The Sketch Engine in Archicad is a feature enabling architects and designers to produce freehand sketches within the software. You executed the render, but the outcomes appear grainy and low in quality.
Solution
If your Archicad Sketch Render looks low quality, there could be several reasons behind it. Here are some potential causes and solutions:
Render Settings:
Resolution: Ensure that the resolution settings are high enough. Low resolution can make renders appear grainy.
Paper Settings: adjust the paper roughness setting to improve your render quality.
Anti-Aliasing: Ensure that anti-aliasing is enabled and set to a high level to smooth out jagged edges.
