts seems to be running just fine… but its like the physics are just all different for the wheel colliders… I hope this isnt the case.
Hopefully I’ll find something else wrong.
anyone else experienced any physics related issues ?
joining group of physics behaving differently spotters…
it seems like it is more sensitive, resulting in smoother movement of rigidbodies
in my case I had two hinge joints simulating car dampers ( viewed from side ); in beta one ‘damper round’ until car stabilizes after hitting a terrain obstacleness
takes longer time and thus appears to be slower and less responsive
I haven’t played with physics settings though, hopefully it will be ‘just’ a matter of proper parameters setting
I submitted a bug report, but I suggest you guys do the same, you may have more info on it then I provided.
this can be installed along side unity2, right?
I’ve got Unity 3 beta and Unity iPhone 1.7.1 co-installed on my Mac. Installing Unity 3 beta overwrote my Unity 2.6.1 install on my PC. I didn’t have 2.6.1 installed on my Mac.
Oh, vertex snapping… YAY!
you can have it in parallel yeah. on windows just choose a different directory.
on osx, rename the unity directory and the name of the application
Is there normal mapping in unity3 for iphone/ipad/ ?
if you write shaders that do it efficiently.
there is an ARM7 - OpenGL ES 2.0 target you can use, yeah.
But I would not really recommend to use cg for that nor would I use the surface shader system. You can write GLSL directly so you can opt it for the very restricted mobile platform.
Thanks Marc.
I was hoping there will be one prebuilt for unity3
I’m pretty new at coding so that would have been a time saver for me. I know resources are pretty limited but I’d like to use it sparingly on some artwork just to enhance them a bit for ipad.
Potentially there are some, I might have missed it.
I’ve to say that I avoided the ARMV7 target so far, I’m using ARMV6 and OpenGL ES 1.1 primarily right now cause I have nothing where I gain anything from OGL ES 2.0, I can only use something 
yeah but be careful, as unity always automatically loads the last project, so when you run 3.0 beta, it will start converting your previously loaded project.
So backup your old project…
and suggest you rename your project folder everytime you finishe editing anything, so unity fails to open it on your next launch of unity. then you can choose which project you want to load.
Or hold option when you launch Unity to open the project select window. 
thanks, but there is no option button on PC
tried ctrl, win, alt or shift, but appear not to work. Is there a windows equivalent?
