Can we mask pixels to be rendered?

[osylum]

Hi,

I saw that there is a crop option to render only part of the film. As well, from https://mitsuba.readthedocs.io/en/latest/src/rendering/scripting_renderer.html, it would be possible to create custom rays that are emitted for selected pixels. How can I select pixels to be emitted while re-using existing sensor and integrator?

Thank you

Hi @osylum

This is currently not possible. You would need to write your own custom sensor. It should just be a matter of copying an exisiting one and adding a mask that is exposed.

ok, I'll do that then, thank you
