3d-printing Glass

i stumbled up on a problem when 3dprinting glass:

On the right side is the original glass and on the left side the 3dprint. It completely loses the tint of the colored glass.
Then i tried to use the tint feature and:

it turns solid into the assigned color.

Is there another way to print colored glass or is the losing of the tint a bug?

So, here's the issue: Based on existing data alone, I can't figure out if a texture is translucent or not - and this is significant for Minecraft's rendering system.

There are two ways to solving this:

• (a) Extending the 3D print format to include the "render pass" on which a given texture rests; "solid", "cutout", "cutout_mipped" and "translucent" are the four passes in 1.12, and 1.7 has two ("solid"/"cutout"/"cutout_mipped" constituting the first pass together, in practice).
• (b) Scanning textures after resource reload to figure out which ones have translucent pixels on them, and dividing prints into render passes automatically.

Requesting feedback!

i am not sure what would happen if you would use implementation (a) and then for example use stone texture and "translucent", but otherwise i think both implementations sound reasonable

Nothing in particular; but using "glass_brown" and "solid" would not work right, for example :P

then i think implementation (a) would be superior as it would give players more freedom for what they want, for example if someone wants the non transparent glass that would still be possible (as far as i understand) also how would this interact with the tinting feature?
