# Reflective materials

Hology Engine supports reflections on materials through **Screen Space Reflections (SSR)**. This technique approximates reflective surfaces by tracing rays against the contents of the current screen, allowing for real-time reflections without the heavy performance cost of traditional ray tracing.

Materials’ **normal**, **roughness**, and **opacity** values are taken into account when calculating reflections, allowing for realistic variation across different surfaces.

## Enable reflections

Open the material asset from the asset browser and toggle reflective to Yes. It is by default set to No.
