I am getting quite a few 'Unknown errors' while doing very simple stuff. For instance, Insert a cube, and covert to another modeler, and i get the message. Importing a scene I might get it. Other times I can do so without errors. Is this a known thing that Eovia is working on to anybodies knowledge? This is with the latest update, BTW.

Very strange. Are you on PC or MAC and what graphic card are you using and have you updated the drivers? Ringo

I am on a PC. I suppose the graphics drivers could be updated. I'll try that, and then see if that helps. My graphics card is an ATI Radeon 9800.

Your card should be ok--just make sure you keep updated.

Reset your preferences to default and see if that helps.

This straight out of the box, no changing of any preferences. I will try that though to see if maybe something got changed inadvertantly. Thanks!

Actually, many people have said they have seen this, including myself, but they are so vague and if you have trouble reproducing and no log errors w/ specifics they are hard to pin down or report.How much ram do you have? Also do you have any 3rd party plugins?

Also, I would make sure you are not using ms drivers, but your card drivers.

I have 2 GB RAM, Athlon64 3500. Using ATI's driver. I can't reliably reproduce. It just seems to happen randomly. Occasionally, everything works fine for the complete session.

This is a pretty weird and VERY aggravating problem. C5Pro appears to be the most stable version I've ever had my hands on. I'm running on a laptop with an ATI card as well but it's a very vanilla card. Just a post to present some compassion on the issue. Previous versions have had their moments. The original metacreations version of C was the real master of madness for bugs (even after you applied the elusive and mysterious patch)! I got very lucky to secure a copy of the metacreations version before it vanished into the ether and then it was tough to find the patch on the net after Metacreations disappeared (thank you EOVIA!). I would definitely update your video drivers with ATI's latest stuff and also update Windows (if you haven't already). I'd also try to remember any other software you may or may not have been running since your last reboot. Just a shot in the dark but maybe something to think about if you're trying to track memory leaks (who knows). -Kix

I hope i will track down the problem. i have been using Carrara since version 2, and this is the first version that crashes on me. All others were rock solid. I still have C4Pro that I can use when I have to.

From my experience, Carrara5 really does need you to ensure everything is fully updated, it's been designed to work with those latest things. Especially Windows and your ATI card. If you havent recently updated you will find lots to download and apply.
That applies to the Carrara updates too.

This is a long shot based on your desc, but still worth doing if you haven't done it. One thing you should do just to be sure since you haven't indicated anything saying video specifically is fully test your ram. Sometimes only a thorough advanced test will show errors. Memt86 should be ran on the complete advanced options. It takes a long time to run. Let it run overnight. If it doesn't pass you can end up w/ intermittent issues. It can be slight timing or voltage(I mean slight)that can cause this. Regardless you should always test your ram thoroughly.

Hmm. That's interesting. I'm using an ATI FireGL 3100 with the most recent drivers, and Carrara has been pretty stable for me so far. My OS is WinXP SP2, with an Intel Motherboard and processors, plus 2 Gig RAM.
