What this article shares with you is about how to make normal maps in big data. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

Normal map is mostly used in cg animation rendering and game screen production. The model with high detail is baked into normal map through mapping and affixed to the normal map channel of the low-end model, so that it has the rendering effect of normal map, but it can greatly reduce the number of faces and calculation content needed for rendering, so as to optimize animation rendering and game rendering. Today, the editor of the wing fox network will fully explain to the students what is the normal map? How to make normal mapping skills?

What is a normal map?

To put it simply, normal mapping can show almost the same effect as the high-face model on the low-face model. Similar to bump mapping, more realistic normal mapping mainly allows the game low model to have advanced model details that are rendered and baked by 3D software such as 3dmax or maya, and normal maps can also be generated through ps and crazybump.

If you want a more specific and detailed understanding of the normal map production principle, you can watch this set of high-quality course "Advanced Film and Television Portrait of the arrogant Lady of the whole process of making Chinese course" study video, the tutorial will introduce in detail the knowledge points of making normal map, it is not very difficult, it is worth learning.

Second, the skills of making normal mapping.

Many times we are in the production of normal (normal) map, are not fine enough, but also need our own drawing some small widget skills to improve the map, today mainly for you to use our great photoshop to improve our normal mapping tips.

1. First of all, put the turned normal map away. Then create two new layers on top and draw the details you need in pure white on the top layer.

two。 Then fill the lower layer with black and merge it with the upper layer.

3. Then open the filter in turn-- nvtools--normalmapfilter

4. Then open a window. Models made with max generally check wrap and invert y, while models made with maya check the invert x option in the middle. Check 4 sample animate light, as well as the average rgb on the right and the unchanged below, and finally click ok.

5. Then click on the blank space of the conversion layer with a magic wand and remove it. How to set the layer to overlay. Then double-click the layer, open the layer style, and uncheck the box before b (b).

6. If you import it into 3D software and find that the normal is inverted, then directly select the inverse normal layer, select the green channel in the channel, and ctrl+i reverses the normal ok.

The above is how to make normal mapping in big data. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
