RT - Track mouse issue

[talleman]

Vladimir,

I noticed a problem when rendering with vray rt. When the track mouse option is on, and the mouse is not within the vfb, the rendering stops.
Not really a bug, but it could cause problems if it is accidently checked.

I think it tries to clear the noise just at the edge of the VFB, which is closest to the mouse pointer. I think there was a discussion about this in V-Ray for 3ds Max.
But I don't know what was decided. It happens to me a lot, I forget the "follow mouse pointer" on and think RT is running slowly, when it is actually clearing the noise
only on a small part of the image.

Greetings,

The way Modo handles it is a really good example. it actually has track mouse on all the time, and whenever the mouse is out of the frame buffer, it updates the whole image. if the mouse is within the frame buffer, it tracks it.
I don't know how easy/hard that would be to implement.
