When I try to run my level, it takes like 20 minutes to load, then before the initial splashscreen come up i get an error message saying "Cant open video card"...I only get it with this particular level, all my other levels run fine and dont give me this error.

My level has only one camera, one actor model, and 100 heightmap models. the hieght maps are designed to use LOD ( IE plate001_0, plate001_1, plate001_2, plate001_3) The different LOD models only have different skins, each skin being a lower resolution version. (plate001_0 skin is 2048x2048, plate001_1 is 1024x1024, plate001_2 is 512x512, plate001_3 is 256x256)

Why am i getting this error message?

Hi,
what kind of graphiccard (eg. GeForce or Radeon) do you use, and with which driver version?

i have an ATI Mobility Radeon 9000 - driver version 6.14.10.6444. It has 128 megs of video memory. Its in a Toshiba Satellite laptop and the drivers are proprietary, im pretty sure i cant upgrade them.

Im also pretty sure its not my video card that is the problem too. As i said, all my other A6 levels run normally, its just this one level with all the heightmap models that gives me trouble

Shure it's a noob answer but - I get this error if I start the engine two times....

Try to check your level nexus, I had a similar problem (different in way) and came across this question in the old GameStudio forums. Changing the nexus with this error fixed their problem, and I'd suggest the same to you.

change the nexus? thats interesting. I was playing with the nexus size at one point...if I made it too small i of course got the nexus too small error, but then when i made it bigger i got an out of memory error. I tried to pick a nice middle gorund, but then got the cant open video card error. I'll try fooling with the nexus parameter some more, maybe i just didnt find the right size before....

ok..i give up...ive tried a nexus of 100, 250, 500, 750, 800, 900, 1000. Ive tried setting clip_far to as low as 1000. no matter what I do the level doesnt load. If my nexus is under aboout 900, i get "cant open video device", if my nexus is 900 or larger i get "out of memory (0MB required)"

Is there some trick to setting up LOD? and what the heck is up with 0MB required?? that just sounds *really* odd.....
