I've exported a terrain file from Terragen as an .lwo file. Everytime I try to bring it into Bryce 4, it gets the polygons loaded 75% before telling me "an unexpected error has occurred (out of memory)". Anyone have any idea what's going on?

you ran out of ram

I had the same problem trying to import a 35M obj file into Bryce 5-I have 256M of RAM- on the same machine with only 128M RAM I could improt obj files over 40M with Bryce 3 has anyone else had this problem?

I've had similar 'out of memory' problems with even simple objects that were made in other programs. One thing I found was to run them through Metasequoia and do a check on open mesh or overlapping mesh, or non joined mesh. When the errors are fixed, the object comes into bryce just fine. You might want to check that out.

well if I make it a 3ds(which is about 10M) it works fine. this is the same object just a different format

I have plenty of RAM. Terragen claims it is a 2meg file, but I think it is larger. I don't have any way to make it 3ds file, I can only export as a Lightwave file. I've never had problems with large .lwo files before though. I'm wondering if Terragen itself is at fault. Ah well - despite Terragen's appeal, I still like Bryce better.

I am not having the problem with Terragenn files(I've never exported anything out of Terragen) its just large files in general I guess...

Remember that alot of 3D files expand tremendously in RAM when they are loaded. The file size megs and RAM usage megs are not a 1:1 ratio. I have over 300 megs of RAM and can still run out of memory with really complex models that have a fairly small file size.

Are you running Windows 95/98? I find under Windows 98 that I can only load a model no larger than 15-17 meg in .obj format, And ME seems to be worse. 256 Meg on a 850 Mhz laptop made no improvement in maximum loadable filesize. Under Windows NT, The limit is more like 120 Meg (with 128 Meg of RAM)(I successfully loaded 117 Meg Onyx tree model, failed at 135 meg...) Bryce 4 is better than Bryce 3, and I haven't tried to find the limits yet in Bryce 5, mostly because Bryce 5 has native trees with real curved leaves.
