3D tree models are slow
Traditional tree models often have millions of polygons, and multiple complex materials, making them very slow to render. They also slow down the viewport and add to visual noise while working.
They also use a lot of memory
Another problem with having all of those polygons and textures is that they can add up and overload the memory limits of your GPU, resulting in having to render on the CPU, which is often 5 to 10x slower.
Billboards are much faster
Alpha Trees uses flat tree cards to speed up rendering and lower memory usage. Each tree card only has 4 vertices, drastically increasing performance when compared to the millions usually found in 3D tree models.
Just as realistic as 3D trees
The tree cards use an advanced material that allows them to react to lighting and translucency.
This means that they can still look 3D, without needing the extra geometry.
Always best side forward
Since the trees are 2D, you might think that when the camera views them from the side that they would disappear. However, they automatically face towards the active camera, giving the convincing illusion that they are 3D
The addon has a powerful scattering system built on geometry nodes that lets you cover a terrain in trees with ease. You get full control over density, scale, rotation, randomness, and even wind animation
With procedural distribution
You can control the density and scale of trees procedurally using the powerful weight layers system, which lets you affect a weight map based on factors such as slope, height, or distance from the camera.
If you want even more scattering and distribution features, you can use the addon easily with the Scatter 5 addon, and get access to powerful features such as clumping, manual distribution and much more!
With 28 ready made biomes
No need to worry about getting a natural selection of trees, with Scatter you can simply find a biome you like and with a single click have a convincing forest automatically scattered for you.
Minimum memory, maximum
Trees that are outside the camera's field of view are automatically culled to reduce memory and render times. If they still use too much memory, you can choose the quality from high (2k) to low (256p), reducing memory usage by a further 64x.
Made for any hardware
All promotional images for Alpha Trees were rendered on a 4-year-old laptop GPU with the minimum recommended VRAM for cycles (2GB). Rendering these images on the same hardware using 3D tree models would simply not be possible.
Each tree can be customised using the material, allowing you to change everything from color, randomness and translucency all the way to number of dead leaves, the color of the trunk and the amount of snow lying on it.
~150 builtin trees
The Addon comes with a rich library of premade trees, including ~70 deciduous trees, ~50 coniferous trees, and ~20 small trees and shrubs. You can also easily search through the library by name, species, size, or tags to find exactly what you want quickly.
Easily create your own
You can convert almost any 3D tree to an Alpha Tree in just a few steps! The addon will automatically render out color, normal, shadow and mask passes, and then combines them into an Alpha Tree that you can use like any other!
