How many triangles is the cottonwood tree?

1,690 as proposed. The complexity slider takes it down to a few hundred or up for a hero tree, and the export adds LOD1 and LOD2.

Can I change the height?

Yes, between 10 and 16 m, and the trunk's diameter, taper and lean with it.

Yes. There's no account, no watermark and no limit on downloads.

Can I use it in a commercial game?

Low poly cottonwood tree, built to your size

A low poly cottonwood tree made with PolyMason — 1,690 triangles at 13.0 m, as PolyMason proposes it

Build this cottonwood

Tall riverbank broadleaf, loose and open. As proposed, the cottonwood tree is 1,690 triangles at 13.0 m, with foliage as clumps of leaves. You can take it from 10 to 16 m, and every other control stays within what a cottonwood tree can be.

Cottonwoods grow next to water. It's a tall, loose broadleaf with an open crown of clumps, on a trunk that usually leans a little toward the river. Use it on the American plains, along a creek in a western, beside a prairie homestead or on a flood plain. If your map has a river crossing open country, this is the tree that should line it.

Keep it open. Use a low clump count and a wide spread so the sky shows through the crown, and give the trunk a slight curve and lean. The default greens are mid-toned and slightly warm. The dead version is one of the more useful ones in the set, because dead cottonwoods are common in exactly the places live ones grow. A felled one also looks right on a riverbank, where beavers bring them down.

What you can change

Trunk: height, diameter, taper, sides, lean, curve and gnarl, with bark from the species' colors or any color you pick.
Boughs: count, rings or spiral, where they leave the trunk, angle, length, thickness, curve, and twigs.
Foliage: style, size, spread, complexity (your triangle budget) and two greens.
Export: LOD1 and LOD2, sapling and young versions, dead, stump, felled, logs and billboards.

The export is a zip with OBJ, STL and 3MF. The OBJ uses the shared palette texture and has flat normals in the file. Models are in meters and stand at the origin, and the zip includes whichever levels of detail and other versions you select. The trees page covers the formats, and the OBJ guide covers importing.
