This script changes the texture type of a belt buckle m2 to "hardcoded", so you can attach it as a spell in WotLK.
Requires 010 editor.



How it works:
-Put the models you want to modify inside the folder called "Models".
-Run "MassBuckleTextureHardcoder.bat" and wait

It copies the name of your current model and creates a texture path with the same name. If your model is called "Buckle_pinkunicorn" it will create a path called "Item\ObjectComponents\Waist\buckle_pinkunicorn.blp".
This script only works if your model has "BUCKLE_" at the start of its name.

If the model has multiple texture variations, just change its name and a different texture path will be created for that specific file. Example:
Buckle_Leather_RaidMonk_N_01.m2 has 3 textures:
-Buckle_Leather_RaidMonk_N_01.blp
-Buckle_Leather_RaidMonk_N_01Blue.blp
-Buckle_Leather_RaidMonk_N_01Red.blp

If you wish to have all 3 variations, copy the model and change the name of its copies to "Buckle_Leather_RaidMonk_N_01Blue.m2" and "Buckle_Leather_RaidMonk_N_01Red.m2" so the path matches.

To make this script work there must be an entry for 010 editor in environment variables (this allows windows to launch 010 editor through the cmd window, otherwise it won't work):
-Right click on My computer -> properties -> advanced system settings -> environment variables -> Path
-Click edit
-Add your 010 editor directory to the list separated from the rest of the entries by a ";" (Example: ;C:Program Files (x86)10 Editor)

-This goes in the retro-porting forum.
-There are many threads in this forum about models that appear as cubes.
-99% of the time, a cube means that the game can't find the model (aka the path is wrong in the dbcs or the folders you made have wrong names, etc).
-Have you tried swapping the model with another one instead of editing the dbcs to check if the model really works?
-You are giving almost not information or screenshots of your model, or your dbcs, or the converter you used.

Note: Inico died on the way back to his home planet.

If you still don't know what is wrong, post rather screenshots of your DBCs.

He already made a post about this in the retroporting forum with screenshots of his dbcs.

I don't get it. You are trying to convert a zebra model from legion that is already in the wotlk client. Why?
Posting those images is not usefull at all. Why don't you post images of the convertion process instead? We can't help you with the non-specific information you are providing. The converters work perfectly, you are doing something wrong.

The person from your second image just swapped the Flying Cloud model with a sword and rotated/scaled it in Blender. It's a basic model edit.
Just use Blender and M2mod (there is one for WotLK and another one for WoD).
Since you are not specific at all, I would think that you are trying to achieve the "cloud" effect under the sword, right? Well, that's inside the flying cloud mount model. You don't need to edit any DBC. You can clone the cloud particles to your sword model with Particle Cloner or just convert the cloud mount model with m2mod, edit it with blender and add the sword geometry.
By the way, this goes in the modeling forum.

How can  i open the animation model ? And where do i find it ?
Can you help me cause i'm still a beginner

What you are trying to achieve is not for beginners. Once you know how models work, it's just common sense.
There is no such thing as an animation model as in Unreal Engine. Animations are stored inside the character M2 file, however some of them (mainly emotes) are separated into .anim files, but you have to edit the M2 file to swap the animations. You must rename those files only if the animation has a .anim file attached to it, but that's just the easiest part.
