Preface
When we use UE4 and UE5 to create materials, we often encounter the use of normal maps. To use a depth map to generate a normal map, you generally use software such as PhotoShop. For a PS novice like me, using PS is a big headache. Even if it is barely made, it is time-consuming and labor-intensive, let alone making a large number of normal maps. Let me introduce to my friends two tools for making normal maps:
1. crazybump
2.Normal Map Generator
1. What is crazybump?
1. Overview
CrazyBump is a small tool for converting images into normal maps, which is very easy to operate. There are not many adjustable parameters, and the effect is richer in detail than the PS plug-in. It can also export normals, displacements, highlights and fully enclosed ambient light maps at the same time, and has an instant browsing window. It uses ordinary 2D images to create normal images with Z-axis (height) information, which can be used in other 3D software to make a low-precision model have high-precision effects. Used extensively in games.
