HI there,No, there are no trial versions for any of our tools since there is no way of reducing their features into a trial version that can be offered at no cost. We instead try our best to keep them as affordable as possibleThe reflections of this asset work by rendering a copy of your scene through a new viewport using a RenderTexture or Shaders only. Because of this, it should not have any issues rendering objects with custom shaders as long as they do not depend on custom components attached to the main camera (custom buffers etc). Due to the complexity of what you want to achieve, you must use the render texture variant of the reflections. It is all explained in the included documentationAgain, since the reflection camera works through a Render Texture it is capable of rendering mostly everything that the main camera renders. It can reflect 3D objects and 2D objects without issues as long as the layers are set up correctly, and it is compatible with Post Processing (the reflection cameras themselves cannot have custom post process effects but if, for example, you have an object which should glow when using the bloom effect it will glow on the reflection as well).Many shaders are provided as examples and can be used to create your own custom 2D reflective shaders with ease.I hope this helps!
