Slow Render Selected

Corona Corona for 3ds Max Issues
1

Hello,
I have experienced odd behavior in Corona.

  1. Render Selected Mode - Viewpot Selection
  • Render of the object took 5 min
    1. Render Selected Mode - Viewpot Selection + Region in VFB
  • Render of the same object took 9 sec.

This is quite ground breaking. I have tested it several times, works like a charm.

2

Even if you set the region to be the whole view?

3

do you have huge render resolution and small render region? In that case it would be expected

4

Not huge, but yes the region is small same as the object selected.

I have checked this. There is something funny going on indeed, but I cannot tell if it’s a bug or something expected. I wasn’t rendering in huge resolution, but the scene was pretty heavy (lots of proxies outside - trees and grass). I can check this with other scenes.

yes, this is expected - there is some extra work to discover the pixels that need to be rendered. This is done even for pixels that end up not being rendered

7

Would it be possible to make Corona internally do a region around the selected object?

8

My question is, will region+slected method result in crashes? Or its a proper way?

9

yes, some optimization is possible in the future
