Blender 2.71 - Importer / Exporter (1.4.4)

[Aisuu]

Ha! Iam stupid, it helped many, many thx

[bitcpy]

First draft animation export support, currently doesn't handle skinned objects

It can probably be a bit unstable since I haven't tested it more than exported some gears rotating, moving and scaling.
Tried placing it in-game as well and doing playback on the animation, seemed to work okay.

I'm glad you girls/guys like it and are finding it useful!

Useful? No more .obj! So many annoyances gone...

• model scaled 100x
• normals flipped
• left is right, right is left
• folder full of .mtl files
• materials missing
• no animation

and on and on...this resource has made using Blender enjoyable, really helped beyond getting early access to the models.

@Lark
I tried with the latest 1.3.1 which worked fine. Bringing it into Blender, then exporting and opening it in GMT.
You shouldn't need to bring it into GMT for tangent re-calculations with the latest, it should work just fine in the game.
(I'll double check that in a couple of minutes)

If there's still problem, let me know and I'll see what we can do about it.

@everyone
Thanks for helping each other out

Fantastic! 1.3.1 works perfectly and imports the model without any issues at all! We are not worthy! Thank you! I cannot even imagine the magic you are doing to make this possible. Now I can proceed with the next model I want which will be much easier modifying this alcove. Thanks again, you're the best Bitcpy! (Oh, and I have my fist model ready to go - I'll post it tomorrow at work!)

Sincere Gratitude, -Lark

I just want to say thank you for this awesome script!

[bitcpy]

Sorry for the lack of updates lately, I'll try to push fixes or requests if needed but I will be either really busy or not at home during most of December.
If there's anything you want, keep asking for it and I put it on the list (if it isn't already on it)

Anyways, I updated the script to support armatures as well as rigid objects.
I also added support to import and export animations from and to Legend of Grimrock 1.

This script is excellent and has been immensely helpful so far.

However, I think I've found a couple of bugs.
1. Importing assets/models/env/beach_rock_arch_01.fbx.model and exporting it without changes completely messes up the normals or something similar:

SpoilerShow

Asking Blender to recalculate the normals didn't fix this.

2. Importing assets/models/env/forest_plant_cluster_01.model and exporting it without changes messes up the lighting on the heather (tangents calculated wrong?):

SpoilerShow

Enabling "Export transformed normal map" and/or disabling "Export tangents" just makes the problem worse, as you would expect.

Neither of these were changed by removing doubles.

Updated 1.4 to resolve some issues when importing models with multiple materials on them.

Thanks for finding the model import issue, I had made a small mistake when assigning materials to faces on models with multiple materials on them.
I fixed the issue and uploaded a new version, 1.4.1 should work fine.

For the plant model, I'm a bit unsure what to do, maybe make sure Blender doesn't alter the normals when importing (was supprised that it actually did).
From what I can tell by looking at the model it appears the artists has used smoothed normals on the grass planes through transfered normal attributes.
It's a good trick when working with planes, but I'm not sure Blender can actually do that out of the box since it would require the user to be able to lock the normals or apply vertex-normal maps.
Works really well with short hair on faces as well as you would simply transfer the vertex normals from the mesh below onto the hair planes.

I know I seen some better articles on it but this page from polycount does a fairly good job at describing the effect.
It also shows how to do it in Maya, Modo or Max.

Added so that mesh objects with more than 4 edges (none quads or tris) are automatically selected so user don't have to find them manually when export fails.
Also fixed an issue with mesh objects not being exported if being root nodes.

Great work, bitcpy!
How about register this module official with Blender?
