render large image

[kevin miller]

As every newbie is bound to experience, I finally got my first MR "cannot create buffer out of storage" error message. I have done some research on this forumn and downloaded the script to do partial renderings. Have not used it yet but I did have a question or two.

 

1. If I convert some of the parking lot cars in my scene into MR proxies, will that help? I know it helps on rendering times and file size but it still gets rendered.

2. Would it help to render parts of the image by rendering only selected objects? An example would be to render out the building and parking lot in one pass and then the cars and 3D people in another pass, then composite. Not sure How to deal with shadows though.

3. I read I should make sure the bitmap image filter setting is selected under the Render settings under the preferences. You are suppose to make adjustments to this. Does anyone know what these settings mean or how they should be adjusted? I also turned on geometry cache since someone mentioned something about that as well.

4. The Zap Script seems lie a good idea but people have commented on trouble getting the separate renderings to merge/ join well. Any thoughts on this?

 

I am running core duo 2.8 processors, 4 gigs of ram, 32 bit vista prof, raid array hardrives and 2 video cards. I did strip out vista to its basics and used the 3 gig switch. I know a 64 bit system would be optimal, and it will be coming, but I have heard of this issue in these systems as well.

 

I am trying to render 4500 x 2200 pix, FG was set to 2 bounces and low, AA was 1-16., Mitchel filter.

 

Thanks for any help!

I'm not a MR user but I would suspect that converting your cars to proxies would save you some ram if you had those cars repeating more than once in your scene. You should also be able to use the "split scanline" option in Back Burner to split the image into strips, that will also save some memory.

You can also make objects with complex materials not visible to reflections/refractions. Not perfect, but that can cut down quite a bit on time.

MR proxies can do on demand loading, so if they aren't all needed at once, I would _guess_ that you could save memory even if they aren't repeated.

 

Need to turn off scanline and turn on bsp2 for that to be of use, AIU.
