Big problem w/ Flicker

[sedus69]

Plz check this video http://www.studio-explisite.com/flick/Pvitreout.mov

It is a supposed Finalised Render... AS You can See a BIG problem whit flicker... only on Some Tree (The Garden on the roof is perfect) and some other Trees To.

 

I think the problem comes from the fact that a Put a RECEIVE GI 1.3 To Most of the tree, All tree w/o Modifi Gi render GOOD...

Any Idea WHY !!! Vray Did a such thing ? Good Render on The original PC and all other Over Backburner didnot works.

 

NO gamma Correction I doubled check, No Lut correction, No adobe Gamma corection. JPG are Exactly the same.

 

Any Way With any Post Production software to Make it better ? like removing the Flicker of an Very Old Film.

 

For Now Put all Frame Back on render farm... Cool 3 day to throw away.

Have to check those 3500 Frame (many more rendering) to kept Good one and put to Bin others)

should be something like reuse GI solution turned on.

I am actually working with final render, but i'm sure that vray have the same function.

Basically you cant generate GI solution for each frame becuase it lead to flicking movie, but you should reuse GI solution frame by frame. I really recommened to save GI solution to scene as well.

I hope it will solve your problem .

 

good luck.

I found the problem, I did a Small Test not a 35 Millions Faces Test like the animation.

 

The VRAY PARAMETER GI modification related (1.0 Generate Gi and 1.0 Receive Gi) Are not send to BackBurner, It only Works if You launch manualy the scene.

Generate Gi was Turn Off, and receive Gi put to 1.3, Works well to reduce Time calculation and Add light to trees.

 

2 Test :

A - 45 Frames to backburner, Flicker Frame Only "Original" PC running Manager Is using the Gi related parameter

B - 15 frame s+ 15 frames + 15 frames -> throug multiple 3dsmax session, Works perfectly

 

In both cases Gi was precalculated and Saved over the network (every pc take the VMAP from the same location (\\192.168.0.200\Render\Test\Vmap....)

 

So I remode those parameter, Delete every frame failling, and send deleted frame to backburner... again !!

Fun to do with 3500 Frame...
