Gris Swimsuit for Ver.R, this time fully colour customisable. Leg part uses the glowing RGB heels but adjusted to not having glowing parts and without an inside logo but still transparent.
Few notes:
By default, the transparent part of the suit uses a glass/plastic material, however, this material unfortunately has a lot of artifacts when the character moves around. One of the biggest artifacts is when the transparent part will look like it is clipping through the body but it isn't (I tested the transparent part with non-transparent material and no clipping occurs with body except for large FBS presets), as well as the fact that sometimes the material looks like it is overlaying on top of each other causing shadow occlusion issues.,
As a result of the unfortunate side effects above, an optional 'Silk' material addon can be installed, this solves the issue of the Glass/Plastic graphical artifacts but introduces its own graphical artifact of dithering and ghosting. Generally speaking, dithering transparency is akin to what silk might look like in real life, but due to RE Engine limitations, there is noticeable ghosting in motion (you can see ghosting on the stockings when you use my Serena Armour mod).
In short
Glass/Plastic:
Smooth, no dithering, no ghosting, gives a glass like transparency, but clipping and shadow occlusion artifacts,
Silk:
Rough, no clipping and shadow occlusion artifacts, gives a silk like transparency, but dithering and ghosting occurs,
Is the glass/plastic fixable?
Maybe, but I haven't had the time to look into it, there could be a setting somewhere in the material which can reduce the artifacts but I don't know and the time is not now, perhaps I'll try experimenting in the far future.
