io_anim_seanim VS Halo-Asset-Blender-Development-Toolset

Originally I extracted models in SEModel format and managed to open them in Blender with this script: https://github.com/dtzxporter/io_model_semodel, but I failed to open SEAnim files (animation files) with this script (https://github.com/SE2Dev/io_anim_seanim), but I get this error:

If you want to import them into blender, use Blender Source Tools, and for animations use this SEAnim Plugin.

Thanks! Initially I was eyeballing it based on ghost and warthog lengths but that quickly proved to be difficult and cumbersome. I got some tips thanks to UneeQ in exporting the BSP (map structure data) from Reclaimer and importing it into Blender using the Halo Asset Blender Development Toolset

First off, I'll assume you're using Blender, so download the Halo Blender Toolset addon (https://github.com/General-101/Halo-Asset-Blender-Development-Toolset) and get it setup in Blender. You will then need to download the Halo Editing Kit from Steam. Once you have all the tags (models, sounds, AI data etc) unzipped, you can use the Blender tools to import models. Use these models and their armatures as a basis to work from.

You can use Blender with the Halo Asset exporter/importer tool to create maps, however it is still in development and Halo 3 is only partially supported. Additionally can visit the Reclaimers Library website for tutorials and other helpful information on the Halo engine (including tutorials on creating maps from scratch)

There's a lot of resources out there now actually! https://c20.reclaimers.net/ is a great hub for all kinds of documentation. fryingpanproductions made a playlist of various tutorials for Halo 3, although it seems like they've been on hiatus. TheChunkierBean also has tutorials, including getting custom assets into Halo 3. Plus the Halo Mods discord is very active and very helpful.

The easiest way to get models is to extract them from the games yourself, since openly sharing them is generally taken down by Microsoft depending on the platform. The current mod tools plus the Halo Blender addon will allow you to pull whatever you'd like straight from MCC. That addon is here: https://github.com/General-101/Halo-Asset-Blender-Development-Toolset Make sure you have at least Blender 3.1.0 if you've already played around with it in the past.

A great resource is The Reclaimers Library website; it's a guide for modding, for beginners, and also covers more advanced topics. It's guide for H1 is the most in-depth, but they also have MCC related guides as well. Since the engines all have very similar "cores", the workflow basics are very similar across games.
