strange problem

hi,
there is a strange problem.
first , place a Cube at x=0 ;y=0; z=1 ( paint the vertex some color )
place a lamp ( any where the same problem)
place the camera x=0 ; y =0; z= 10; and let the camera look at the ( 0:0:0), set the Rotx=0; Roty=0; Roz=90;

then , export all the scene to .sio2 file .
the problem is the simulator is all black after run it ( but the blender rendor is ok ).

if i change the camera Rotx=1 ( or rotx=0.1 ) all is OK in simulator .

Strange indeed, have you update the camera direction (sio2CameraUpdateDir) ?? If not try to do it if you did it maybe send me an example project to show me where the bug is... And have you follow the video tutorials? If not I really suggest you to do so... maybe you are missing a step that I cannot think of at the moment...

Cheers,

yes, I have watched your new youtube video, it is very clear.

but the problem is why if i set the camera locate at 0:0:10 and RotX=0; roty=0 ; rotz=90. the screen is black.

and if I set the same camera locate (0:0:10 ), and Rotx=0; roty=0; and rotz=0.1 (or some other eles) , all is OK.

yes, I have checked about 10 time , all the same problem.

YES, I have set the sio2CameraUpdateDir before SIO2CameraRender , the same problem.

Which tutorial template you are using?

I used the tutorial03 code , and iPhone sdk 2.1 , macos 10.5.4 Macbook Pro .
