How to Render Only Part of an Image With Cinerender in Archicad

This is very useful if you are working on materials/colors/lighting/reflections. Helpful too, when your client comes back with small material/color changes, so you don’t have to re-render the full high-resolution image. You just select marquee tool and define the Marquee area.

Now from photo Render setting ( it is available at document/ creative imaging/ photo render setting) select render marquee reign.
