Closing the VFB takes forever - why ?

[nirsul]

It happened in 2.4.x and now in 3.x - In the beginning everything is great but now everytime I close the VFB - it may take between 10-30 seconds !
Why ?

Is there a cache that can be deleted ?

Are you using the Nitrous viewport?

Yes

Shouldn't it be working with it ?

I have also found that the VFB can get very slow after renders finish, when you go to clear the buffer and when you want to close the VFB. I hope you might be able to speed these processes up if possible. I'm also using Nitrous. 2014.

Try to disable "Improve Quality Progressively" under Display Performance of Viewport Properties.

OK
I tried it but it does not help - Actually it took a bit longer this time

Ok; I'm working on some code that handles the VFB UI differently; it's still experimental, but it might help for such cases and hopefully will go into one of the next updates.

Sweeeeeeeeeeeeeeeeeeeet, Vlado is #1

Hehe, we'll see. The way this experimental stuff is now, the 3ds Max UI remains active during rendering, which, while maybe useful occasionally, may also lead to unexpected problems, f.e. if you change a material during a render or go to File > Reset...

You mean that we can continue to work on the scene, tweak materials and other settings while rendering? This will be extremely beneficial!

Nonono. I mean that you can click on things that you shouldn't F.e. if you change a material, it will change how the rest of the render comes out (or crash, depending on exactly what you changed).

If you want to fire a render and continue working, simply use backburner, or make a script to fire a 3dsmaxcmd render.
