Maxwell: error: An unexpected SEHException occurred. (caller=Render)

I get these error when trying to render large scene in Rhino. Mesh transfer gets to 60% and then this error?

[JDHill]

The only times I have seen this, it has been due to an out of memory scenario. Since you say it occurs during export, rather than rendering, I am going to guess you are using either Rhino 4 or Rhino 5 x86, and that if you monitor Rhino4.exe in Task Manager, you will see memory getting into the 2.5+ GB range near the time of the error. Does this seem to be an accurate diagnosis?

[richardfollett]

yes. Rhino4 and error occurs when rhino at 3.2 GB

So is the file just to big to render?

[JDHill]

In a 32-bit process, yes, but provided there is enough physical memory (and a 64-bit OS), it should work fine in Rhino 5 x64.

[richardfollett]

ok. So I tried a test in rhino 5

I downloaded the latest plugin version 2.7.22 and installed ok. But when I try to switch to Maxwell render in rhino it says

Unable to make "Maxwell for Rhino" the current render plug-in

Is this because I am running a demo version of 5.0 ?? (no save options)

[JDHill]

I believe that when a Rhino trial expires (that would be indicated by save being disabled), it will no longer load plugins.

ok, thanks JD for your time
