Bump maps are less advanced than normal maps because they can only show the height values of a texture, whereas normal maps can show angle as well-which allows them to show detail more realistically. Normal mapping works by replacing the interpolated surface normal by the one evaluated from an RGB texture, where each channel (Red, Green, Blue) corresponds to the X, Y and Z coordinates of the surface normal. From there RGB values are used to produce cracks, bumps, or pores in your model. It is mostly used on objects that need high level detail Examples of software that use a non-PBR workflow are Maya and 3ds Max(without V-Ray), along with Modo. Bump maps are great at adding a lot of low-relief detail on low-polygon objects, so a one-polygon wall could show hundreds of bricks thanks to bump mapping. The rgb information in the normal maps correspond to the x,y,z axis. It’s a bit tricky and it would be quite a pain, to wire everything together, everytime you want to use a normal map. Alternatively use Alt + N to access the Normals context menu then What to Know. Click the folder icon next to the normal map name field.

Tire Cover This tutorial shows how to model difficult rotating objects.
To reverse face normals Select the faces you want to reverse: Select Mesh Display > Reverse > in the Modeling menu set.
PxrSurface can also be applied to objects in the scene by selecting them from the RenderMan Menu itself under the Materials heading.
