Only the rotation will affect the lighting, because of the nature of directional light requires shading calculations for the whole scene. The angle of each ray reaching the object is negligible and the rays will always be parallel to each other, so it is also called sunlight.ĭirectional light doesn’t take into account the coordinates of the light source and won’t affect the lighting effect when placed in any position of the scene. Translator’s note: for those wondering what lights are available in Raycast, there’s a translation below of the wiki’s list.ĭirectional light simulates lighting hitting an object from an infinite distance. Originally, surface lights in a 3DCG software are characterized by their ability to create soft shadows, but the surface lights used in Ray-MMD are very difficult to handle and don’t provide much benefit, so we recommend using point lights or directional lights.

If you’re unsure about the other two items, start by reading this wiki. This tutorial has no intention in replacing the original author’s.īy learning lighting, you’ll have more freedom in directing your videos, but it’s only for those who are confident that they understand how to use Ray-mmd, because it’s a pre-requisite and an additional part of understanding how to use skybox and materials. The translation was done with the aid of the online translator DeepL and my friends’ help. It was translated from Japanese to English by ryuu with written permission from the author to share it on my blog and add information. Every picture shown in this translation can be found in the original documentations on Iwara and GitHub. This compilation was brought together by the MMD community and contemplates ngreeed’s own experiences with fog and lighting usages.

Let’s get started? If you just landed on this tutorial for advanced MMDers and is wondering what the hell is going on, there are beginner Raycast tutorials in Learn MMD! Also, if you feel like reading more about rendering tips, I suggest taking a look at my other tutorial: advanced MMD rendering tutorial (and why you should care).
