LOD creator CTD

[nz255]

Hi, I am trying to create LOD's for an FSX mdl which is animated, however whenever I import the mdl and click generate LOD and calculate, it fails and comes up with this

Object reference not set to an instance of object.

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.


How do I set an object reference?

Great tool BTW Arno!

Thanks,

Nick

Hi Nick,

Looks like you found a bug. Which object have you loaded? Maybe I can reproduce the error here.

Hi here's the file, just a modified version of one I got from the site.

Hi,

I think I fixed the crash, although I am not sure if functionally the LOD Creator is working fine on this object already (could be due to the animation). It is in the next development release.

Excellent, thanks Arno! :D
