Comparison

All code has been rewritten and optimized in the Lightweight RP version.

Mode	built-in RP	Lightweight RP
Performance	Slower	Faster
Lighting style	Pixel	Pixel, Flat
Fron Side Lighting Module	UnityPBS	Blinn-Phong, SunShine
Point Light	Built-in method	Blinn-Phong
Reflection	Planar	Color, CubeTexture, Probes
Under Water	Simple	Advanced

Known problem

• Refraction consumes too much performance, unless the water does not receive shadows, In Lightweight RP, transparent objects can also receive shadows (limited), and opaque texture is relatively cheap to obtain.
• In order to achieve refraction offset effect, need to use camera to render the camera depth texture of water. In Lightweight RP, only one pass is needed.
• In Unity 2019.1.0f2, shadow display is incorrect.
