Ray-MMD is a real-time render effects library for MikuMikuDance. Ray-MMD is specifically designed physics-based and high degrees of freedom, so as many parameters as possible are added to fine-tune the effects. This document assumes that you already know some of the basics of MikuMikuDance and MikuMikuEffect. In this document, MMD is short for MikuMikuDance and MME is short for MikuMikuEffect.

Ray-MMD is only tested with mikumiudance 926 and above (64-bit versions), so if your version of MikuMikuDance does not meet the requirements. We recommend you download a new version of MikuMikuDance.

Ray-MMD is not an off-the-shelf effects library and you may need to make some adjustments to the parameters when using it. The knowledge of the framework implementation itself can help you solve many problems. Warm tones may require fine adjustment of the color temperature. Bloom is disabled by default. You will find that Ray-MMD is not a single effect, it is more of a set of tools. Understanding the meaning of each parameter can help you to achieve the results you want more quickly. If you want more freedom settings in your rendering and dig deeper to understand PBR, this rendering library will be more suitable for you.

Ray-MMD is not complicated, at least from the point of view of users. I hope that you understand the basic usage by reading this article. This article is only a basic tutorial of Ray-MMD. To go further into Ray-MMD, you need to refer to the other parts of the documents.

Ray-MMD, like other rendering engines, is a linear color space rendering library that works in the high dynamic range, so you may need to understand the meaning of dynamic range, as well as the sRGB gamut and Gamma correction. This knowledge may help you understand this and some other rendering engines better.
