Greyscalegorilla Redshift Materials Today
If you apply a "Brick Wall" GSG texture to a tiny phone case, the bricks will look microscopic. GSG materials are usually built at 1-meter scale. You must go into the -> Texture Manager and adjust the "Scale" parameter (usually located in the GSG custom attributes UI) to match your scene units.
Metal is notoriously difficult to render. It requires complex Fresnel effects to look right. The GSG Metal library includes everything from brushed aluminum to rusty iron. greyscalegorilla redshift materials
GSG Glass materials often produce caustics. While beautiful, caustics increase render times. If you are doing a animation where glass is secondary, open the material node editor, find the "Refraction" tab, and disable "Caustics." Or, switch the "BRDF" model from GGX to Beckmann for cleaner highlights at lower samples. If you apply a "Brick Wall" GSG texture
