I'm creating assets for Unity3D. Reading and searching on Internet, even here in Blender Stack Exchange, i understand that the best way to bake (in order to optimize and have still good quality) is using the Blender Render instead of Cycles Render.
For this reason my question is related to Bias and Distance
I baked a lot but i can't still understand what is the correct meaning of these 2 stats; i search from wiki to sites like this one Baking normal map - distance and bias difference? but i can't focus the point (damn my mind ^^).
What does each of them help to?
I know the Bias from wiki "Bias towards further away from the object (in Blender units)" . . . but this . . . What does it means?
What is their role in order to improve the quality of my bake?
Is the "Distance" similar to a Cage?
Thank you a lot for anyone will help me to understand this thing
