Stealthinator31

Im making a mod and im trying to change the model of a stimpack because i don't want a stimpack and i have a custom model, but whenever i change the model it crashes the Creation Kit, this is really frustrating and i can't find anything about this

Im making my first mod and there is a consumable in it that i want to increase the FOV of the player by 18.5% because i want the player to feel faster then they are because the consumable increases their movement speed but the amount i want feels slow so i want it to feel faster while still keeping the same speed, How would i do this?

Im making my first mod and im having issues with textures not appearing on an .obj file in outfit studio because i can't add a .mtl, someone told me to use a .bgsm to add the textures but i don't know how to convert the .mtl, if anyone could let me know how to do this that would be great

So im trying to make a mod that basically adds Octanes Stim from Apex legends into Fallout 4, i tested it by adding a new effect to stimpacks and set the magnitude to 30 which seemed to work, But i want to add a new item entirely and i want the Model and Animation to look like its from Apex (The actual stim model duh and the animation of putting it in, while its in with the hand thing he does and then pulling it out) I also want to have the FOV increase while its active like in the game (not sure how much it increases im still looking into that) how would i accomplish this? any help appreciated
