every first frame renders too bright

[miohn]

Hi,

have a big problem here (Version 3.05.1)!

I've set up an animation with serveral products on a turntable.
Whatever framerange I choose, every time the "first" frame renders too bright.
If I render from frame 100 to 300 = frame 100 is too bright
When I render from 250 to 550 = frame 250 is too bright
How can this happen?

Its not a big problem as long as I render the hole sequence on my mashines,
but when rendering on a farm, means, that f.e. every 5th frame is too bright and I have
light flickers during the entire animation.

Haven't recognized this behavior before.
Any idear whats going on?

Thanks
Mike

Hi Mike,
very weird and annoying issue.
It would be great if you could share a scene

You know what i say. Scene please!!!

cannot send the scene, because its too big and a ongoing project.
Maybe I'll try to extract parts, but this will take a while

Thanks! There's a bug as i can see. It's working fine if i copy to new scene and render. I'm looking for main reason.

I think i found the problem. First is that i need to know is it an old scene? Because there's a problem on deprecated parameter of octane render settings. Plugin refer to this deprecated parameter and calculate wrong structures. For example if you create new render settings and select "OctaneRender" it will be fixed.

Hi Ahmet,

it is in fact based on an older Scene.
Copying to a new Scene (this time I forgot that
workaround which I normally try first)
fixed it already.

Thanks much!
