1. Open the “SLU6.zip“ project
2. Open the “example_3D“ Scene
3. Observe the Game view

Expected result: 5 lasers are visible
Actual result: No lasers are visible

Reproducible in: 2023.3.0a11, 6000.0.38f1, 6000.1.0b6, 6000.2.0a3
Not reproducible in: 2022.3.58f1, 2023.3.0a10

Reproduced on: Windows 11 Pro (23H2)
Not reproduced on: No other environment tested

- If the Alpha is set manually, the lasers sort of become visible
- Non-zero value from a Split node into Lerp node’s B or T value will return 0
- Might be only
