This recipe will show you how to create a normal map from your scene using the normal map viewport filter. This technique can be very useful in creating a large variety of textures with multiple map outputs. Not only will this recipe teach you how to get a normal map, based on your viewport, but it will also show you how to use that in combination with other viewport renders.
First thing you need to do is import some rocks that you would like to make a normal map out of. If you do not have rocks of your own, than you can open up the file named Rock_Layout.mud
, in the code files for this book.
This was created by duplicating and arranging the rock that we used in the earlier recipes of this chapter.
