No refraction effect on the glass material in Unified Lighting

Enabling the beta function “Unified Lighting” breaks the refraction effect on the glass material at the LightingStyle=Soft setting, which did not happen in Voxel lighting technology.

with Unified:

without Unified:

Reproduction:
1. enable Unified Lighting in Studio beta features;
2. set LightingStyle to Soft and disable PrioritizeLightingQuality.

System:
* Windows 11
* CPU: AMD Ryzen 5 5500U 2.10 GHz
* GPU: Integrated
* Memory: 8 GB
* Studio Settings > Rendering > Graphics mode: Direct3D11

Expected behavior

The glass refraction effect should still work as before to match the visual style before the update.

the refraction issue has been fixed but I noticed that Roblox now handle the glass shader differently on different graphics settings. phong shading is enabled at graphics level 3 for all materials except glass (it continues to use gourand shading until level 8). I noticed this today during a normal game in the Roblox client

The glass light reflections stopped working on my phone because of the unified lighting update, it doesn’t matter what the graphic level is.

It forces the level 1 graphics glass shading on any graphic level, the “high quality” glass shader/reflections is gone afaik, this occurs in any game and ONLY on parts with the glass material.

(The lag is due to screen recording, and the resolution is low because the file exceeded the 10mb limit)

I’m using a Redmi Note 13 Pro 5G, the Roblox app is up to date (V2.686.866)
