AlphaTrees 2.1.3 Pro
Alpha trees pro 2.3.3
Blender中快速渲染大片森林的插件。
传统的树模型通常有数百万个多边形和多个复杂材质，因此渲染速度非常慢。它们还会降低视口的速度，并在工作时增加视觉噪音。
它们也会占用大量内存，拥有所有这些多边形和纹理的另一个问题是，它们可能会增加GPU的内存限制并使其过载，导致必须在CPU上进行渲染，这通常要慢5到10倍。
使用Alpha树以100倍的速度渲染树数
AlphaTree使用平面树卡来加快渲染速度并降低内存使用率。每个树卡只有4个顶点，与通常在3D树模型中找到的数百万个顶点相比，性能显著提高。
就像3D树一样逼真
AlphaTree使用先进的材质，可以对光线和半透明做出反应。这意味着它们仍然可以看起来是3D的，而不需要额外的几何图形。
由于树木是二维的，你可能会认为当相机从侧面观察它们时，它们会消失。然而，它们会自动面向活动摄影机，给人一种令人信服的错觉，即它们是3D的
只需单击几下，即可分散并渲染数百万棵树
该插件有一个强大的散射系统，建立在几何体节点上，可以让你轻松地在树上覆盖地形。您可以完全控制密度、比例、旋转、随机性，甚至风动画
程序分配
您可以使用功能强大的权重层系统按程序控制树木的密度和比例，该系统允许您基于坡度、高度或与摄影机的距离等因素影响权重贴图。
如果你想要更多的分散和分发功能，你可以使用分散5插件轻松地插件，并获得强大的功能，如集群，手动分发和更多！
有28个现成的生物群落
无需担心树木的自然选择，通过“散布”，你只需找到一个你喜欢的生物群落，只需单击一下，就可以自动为你散布一片令人信服的森林。
摄影机视野之外的树会自动剔除，以减少内存和渲染时间。如果它们仍然使用太多内存，您可以选择从高（2k）到低（256p）的质量，从而进一步减少64倍的内存使用。
Render Massive Forests, Fast
Tired of 50 hour render times for nature scenes?
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.
Use Alpha Trees to render 10x the no. of trees 10x as fast
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
Scatter and render millions of trees with just a few clicks
*only available in pro version
Complete control
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.
Now with Scatter 5 integration
*only available in pro version
Extremely powerful
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.
Optimised to the core
Minimum memory, maximum
speed
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.
But wait, there's more!
Versatile material
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!
