I have included light setup in the scene file. This has been modeled with good production standards. This model was constructed with utmost care and attention to detail, with clean edge flow for good lighting n shading.
For Orange Pulp surface I 've used SSS shader ,rest all geometry I 've applied Maya n Mental-ray shaders with the colors shown in the renders.I 've tried to do the best work to go close to the realistic look n feel.Hope u like it.
Only Maya format contains the shaders and lit setup used for rendering.other formats provides only model geometry.
