I know I've read about this before but I can't remember the sol'n. What's it mean when you get a msg when rendering that says something along the lines of "No Ram for Bitmap"?

Yo' Wade: FWIW, my CIS id changed a few months ago, your message is to my old address. "No Ram For Bitmap" can mean that in loading the maps required to render a scene you have already run out of RAM. You didn't even get to the point where you'd normally see "Rendering in Progress". One possible quick fix is to disable Texture Map Filtering as it uses an additional amount of RAM to perform this action. Another is to avoid rescaling a background bitmap. To free up RAM for other maps I would suggest using Raytraced Shadows as this may make the difference in being able to render the scene (albeit slow) and getting the error message. As long as I'm spewing, there is NO RAM savings if you change 24 bit or 32 bit maps down to 8 bit. Maps will always take up RAM with the same formula x(in pixels) X y (in pixels) x 3 bytes. So, a 32 bit tga at 640 x 480 will take up as much space as an 8 bit 640 x 480 .gif. These RAM allocations are spelled out in detail in the Installation guide. BTW, I caught some seriously cool 3D weather animations whilst in Hawaii. The mountains and volcanoes make the fly-bys under the clouds and around the islands pretty exciting. Your work possibly? – Bob Ritger

>> id changed << Thanks, I got your new one: 73041,3173. It ran in my mind there was a more complicated sol'n; glad it's just basic mem allocation. This was one of our clients' problems; my reboot suggestion probably worked then. Re: wx flythru in Hawaii. Not mine. Probably the competition's SGI base system. You can catch ours in Miami, San Diego (Hi Alan), El Paso, and some smaller markets in the SE. It's picking up some steam though. Hopefully we get a client in Hawaii; I'll volunteer to do the install. Later.

Hi Wade<g>. Which SD channel is running your stuff? -Alan

KGTV; not sure if it's NBC or what. They went online in July or beginning of Aug. Not sure; they were in test-mode for quite a while.

I'll look for it… -Alan
