This is where the fun begins!

When trying to export a mesh with a dangly mesh I get the following error:

On line 1107 in nvb_node.py:  RuntimeError: Error: Mesh "(insert danglymesh name here)" is outside of main database and cannot be removed from it.

Fix is in the repository (mesh removal made redundant after upgrade).

If I could model a tin can, I would be very excited by this.

I am still moderately excited. Nice tool

Status update: I've done a couple of beta releases (now at beta 4), where I've improved compatibility with MDLedit and added support for editing PTH files. For those interested in baking lightmaps or editing PTH files in KotorBlender, I've listed the necessary steps in the description.

Status update: I'm releasing version 2.0.0, which is the first non-beta version of the updated add-on. I've tested it on quite a few models, doing modelling, texturing, rigging, animation, etc. I think KotorBlender is now on par with KotorMax in terms of functionality: it works equally well for editing (and creating) character and area models, and I'm quite happy with the result.

Here's the excerpt from the release changelog:

• Rewritten handling of materials and lights (Eevee)
• Made materials configurable from Object Properties
• Implemented import & export of LYT files
• Implemented import & export of ASCII PTH files (reone-tools)
• Implemented armature creation (no animations yet)
• Fixed MDLedit compatibility issues
• Removed NWN-specific functionality
• Disabled minimap rendering (until later)
• Code cleanup and refactoring in accordance with Blender and Python code styles

Hey I just wanted to say this is amazing. I've been using blender for awhile and much prefer it to the other main 3D packages, especially Max. Until recently, my workflow has been to import a file into blender 2.79, manually change the textures, so on so on. You can image that this gets pretty annoying real quick. Really excited to see what you can do with it.

When you import a supermodel, some animations on the right arm rotate in a circle. To see what I mean import s_male02 (k1 or k2) and look at animation pausestl. Decompiled with both mdledit and mdlops. This also applies to s_female03.

my novice nature is showing but can this tool be useful for making new characters for a recruitment mod. i have a rough draft in my head that involve Ord Mantell by Redhawke.

That is a known issue - same goes for pre-2.8 version of the add-on. Apparently, it has something to do with keyframe interpolation. Exported animations and imported armatures work OK though, so it's not exactly high on my todo list.

I'm not aware of any hard limitations of KotorBlender, with regards to creating new characters. It may not have as many utilities as NWmax, it lacks tutorials, but you can certainly model, texture and rig new characters using KB.

I am interested in re using one of the female Revan heads(Angelina Jolie one with the red braid) as a base and maybe using other's assets to make a Recruitable character.

The latest version of kotorblender (2.1.0) lacks the folder kotorblender. So it puts the files directly into the plugins folder. 

Also, exporting txi properties throws a traceback error.

[RavinNightBeast 2]

So When I Try To Enable The Add-on It Says It Cannot Be Used With Never Blender Enabled? Can Someone Fill Me In On What I'm Doing Wrong?

[Arson Hole 30]

Is this compatible with Blender 2.93? I'm trying to install it, but all I get is this Traceback Error.

Currently the latest version is improperly packaged.  You can fix this by going to the installation location and putting all of kotorblender's   files in a folder named kotorblender.

Hey, guys. Just wanted to give you a heads up that I'm in the middle of updating the add-on, enabling import and export of binary models based on MDLedit. I noticed that @Arson Hole is using the master version from GitHub. This one is not being properly tested and could be unstable. Please use version 2.1.0 from this site instead, and make sure to put all addon files under a folder named kotorblender, as @Hunters Run just said.

[Arson Hole 30]

Yes, that seems to have done the trick. Thanks a million!

[seedhartha 118]

For those interested, version 3.0 of KotorBlender is out. ASCII MDL / PTH workflow has been dropped in favor of binary importer & exporter. Binary MDL support is mostly on par with MDLops/MDLedit, except it lacks smoothing groups and cannot export saber meshes.

I will fix these as I go. Other plans include streamlining the editing process, e.g. one-click lightmap baking and working with multi-material objects, armature animation export, advanced shader node setups, etc.

Also, an interesting discovery I made about the MDL format - both MDLops and MDLedit expect per-vertex "tangent space" data to have the following layout: Bx By Bz Tx Ty Tz Nx Ny Nz, where B is a bitangent, T is a tangent and N is a normal. However, my experiments show that "tangent space" is actually a transposed TBN matrix, which makes a lot more sense from the engine standpoint: Tx Bx Nx Ty By Ny Tz Bz Nz.

So does this mean that KBlender will be able to import/export the model's original normals directly rather than dealing with MDLEdit/KMax's hacky conversion to/from Max smoothing groups (which is a legacy of MDLOps/NWMax's ASCII format)? Because that is the single biggest problem with the current Max/GMax workflow, causing all sorts of broken shading issues, especially on head models.

Just tested this and yeah - we can import and export original normals, no problem.

So we no longer need to convert a binary model to ASCII—messing it up in the process—in order to modify it, but we still need to use MDLEdit to port it to the other title?

Nope, you just check or uncheck "Export for TSL". No need for MDLedit at all.

[Guest]

Holy crap, this is big. And it works both ways, right? K1 to K2 and K2 to K1? Really appreciated. Truly.

[DarthParametric 3,811]

Note that taking MDLEdit out of the loop doesn't change anything else. You'll still need to rerig most models when switching from one game to the other.
