What i did / Steps to reproduce

• Install Quark Mod
• Put Quark jar in resourcepacks folder
• Render The map
• Quark Chests not appearing

Expected result

Quark Chests should be rendered.

Actual result

No blocks are rendered instead of the chests, as if they weren't there

Context

BlueMap Version: 1.7.2-forge-1.18.1
Minecraft Version: 1.18.2
Quark Version: 3.2.357
Forge Version: Forge 40.1.0

The Render

In-Game

Chests in general are Tile-Entities and their Models are defined in Code. For vanilla-chests (and signs etc.), bluemap provides a resource-pack that adds those models in resource-pack format, so BlueMap can read it. For quark-chests and other tile-entities that are added by modes, you can do the same thing.
But, BlueMap will not include those resources for anything other than vanilla Blocks :)

Is there any guide or tips on how to do this?

Basically any Guide on ResourcePacks with custom Block-Models will do most of it ... anything else you can ask about, in our Discord :)
As reference, this is the Resource-Pack that is builtin to BlueMap and provides chests and other tile-entities for vanilla-minecraft: https://github.com/BlueMap-Minecraft/BlueMap/tree/master/BlueMapCore/src/main/resourceExtensions/mc1_18
