Grimrock

Hey there!
im new to the modding community and i wanted to start small with some simple items for the editor (for example, low level weapons for longer dungeons-better weapons-unique weapons, more food variety, more armors and some bone piles nothing etc) now keep im mind i have never used programs like blender or anything else for that matter so my results will be interesting.

Couple of pointers to help you get started. First you will need the asset pack, it has the 3d models, icons and scripts that you will need. Everything will go in "your_dungeon/mod_assets folder. using the items.lua or objects.lua in the scripts folder there, you can "clone" existing items or objects from the asset folder. (Items being things you can carry, objects are more like decorations.) just copy/paste using a text editor from the asset pack. You can then change the propertiesin that text file however you like (it's pretty straightforward, what model to use, what icon to use, etc. . .) If you make your own model, you will need to save it as an .obj (blender) and import it to GMT that you can get from here (Grimrock Modeling Toolkit). that will give u the ability to move it how you need to, and assign textures. Most importantly, it will allow you to save as .model (grimrock format) hope this helps you out

Best thing to do is to briefly read the Modding docs, Asset Definition Reference, especially.
Then download the Asset Pack like Msyblade mentioned. Save it somewhere outside of your dungeon folder so it doesn't inflate the size of your mod.
Then read through the assets in the pack, and compare it to what you've read in the Asset Definition Reference.
