FWsim Help & Discussion

Hi everyone,

I have been trying to get a 3d model from blender into fwsim with no luck. I continue to get this error message even if I’m just trying to import a simple cube.

Error message reads ‘Object reference not set to an instance of an object’

I have followed all recommended settings for exporting as a Collada.dae file but with no luck.

Any help would be appreciated.

Try to export to GLB instead, it worked for me

Hi,

thanks for your message.

Usually .dae files (Collada) should work fine - but sometimes there are problems with specific files.

Could you send me your .dae file, including the textures? I’ll see if I can get it to work.

(I will send you a private message with details where to send it)

Best Regards,
Lukas

Hi All,

I seem to have found the solution… like most times its something very simple ofcourse!

I was storing my models on a separate drive to the drive that FWSim is installed on. FWSim is installed on my C: Drive and my models were stored on a different drive (in my case D:).

Moving the models onto my C: Drive and then importing them into FWSim has so far fixed any problems I was having.

I thought it was in issue with how I was exporting my models or an issue with blender but nope!!! Just model location haha :smiley:

Thanks!!

Thanks for the update!

I believe this is the cause: There is a bug in the current version of FWsim: When you load a 3D model file from the root of a directory (for example, c:\my model.dae), then FWsim crashes. As a solution, please put the 3D model into a subfolder (for example, into c:\my folder\my model.dae).

This will be fixed with the next update.
