We are sharing a resource shared some time ago, but always useful for creating 3d forests in your scenes shared by Midge Sinnaeve, on mantissa.xyz, he has released five free models of fir trees in FBX and Blender format, with 2,048 x 3,072px PBR textures: diffuse, normal, specular, roughness and displacement maps.
15 free hi-res tree models s are available in packs: one of ten ‘generic’ trees (that is, not modeled on any actual species) for quickly populating scenes, and other packs with models of Cherry, Japanese maple, Birch Trees.
10 tall fir trees collection, photo scanned bark texture
This is a collection of 10 tall fir trees with a 9K photo scanned 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.
The pack also includes 8 bonus models that don’t have UV’s on the needles but might prove useful nonetheless.
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 into your scene.
