Final Gather Map
show user profile  Coxy
Hey guys,

I am trying to render out an animation and I clocking up a final gather map for 600 frame of 26gb. I never remember the file sizes being this large in the past. I have been given the model of a colleague to work on. Is there anything that could be causing such a high file size? I am sure I remember my FG maps in the past being a hell of a lot smaller.

Is that containing one FG map for each of the 600 frames, rather than one single one?

It is a single file only accumulating FG in 10 frame intervals. Should I be doing one file per frame?

I am not really sure, to be honest. I never really save the maps!

But, max suggests that for animated object scenes, to use one file per frame, and to use one file only for stills and walkthroughs.

Well only the camera is moving in this one, so there are no moving objects etc. In the past I swear I only hit 100's of MB of file size for these maps, yet for this model I am hitting double digit GB files..

I have been given this model too and it is horrific, I don't have time to remodel it all and I have a short time deadline to get this animation done. But, with a 26GB FG Map file, the computers seem to be crashing every time I try and use it. I could try and split it up a bit I guess.

For no moving objects, set it to use a single file throughout. I imagine that the difference in your file size is relating to his setting.

Well, I have set up all of the Final Gather in his model and redone the lighting and presentation. It is only using medium with a high noise filtering. I think I will try doing separate files for each camera view rather than using a camera switcher.

Ok I found the issue. Autodesk has changed the Final Gather Map map container solution from 2011. It now takes long and makes massive files. To fix it you can download this plugin which will allow you to use the old 'Legacy' method. Or you can just render your FG maps in 2011.

Blimey, I had no idea they had changed it for 2012. Those files sound ridiculously massive. Thanks for the update.

I think there might just be a bug in it now where it rebuilds everytime and cumulatively adds the data. Looking at how it stored my data it would increase by multiples everytime it saved a file. So it would start at say:

11k 1st frame
33k 2nd frame
75k 3rd frame
125k 4th etc

All the way up until 20 odd GB of file space just for a 600 frame animation...
