Krakatoa 2.0 works fine (Max2012-Design, Win7-64), but if i try to load saved file, I dealing with the problem – " An error has occured, bla bla…"
What to do? it may be worth to save a scene switch to standard renderer instead of Krakatoa? (Because while starting Krakatoa GUI I encounter non-fatal error)?
Please, when reporting errors, try to write in short steps that help us follow exactly what you did. Knowing what objects you created in your scene, what modifiers (for example Magma) you used etc. could be vital to debugging the problem.
Also, posting the exact version number of your Krakatoa build would be very useful.
Then, zip a simple saved scene that crashes for you so we can try to load it and see if it loads on our machines.
And when you see an error message, do a Ctrl+C or PrintScreen and paste the EXACT error message or an image of it. If anything is printed to the MAXScript Listener, be sure to also copy and paste it here.
I have not seen this error before, so please don’t assume we know what you are talking about 
The " non-fatal error" about which I wrote earlier was " error start krakatoa GUI" when I tried to start one from toolbar, then I just switched to Krakatoa in Render Setup, and everything was OK. My guess was correct – switching to Scanline before saving file solved the problem.( I’m afraid this is due to MAX-own bug, one`s ScriptListener works incorrect, for example)
Krakatoa 2.0.1.46319
This is still not good. We should figure out why you are getting this “non-fatal error” and fix it.
I would not blame Max in this case, there is something wrong with your setup.
Btw, you should never set Krakatoa as the “default renderer” in the Render dialog, or save a MAXSTART.MAX file with Krakatoa set as the default renderer, since the loading order of Max was changed at some point around Max 2008 and the scripts are not initialized yet when these attempt to assign the renderer.
But if you try to assign Krakatoa from a MacroScript on a toolbar or from the Krakatoa menu, an error, even if non-fatal, is not something you should be getting.
If there is ANYTHING in the MAXScript Listener after launching Max or when opening the Krakatoa GUI, please post it here. If a script editor opens at a certain line, tell me the line number.
Also, you should switch to at least Krakatoa 2.0.2.46508:
thinkboxsoftware.com/krakatoa-downloads/
We also have some more recent 2.1.x builds in the Beta folder:
thinkboxsoftware.com/krakato … ilds-beta/
the fact of the matter that the listener does not display ANYTHING! clip2net.com/s/2mFCo
Meanwhile krakatoa lanches OK from the second time . Ah! Again nothing! clip2net.com/s/2mFI1
Thanks!
I can see where the error is thrown and might have to give you a special version of the KrakatoaGUI.ms that prints something to the Listener so we can understand what function inside the openGUI() call is causing this Unknown System Exception.
