Description

Water setting Reflection Wavelet Scale is no longer functioning.

Expected behaviour: https://gyazo.com/8c27db224dbd3dd80e40ec4d0e07e9df
Current behaviour: https://gyazo.com/5bb3f399b9b342dc759024e064681b9c

Likely regressed with GLTF.
Issue exists on 7.0.1.6894459864. No repro on late 6.6 viewers

Reproduction steps

1. Set Environment to Midday and enable Pause Clouds
2. Open a new Water setting
3. Set Fresnel Scale to 0
4. Alt-cam to an area where clouds can be observed in the water reflection
5. Adjust Reflection Wavelet sliders

Reproduce the issue with Midday, Pause Clouds, a new Water setting, Fresnel Scale at 0, and the Reflection Wavelet sliders, comparing the expected and current screenshots. Trace the water reflection rendering and the suspected GLTF-related regression; done means the sliders visibly change reflected clouds and behavior matches the expected result.
