GI Corrupt ....

[akshayarora]

Hi all,

 

Attaching a usual problem occurs in most of our animation projects ,

 

As a solution-we use to re-render these frames with a matte of that particular object like ceilings in attached frames.

 

Does anyone has perfect solution such that we get rid of this issue for further animations.

 

Thanks..

Seems like no one in interested to reply in my threads

 

I have posted 3 queries and didn't found reply on any of the thread.

How are you rendering your GI?

 

You have to set it all up differently for an animation than you would a still....

Dear Sir,

 

Thanks for your revert,

I am posting screenshot of render settings,you can have a look.

Your settings are a bit odd, but I wouldn't really say any one of them are the root cause of the problem.

 

How are you pre-calculating the Irradiance Pass and the Light Cache?

 

You can actually do them both at once. Just set the Light cache to fly through when you run the IRR and keep a reasonable nth Frame and use multiframe incremental.

 

It is important that you render this pre-calc on a single workstation too...

IR preset should be set to medium animation

try this reset you are vray setting

Dear Sir,

Thanks for your revert,

We used to keep IR map to Incremental save to current map and LC to flythrough while calculating GI .Also ,we calculate this GI on a single workstation .

 

Actually am unable to trace the issue because on a same settings ,sometimes problems occurs and sometimes not .

Any other reason ??

This i will try in this file . Thanks

If you are only rendering every 10 frames, for example, when calculating irradiance map then for fast moving sections this may not be enough. That is where you will get missing areas which show as artifacts. You can manually add frames to the saved map or just render with a smaller number of "nth frames" in the first place.

We use 3 as a Nth frame while calculating IR map.
