Ok I tried what you said;
obj3DMain3 = Primitives.getSphere(20, fScale);
obj3DMain3.calcTextureWrapSpherical();
obj3DMain3.translate(20, 0, 440);
obj3DMain3.setSpecularLighting(true);
offsetShaders.Set(obj3DMain3, R.drawable.venus_bmp, R.drawable.venus_normal, R.drawable.venus_height, 2);
obj3DMain3.calcTangentVectors();
obj3DMain3.build();
obj3DMain3.strip();
world.addObject(obj3DMain3);
..plus I added 0.3 to the Ambient vectors in the shader which has improved the brightness, but that lightning symbol is still appearing.
GalaxyNote: Extremely dark output on first launch, you can only see the lightning effect. Jump to another app and back, it looks like the image in the attachment.
Tegra3 device: Shader looks fine but again the lightning effect is evident as seen in the attachment.
Why is Thor cursing me with a bolt of lightning?
