Screen Space Reflections

Screen Space Reflections

Generate screen space reflections for reflective surfaces.



Method #

Generate screen space reflections (SSR) for objects in the scene. To see this function, “Reflections” must be enabled in the objects material node or section.

The material nodes Roughness attribute defines the clarity of the reflections, with larger values being both more blurry and less efficient to process.
Link an environment map into the SSR to add it to the reflections.


These properties control the core behaviours of the node.

Minimum View AngleReduces the angle of reflection on objects in the scene.
Step SizeDistance refection are sampled at.
Envmap BrightnessHow bright the output environment map is.
Blur SamplesNumber of samples taken to improve SSR accuracy.
Use Normals For RestrictionAdd normal information to the SSR.
Animate NoiseAdd animated noise to the SSR.

ActiveEnables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.Envelope Modifier
