I have not found a good tutorial on what to do with your models to normal map them etc. I know I can use xNormal and make my textures into normal maps but what do I do with my model? Do i just apply the normal map and it works? If someone can please make a tutorial or tell me what do I would love this. Thank you.
You can use any texture as a normal map just by clicking on the ‘nor’ button in materials, which tells blender to read the gray scale value of that texture as the rendered normal, but if you want to make a normal map in a controlled fashion, you should paint it using texture paint. To do that you have to know UV mapping, and unwrapping. Once you have painted your normals map, you apply it by loading the image you painted into a texture channel, and in materials, set ‘map input’ to UV, and ‘map to’ to ‘nor’. So, a good place to start, would be UV mapping, and texture painting. There is another way to make a UV normals map, by ‘texture baking’ which involves making a high poly version of your model, with surface details, and ‘baking’ the normals from that, onto the UV coordinates of the low poly version.
How far have you looked into normal mapping tutorials?
