Hi, Basically I am a programmer. I am not sure whether this question is valid for this forum or not. 1. I downloaded a free fbx house model. 2. Import it into Clara.io and attached textures, lights and camera. 3. Export it into .babylon. After render it into babylon it showing some black gradient marks. Can anybody tell me why this is coming and what should I do to resolve this problem. I have attached an image for reference. Also please let me know, necessary steps all modelers should take care. Thanks Somnath
