#Can't render TGA file

I am trying to render a series of Targa files to be sent to a film recorder for slides. I have the resolutoin set to 4096×2731 with an aspect ratio of 1.23 as recommended in the film recorder documentation. I am rendering to Null. When I try to render I receive 2 messages… Can't Allocate Image Buffer and Init of Driver Failed. I've got 24 Mb RAM and I think enough hard disc space for the image, though not a great deal left (about 7 Mb). What do I need to do to resolve this problem? Thanks in advance, Chris Barnes

Hate to say this, but your error message, "Can't Allocate Image Buffer" and "Init of Driver Failed" is a sure sign of insufficient memory! I bet if you decrease the resolution of your image from 4096×2731 to a much lower value, it'll work. You might enjoy <g> experimenting with different resolutions to see what the threshold is for that particular image. Count on freeing up some disk space, many megabytes, to get this to work. You might even get this message with 40 megs disk space free, for instance, depending on the image (texture maps add overhead for instance). Nik

Ouch! I was afraid of that. Thanks for the swift reply. At least I have some fun experimenting to look forward to <g>. Chris

Chris, Don't forget to set Save-Last-Image to NO, since this takes up mucho disk space (and is uncompressed). That's about 34M just for that image. Add your resulting .TGA file (which you should probably handle as compressed if your film recorder will accept it). My guess though is that you still do not have enough RAM for the total of geometry, textures, shadows, etc. You will find info in the manual on how to calculate the necessary RAM.

In addition to the other replies, take a look at 3DSRAM.DOC in DL3. It'll give you an idea of how various components in a scene use memory. – Jack
