Let's just say, it's my legacy. If you are a pro MMD user (or Blender user), then there is nothing interesting for you in this video. This video is just a tutorial for those who want to improve their videos at least a little bit.
If you don't want to search for those files for your MMD with MMEffect. Here's link to RAR file with Raycast and those 4 effects - https://www.mediafire.com/file/rxqmhtam9hfjkuf/Ray_MMD_1.5.2.rar/file
RAR file also contains a written manual in English and Russian. If the video didn't make it clear.
Ну а для наших ребят, если хотите, то у меня также есть русская версия PMX Editor. Если хотите, то вот ссылка: https://www.mediafire.com/file/i1kikdd2w0w0s5i/Russian_PmxEditor.rar/file
