Create a fake reflection effect


In this little tutorial I want to demonstrate you, how I achieved a reflecting surface effect - in this case a puddle.
This is a scene I made and people asked how the reflection is working:

I started with building a road with some cubes and added another cube with low opacity to represent the puddle.

The actual trick to make it look like a reflection is to have the same scene underneath the surface as seen here:

This is the the little demo scene I made for this tutorial where you can easily see what is going on:

Have fun!
