The Built-In Render Pipeline is deprecated and will be made obsolete in a future release.

It remains supported, including bug fixes and maintenance, through the full Unity 6.7 LTS lifecycle.

Sets the depth bias on the GPU.

This command makes a change to the render state. Use it in a

Pass

block to set the render state for that Pass, or use it in a

SubShader

block to set the render state for all Passes in that SubShader.

Signature	Example syntax	Function
`Offset <factor>, <units>`	`Offset 1, 1`	Draw geometry closer to or further away from the camera, based on the given values.

Parameter	Value	Function
factor	Float, range -1 through 1.	Scales the maximum Z slope, also called the depth slope, to produce a variable depth offset for each polygon. Polygons that are not parallel to the near and far clip planes have Z slope. Adjust this value to avoid visual artifacts on such polygons.
units	Float, range -1 through 1.	Scales the minimum resolvable depth buffer value, to produce a constant depth offset. The minimum depth resolvable depth buffer value (one unit) varies by device. A negative value means that the GPU draws the polygon closer to the camera. A positive value means that the GPU draws the polygon further away from the camera.
