Merge VRimage and Compositing technique

[jlaucks]

I have found Damien's recent tutorials on both Large scene rendering and composting very useful. Thanks Damien!!

The latest project i am working on I have successfully used the vrimage to avoid crashing. but now I am curious if there is a way to use the composting method for better rendering post processing but with the memory conservation of saving to VRimage?

Has anyone tried this or figured out a method to composite images in the range of 5000 x 2500

Thanks in advance!

Re: Merge VRimage and Compositing technique

Glad you liked the webinars...at the end of the large scene webinar I talked a little bit about converting VRimage files and how to set that up. I showed the easy way, and mentioned that there was another, more complex way of converting them. In this case you HAVE to use that hard way, since that will be the only way you will be able to access all of the channels you will need to composite. All the channels are in the VRimage file, but you have to run the converter manually in order to get them. Check out the following page from spot3d, fire up the command line, and try and get the channels converted. Its relatively straight forward, so give it a try and if you run into any issues we can clear that up later.

Now the other thing that is going to make this process a PITA is that PS will probably choke on a full composite at that resolution. The amount of memory that's needed to keep all those channels will probably crash PS or at least make it run slow as a dog. I would certainly give it a try and see how it works on your computer, but wouldn't have too high hopes.

If you've invested in the process and workflow of compositing, then I think you may try and see if a full compositing solution would be more satisfactory for what you're tying to do. Applications such as AfterAffects, Combustion, and Digital Fusion are built to deal with these kinds of situations that will bring PS to its knees and they also are more workflow friendly than PS when it comes to compositing.
