This asset is high poly, its not a raw high poly but a specially and on purposesely dense where needed and loose when its acceptable. also with help of Lods, this asset works pretty smooth and looks still very detailed! (see the Preview video). for detalied vertex counts per mesh and per LOD see this table.
The primary and unique feature of this asset series is its cohesive visual output, resulting from the combined functionality of the mesh and shader. The material is not static or pre-textured; instead, it utilizes a single tileable texture and URP shadergraph (with an included HDRP version) to generate a wide range of procedural looks. Please refer to the provided preview video for a demonstration.
Detailed shader v2.0 capabilities are showcased in this review video, which applies to all Darkline serie assets using the same material.

This pack includes various throne-related mesh modules. You can use these modules individually or combine them to craft magnificent thrones for your heroes or villains.

The potential uses are incredibly diverse
Darkline assets represent alien life forms characterized by black 'drawing' aesthetics, featuring thin/smooth lines or tangled/bold black tentacles. This distinctive visual style is achieved through a highly configurable shader.
The primary and unique feature of this asset series is its cohesive visual output, resulting from the combined functionality of the mesh and shader. The material is not static or pre-textured; instead, it utilizes a single tileable texture and URP shadergraph (with an included HDRP version) to generate a wide range of procedural looks.
