[Bug Description]
You can see the bug at the place of the white arrow on my title image. Part of the hair disappears behind the solid body silhouette. (I used a PH snapshot here, but HS is the same)
[Easy Solution]
(May lead to weird texture problem, if you use a different version of uncensored mod or don't use any uncensored mod)
If you think this bothers you and likes to use semi-transparent solid body in HScenes, the easy way to solve this is download my cm_base.unity3d file from the following link, and replace the original HS file with it. REMEMBER TO BACK UP BEFORE YOU REPLACE!
[Cause]
The cause of the problem is that I changed the sorting order of hair strands, in order to get the hair transparency straight. But the sorting order of the body silhouette is 0, and so it will be rendered before hair strands with bigger values. I spent nearly a whole day to understand the relationship between sorting order and render queue and so on, and then solved this problem...
[A More Recommended Solution]
If you're afraid to mess up with your HS system file, you can try and download a version of SB3Utility from https://github.com/enimaroah/SB3Utility/releases
(quite useful, you'll definitely make use of it in the future if you want to successfully install my future PH mods)
And then open the app, drag cm_base.unity3d from folder abdata\chara into sb3u, double click on p_cm_body_mnpb, expand the Object Tree to the following SkinnedMeshRenderer and change the Sorting Order to 200. Save and done. Learn to use it, you'll never regret about it.

[Thanks]
Thanks to my patron Ling-Tim Chow for the bug-reporting. I didn't notice this myself for nearly 3 months of modding...
If you still have problem with this bug, let me know.
