VFB, Max Render Window, and V-ray Lens Effects inquiry

[Javadevil]

Okay,
I don't see what the purpose of not being able to apply the Lens effects after rendering a FINAL.
So this means I have to have it setup first, then set off the FINAL render.
I'd like to tweak it after I have render I high res.

cheers

Hi,
I'm wondering why sometimes when i update the effects it starts rendering all over again and other times it just updates the glare/bloom which I want.
How does it work ? Do I need to have the effects window open before I hit render ? or has it nothing to do with that ?
My steps are,
Add Vray effects
Hit render
open the effects window
make changes to get the glare effect I'm after.

What would make it rerender the scene ?

best regards

From what I understand, you need to first open the Effects window, and then do the rendering. Then the interactive mode should work as expected.

The lens effects require some additional information (i.e. the original image colors, before any color mapping or gamma correction). Especially for a high resolution image, this information takes quite a bit of RAM. It makes no sense to keep this data around every single time, just in case you want to apply lens effects afterwards. It's all about using RAM efficiently.
