Hi guys, thank you for coming. I have encountered 2 problems when baking the normal map from high poly to low poly. I would be appreciated if there is any help.
I have 2 mesh, 1 is the low poly, and the other one is the clone of that mesh with a subdivide modifier up to level 3 (I call it high poly).
From P1 in the picture, there is a octagonal cylinder with a circle cylinder “shadow” baked from high poly on my octagonal cylinder. But what I want to is a circle cylinder (or near circle) without corners after the normal map has applied. I have followed Blender Guru’s Anvil tutorial but I don’t feel like I have missed something.
For P2, my normal map appears some red and green area. From what I’ve learnt from blender guru, it is not a good normal map. I tried changing the ray distance setting, but no matter how I set there are red and green.
Thank you so much if you can shed some light for me or other new users who might face the same problems.
