rendering preview animation with IR

[rsi]

Thanks cecofuli, I'm used to work in exr with piz compression for nuke, and used to save stuff in h264, I was just searching for a way to throw my old grab viewport when I'm searching for cam, having the benefits of lights changes and materials and speed.

I'm doing some testing because I really like the speed vs quality of IR, but rendering a frame range in IR with a pass limit doesn't work, I was trying to get the same speed and quality result with a pass limit with the regular render mode. I assume it is the same engine (no conversion, IR vs RT), is there a way to setup the (MSI, Max ray, GI and light sample) to have the same result or am I loosing my time?

IR by default has lower GI/AA balance to increase feedback speed at the expense of rendering speed. By default, it's 1/4th of what GI/AA parameter is set to. You can change that by using string option in strings field of devel/debug settings.

Just add this line:
float interactive.giSamplesMult = 0.25
and set  the multiplier to whatever you want. If you have default GI/AA balance at 16, then multiplier of 0.25 means GI/AA value of 4 for IR rendering.

Rawalanche, are you sure? I can change PTS while IR is working. And I see the change.

As Rawa wrote. IR and regular rendering is exactly the same engine. I'm not sure but probably secondary solver runs at lower settings in IR too.

Yes, because it takes 0,25x samples you set. :)

No maru, I hadn't that line.
