iOS:Overlays not shown on iPod

[igorvlassov]

Hello,
I have following issue:
I see overlays in emulator but don't see them on iPod (3-d gen, 8gb, iOS 4.2.1.)
Console shows overlay & textures are loaded.
Any ideas?
Thanks,
Igor

Need more info. Like how to reproduce it, relevant material or overlay info, which render system, etc.

It's easy to reproduce. I installed recent SDK & use template. If template is running on iPod, right bottom "Ogre" text is not shown. Seems there are common problems with gen2 devices. Yes, apple call iPad 8 Gb 3-d gen, but it's actually a 2-d gen device.
Other problems with template sample are: Ogre head blinking (already mentioned on some threads there), left bottom debug overlay blinking too & stats aren't updated.
About render system: Is there a choice? I created my app using template & didn't touch render system.
I have iOS4.2.1 installed. It's the last iOS version available for that system.

Does your iPod have a PowerVR MBX or SGX GPU? I'm guessing MBX based upon the symptoms.

How can I find what GPU I have? I found model code MC086LL. On forums including on developer.apple.com people wrote 8Gb is not actually 3gen, they don't support OpenGL2.0

That's correct. The item was probably mislabeled on some website. There was no 8 GB 3rd gen model. I just found my 2nd gen iPod touch so I'll look into fixing this tonight. If you want to though you could follow the solutions in those other threads but it requires you to rebuild Ogre from source.

[igorvlassov]

OK, I'll try to check them.

After I recompiled Ogre from source, I found I didn't need to do it at all. I must only change FSAA parameter in ogre.cfg to FSAA=2
