In VRoid Studio, you can adjust layer opacity in the Texture Editor.
However, the 3D view does not support semi-transparent display.
What you see in the 3D view is based on the final opacity of each pixel, calculated from all visible layers.
Pixels with 50% or more opacity are shown as fully opaque, while pixels with less than 50% opacity are shown as fully transparent and will not appear.
This means that even if you make a part semi-transparent in the texture editor, you won’t be able to see through it in the 3D view.
Below is an example of how the hair texture looks when adjusting a layer’s opacity from 0 to 100.
Layer opacity settings can be useful when editing textures, but the final display in the 3D view will always follow this binary rule.
Here’s another example using multiple layers.
- Layer A: Brown texture with 100% opacity
- Layer B: Red circle with 30% opacity
- Layer C: Blue circle with 30% opacity
Where Layers B and C overlap, the combined opacity goes over 50%, so that area appears opaque in the 3D view.
Where they don’t overlap, the opacity stays under 50%, so those parts are invisible in the 3D view.
If you turn on Layer A, which was previously hidden, it adds to the combined opacity, and the areas of B and C that were invisible before may now appear as fully opaque.
