Lets take [Tiny Trash Panda] as an item that needs a Troxel Contribution.
If the page does not have a Troxel link already, there would be a red exclamation mark next to the Model Viewer and two options would be available:




To Submit Troxel we would need to obtain a Troxel link - this means that we upload a model to the web-based Voxel Editor - Troxel and then export it as a Link that can be shared.

First we need to get the appropriate game files - we can either extract the game files from a Trove game client (installed on PC), or we can downloand already extracted blueprints from the Trovesaurus website one by one.

The game files that we need are the Blueprints - models that are used by the game.

To know which blueprint(s) exactly do we need, we have to visit the page of an item - in this case a Tiny Trash Panda. Click on the Mod Info tab > Blueprint and find a UI model - 2023/allies/egg_trashpanda/c_c_egg_trashpanda_ui - luckily this one is a full model!

On the same Mod Info page we can click a Blueprint button on a desired file and download this UI blueprint, or if we can find a local file by searching the name of the blueprint(s) in the extracted game files.

Items or styles would not have a Mod Info tab, but they always have and Identifier - name of a blueprint they use.

The Troxel does not accept raw Blueprints, so we need to convert the Blueprint to QB files.
Navigate to the Trove/Live folder and create a new folder named qbexport .
The must be a an empty (for now) folder Trove/Live/qbexport , otherwise the next step would not work!

In the Trove/Live folder we need to locate an executable file called devtool_dungeon_blueprint_to_QB.bat .
Then we going to use that. .bat file by dragging the 2023/allies/egg_trashpanda/c_c_egg_trashpanda_ui.blueprint from the Extracted game files onto the bat.
If done right, this will output 5 new files into the Trove/Live/qbexport folder.

If done right, we should have something like this in the qbexport:


Every single .blueprint converted to .qb will create 5 files:

c_c_egg_trashpanda_ui.qb - is a main QB file, this one contains color
c_c_egg_trashpanda_ui_a.qb - is an Alpha material map (_a) for the main QB file, it contains data about transparency of blocks
c_c_egg_trashpanda_ui_s.qb - is a Specular material map (_s) for the main QB file, it contains data about metallic/waxy/etc  blocks
c_c_egg_trashpanda_ui_t.qb - is a Type material map (_t) for the main QB file, it contains data about glowing/glass/etc  blocks
c_c_egg_trashpanda_ui_entities.blueprint - this new blueprints is only used for Dungeon blueprints! it is safe to discard this file, it is not used for Troxel.

Now that we have the files needed, we can go to the https://troxel.js.org/  and upload all the 4 QB files that were created:

Click on Open Model and we should be able to see the model right away. There should also be two new buttons on top, Export and Open: 



For Troxel, we need to use the Export Model As and chose Link (share).
Please use the same settings as on the image below! - Color Pallet Compression and Resize to Bounding Box are checked, everything else is unchecked!



Using those options should give a link - double-click to select it all or click and Ctrl+A . Copy and paste the link into the Submit Troxel field on the same page that we started with - https://trovesaurus.com/collections/pet/egg_trashpanda/troxel :

Once we click the Submit button the Contribution will be added to the Moderation queue - Troveaurus Contribution moderators do their best to check these as soon as they can, but it might take a few days.

Contribution can get Approved - this gives you Contributions Points - good Troxel links are rewarded with 2 points!
Or a Contribution can get Rejected - if this happens, your Contribution was either uploaded to a wrong page, or did not have the right model, or the model was not featuring a full model.
