+title: Cubemap Reflection
+brief: This example shows how to use a cubemap to draw environment reflections on a model.
+scripts: cubemap.script, cubemap_model.fp, cubemap_model.vp
+---
+
+This example contains a game object with a model component in the shape of the Defold logo. The model has a special `cubemap_model.material` which uses a cubemap sampler to calculate reflections on the model from the cubemap.
