# setDepthBias(_:slopeScale:clamp:) Configures the adjustments a render pass applies to depth values from fragment shader functions by a scaling factor and bias. ``` func setDepthBias(_ depthBias: Float, slopeScale: Float, clamp: Float) ``` ## Parameters `depthBias` A constant bias the render pipeline applies to all fragments. `slopeScale` A bias coefficient that scales with the depth of the primitive relative to the camera. `clamp` A value that limits the bias value the render pipeline can apply to a fragment. Pass a positive or negative value to limit the largest magnitude of a positive or negative bias, respectively. Set this value to `0` to disable bias clamping. --- Copyright © 2026 Apple Inc.
