help with animation error

[pg1]

I am doing a series of animation at 720x576 using a pre-calculated irmap

medium animation 50 hsph and 20 interp. samples

and qmc with 8 subdivs and 6 secondary bounces.

Adaptive qmc for antialiasing at default

 

The noise threshold is 0.006 with the rest of the rqmc settings at default.

 

I am getting a error on random frames that looks like a fingerprint smudge on camera lens.

 

I've looked through the backburner monitor to see if it was one specific render node causing the problem and its not isolated to one particular node.

 

Anyone got any ideas what could be causing this?

Doesn't look like a Vray error. Do you have render to fields on? It looks like the other field wasn't rendered.

Thanks for getting back to me

finally pinned it down x-dof (a post render plug-in) was the culprit

switched it off and haapppppy days looks like I might actually get to go home tonight

Glad you found your problem....a few beers for you tonight !!!

 

That rendertime of 17 minutes seem very high for your scene. I recently did a similar scheme (ie minimal reflections, no displacements etc) and it was weighing in at 55 seconds a frame.

 

Granted it was pretty straight forward, but it was full GI, some bump mapping and raytracing, but like I said , rendered in under 60 seconds a frame on a relatively modest hardware setup. (which for a 2000 frame animation was a blessing !!!)

 

Are you using IM and LC ?

Hey martin

 

I did have a few beers last night and back at it again today.

 

The reason the render time is so high was because of motion blur which I also switched off and a large no. of forest trees (planes scattered around with a diffuse and an opacity of trees)

 

I eventually rendered the trees in a scanline pass and got the render time down to 3 mins a frame
