Transparent glass makes other transparent parts not render

[bloodbonniekingnoob1 (Brutus)]

Reproduction:
create a part, change its material to glass, and make it transparent, but not 1. make another part, make it transparent and look through the glass part. it won’t render. any other material other than glass will. Here’s an image:

We’ve filed a ticket into our internal database for this issue and will start investigating, we will update you when we have further information.

Thanks for flagging!

This is a known issue and an intentional limitation, unfortunately:

@Homeomorph

Warning: Non-opaque Objects - Non-opaque objects are currently not visible through glass. This includes, but is not limited to, transparent parts, decals on transparent parts, particles, and world-space gui objects. This behavior matches the refraction on high quality smooth terrain water. This was implemented so refraction wouldn’t have a large performance impact. This behavior may change. We do not recommend relying on this behavior for gameplay.

Because it is intentional, I think that you should instead support this feature request:

Make glass work with transparent objects

As a Roblox developer, it is currently not feasible for me to use the glass material in my games, because the material does not work with other transparent parts. For example, if I place a part with 0.5 transparency in front of a glass part, the transparent part will be invisible. This so-called ‘bug-feature’ of the glass material affects particles, water, translucent parts, UI, and all sorts of visual effects and transparent objects in the engine. In some Roblox games, this may be just a mino…

I mean yeah but originally it was done so that it wouldn’t have large performance issues. Since the release almost 7 years have gone by, technology has changed. So I am hoping to see this change too.

[bloodbonniekingnoob1 (Brutus)]

unfortunately, it hasn’t.

The issue occurs if the front block (the grey one in your picture) has the material set to Glass. It hasn’t been fixed yet sadly.

It’s not just parts. Particles from particle emitters won’t show through glass either. So for right now, I think the best thing to do is to avoid using the glass material, unless you have a specific requirement that needs it.

got trolled ig sorry dude for spreading false info

This is a known limitation at the moment, as it was pointed out. We know there is a feature request to support the transparent object. Unfortunately that’s not something we’re currently focusing on.
