Grimrock

The Grimrock 2 importer/exporter has been updated to work with Grimrock 1 as well. (.dat file is untested, otherwise it should work fine)
For anyone interested, head over to the mod section for Grimrock 2 and check it out.

Does this use 2.71 features, or would it work with 2.70?

Import works with 2.70. I´ve tested it with the tunnel_ogre model and the tunnel_ogre_attack animation from the asset pack.
But export works not for me.

Exporting [as you very likely know ~but for those that don't...] could be managed via John Wordsworth's GrimFBX.

I hope it's a minor thing, and not somehow 2.71 dependent; that might see it fixed in an update.

That's odd, I just tried it with 2.70 and it worked fine.
I brought it in to the GMT tool and it played fine there as well.
What kind of error do you get?

When exporting animation, be sure to select the correct format.
There's an 'Animation Version' drop-down to switch between Grimrock 1 and 2.

@Isaac: Yes I know it and I use GrimFBX for exporting.

@bitcpy: Thank you for telling me about the drop-down button in blender. After changing to "Grimrock 1" there are no error messages in the GMT after importing the animation file anymore.

After exporting from blender into a .model file and open it in the GMT there is no mesh data. Only the nodes are viewable and they are rotated through 90° on the Y-axis.
There is no "Root node" and no "local_srt node" inside.
By exporting as a model- or animation file from blender I get no error message. But the .model file is only 1,94kb.
It doesn´t matter which model I´ll export. The file size is always the same.

@maneus
Sorry for not replying earlier.
Is the model something you done on your own in Blender from scratch?

The script doesn't rotate or flip your model in any way, so it will look flipped and rotated incorrectly when exporting.
This is what the game_matrix object tries to help you with since it's rotation and scale are cleared automatically when exporting so your mesh ends up in Grimrock space.

You can create a game_matrix object from the Create tab in the Properties Panel in Blender, by default it's configured so that Blender positive X points forward, Blender positive Y points to the left and Blender positive Z points upwards.

If you import for example the Ogre you can see that it's oriented forward in this way, and if you would go ahead and clear the rotation to all zeros and scale it to all ones you can see that it's flat down on it's back in Blender facing positive Z, standing tall in Blender positive Y and mirrored on the X axis, since his hammer is now in his left hand!

This might be the issue with your model nodes comming out wrong.
Why the mesh doesn't contain any data is a bit trickier to guess, is it possible to email me the .blend file so I can look at it?

Good thing you got the animation sorted out!

Also added some information on the game_matrix, handedness and the differences between Blender and Grimrock on the support page,

Thanks for finding the export issues!

Added some tools to work with ground foliage, and skipping hidden objects on export.

Check a rather lengthy rambling post with example
