The boat is called RSPM-5.5 ('РШПМ-5.5' for reference), it'sa Russian vessel which is being used both in civilian and military environments.

Vertex count can be drastically reduced by removing the grid in the feet area (it takes 16526 verticies, 21944 quads).

Modeled in Blender 2.83, textured in Substance Painter 2019, rendered in IRay and Unreal Engine 4.

• model consists of 17 objects
• each object uses one material
• texturepack contains 51 png images (284 Mb uncompressed)
• texture size is from 512x512 up to 8192x8192 pixels.

Only the hull uses 8k textures, most of the models use 2k and some of them - 4k.

Each material uses 3 textures:

• Base Color
• Normal Map
• AO-Roughness-Metallic (R-G-B channels)

When using in game engines the AO-Roughness-Metallic image should use linear color (instead of sRGB) to properly represent the material. For example, in Unreal Engine 4 the 'sRGB' checkbox in the image settings should be unchecked.
