Feature suggestion

It would be nice if you could coose an area of the image to concentrate the calculation there. You could also variate the area in real time during rendering...

It is a problem when you have a specular material only in one area of the image. PMC doesn't get to calculate darker zones and pathtracing lasts a lot to get the caustics. For examle: a fountain

don't know what do you think about this

A region render and/or a render brush would be very welcome. As you said darker areas generally need more time, it's a huge waste of resources sometimes.

Hi,

A render brush would be nice, we may see what we can do in the future.

The bright noise in the posted image looks like there is a problem with the geometry. Does the noise appear with smoothing turned off?

And a general remark: if there is a problem with nose, it is much easier to see what is going on if hotpixel removal is turned off (set hotpixel_removal to 1.0).

Hi

The bright noise is normal since I have several lights in the scene arround the fountain, and as it is a bumped-water-map I think it is not a problem.
Yes, there are two faces that seem to have wrong normals in the fountain, I hadn't time enough to correct geometry

my wish that, I can put small light emitter together with wide light emitter without any fireflys
