To reproduce:
1. Open [Particles]FTP project from the Collab (smaller project version in progress);
2. Open "18_LightsModule" scene;
3. Change Graphics API to OpenGLES3;
4. Build and run on iOS and Android devices;
5. Repeat with OpenGLES2.

Expected result: lights are rendered correctly.
Actual result (see attachments):
-Lights are missing or rendered incorrectly (Samsung S9+, Huawei 6P, LG G4) - OpenGLES3,
-Lights are pixelated (all iOS and Android devices) - OpenGLES2.
