I didn't cover how to actually perform modelling in this tutorial since it's a bit of a lengthy process to learn, and I wanted to focus more on ROM Manager itself. If using blender as your modelling software I would personally recommend following along with the first three parts in the tutorial series made by Blender Guru linked here-    • Blender Beginner Tutorial (OLD) - Part 1: ...  

The last thing you need to know about Blender before getting started modelling is the extrude feature. Here's a tutorial on that:    • Extrude Overview - Blender Fundamentals  

If you wish to use sketchup as your modelling software instead of Blender then I believe you can get the free version (Sketchup Make 2017) here: https://help.sketchup.com/en/download...

If you want a bit of a primer, Kaze Emanuar uses Sketchup in his tutorials linked here:    • SM64 modding tutorial 01 - Drawing levels ...  

I recommend that same above tutorial series for learning intermediate and advanced ROMHack techniques in general.

Also shoutouts to the Simpleflips discord for answering questions I've had while getting started, including members such as Cheezepin, Felegg, Mr.Comit and Darklink
