I have this problem on an older HTC Desire HD phone which has Adreno 205 GPU. Make sure you don't use texture compression when converting your model to .ive. At least that was the issue for me. The same model displays fine on a Tegra 3 tablet, but on the phone only without texture compression. Different hardware has different capabilities and what we take as granted on desktop is often far from granted on a mobile GPU :( Regards, Jan
