This is a collection of 10 tall fir trees with a 9K photoscanned bark texture. The pack consists of 10 models each roughly 2-3 million polygons as the individual needles are models. An additional 5 models of dead trees are included as well.
You can down a sample version with lower resolution textures here: https://mantissa.xyz/resources
The pack also includes 8 bonus models that don't have UV's on the needles but might prove useful nonetheless.
If you like them, consider purchasing this pack as a way to support the work.
Textures included are Diffuse, Specular, Roughness, Normal and Displacement for the bark, and a small texture for the needles. There is one master .blend file meant to be used as an external library, so you can easily import them in to your scene.
The individual models are also included as FBX if you prefer to set up the materials yourself.
The render shown is a demo scene that's included with the download.
Please note that these models are made for Cycles. Eevee doesn't handle many high resolution models well, I would advise against using these models with that intention.
