See the code below (its the Heli demo from the Samples) and unremark 'X_DRAWOBJ 1, 0' to crash... GDB console output below that. "Program received signal:  ââ,¬Å"EXC_BAD_ACCESSââ,¬Â."

Also, what is "backing: 320 x 480" from the GDB? I set this program to landscape(480x320)?

Use rgb hex for the texture coord colour!
Try changing RGB(255,255,255) to RGB(0xFF,0xFF,0xFF).

Ive tried it in a few programs,  'X_DRAWOBJ' is causing problems.
Cheers,

X_DRAW causes the problem?
I think it's because of X_OBJSTART and such. Try saving the object and load that file on the iPhone. My tests with loaded objects are all positive.
However... the S-Zero uses X_OBJSTART, too and that one worked for me :/

Oh dear.

Yes, I can load and display .DDD but not create new 3D object within the code.

Still at least I can get some 3D up and running.

Anything news on this one Gernot, its stopped my project dead.

Anything on an ETA for this fix yet Gernot?

I have a guy waiting for this program to get finished and I am trying to keep him updated.

I can't tell. What I can tell is that it won't be before wednesday, as I have to give a training for 10 engineers in my work on that day. And I'm a tiny bit behind schedule with that <shiver in fear smiley>
So so sorry.

No problem Gernot, I understand, I'll pass on the info.

This will work if all of the vertex colours are set to RGB(0xff,0xff,0xff) only. So if you want to demo with colours on the iPhone, apply a texture map with the appropriate colours!

Excellent debugging!!!!!
If it's the colours that make the problem, it's much easier for me to debug now.
-> Always use a texture for the colours, that's much, much faster!
In my Dr. Shiver game, the objects are unicolor, but I have an 8x8 texture with the colour "palatte"

While this seems to help with the first X_DRAWOBJ ("//      X_DRAWOBJ 1, 0"), you soon run into the trouble when you try and draw an object within the second PUSHMATRIX ("X_DRAWOBJ 0, 0") this cause the same old error. Only when a PUSHMATRIX is nested within another PUSHMATRIX AND you the try an X_DRAWOBJ does this seem to happen though.

Call dump, #0 is the actual crashing OpenGLES call...
