# Smooth normals Controls how object normals are smoothed, adjusting the transition between sharp and soft shading across surfaces. The angle setting, which defaults to 40 degrees, controls the transition between sharp and smooth shading. A value of 0 preserves all hard edges, while increasing the value progressively softens them, blending the shading across adjacent faces. {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://help.vectary.com/documentation/design-process/design-mode/setup/smooth-normals.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
