Render time / ETA

[hall]

Any chance to get ETA from mantra? In my case its important when you are rendering still image using 4k up resolution.

you can use the pre-render/post-render scripts on the mantra ROP...

it's clumsy but it works

[lukeiamyourfather]

Coming up with a meaningful ETA for a render in progress is pretty much impossible because the time required to render each bucket can vary wildly from a fraction of a second for an empty bucket to several minutes or more for a complex bucket.

Using a proxy render would give a better ETA, for example rendering something at 1/8 resolution and then multiplying that result by 64 for the full resolution. It won't be exact but it will be close.

opps..

sorry I though you were asking for a way to measure the time of a render...

[Guest tar]

Perhaps non-adaptive sampling could make it more predictable too?

[hall]

michael, yes you are right, when you refers to pre-render/post-render script,..is something ike this? http://www.sidefx.com/docs/houdini13.0/render/python

I noticed the parms for render completion per bucket. sounds cool!

 

But I'm really new to implement that, I'll research more about.

 

thx guys!
