Requires Unity 5.6.2 or higher.
Pack support unity:
- Unity 5.6
- Unity 2017
- Unity 2018
- Unity 2018 LW SRP
- Unity 2018 HD SRP
This pack contain 8 PBR mountain fir trees in 47 prefabs. (26 standard prefabs + 21 vegetation studio prefabs). Trees could be placed in forest (special forest tree versions) or as standalone. All trees work perfectly with unity terrain and Vegetation Studio system (separated prepared prefabs). They are carefuly optimised and created from scanned data. Trees have low overdraw, drawcall usage and are very cheap in render. All trees contain very advanced wind shading. Trees could be overlayed dynamicly by snow, this feature also give you ability to adjust snow amount on trees at static scenes.
We prepared 3 kind of trees:
- normal : where 4 from 8 trees have 2 bark materials for cool blend at bark
- cheap where all trees have 1 bark material (less drawcalls) and all trees could use the same leaves and bark. This means that 8 types of trees will be batched together (very low drawcalls for whole forest).
- normal with snow
- cheap with snow
Please download version for 2017 on unity 2017+ and 5.6 at unity 5.6. Shaders for trees are compiled separately for both engine versions (unity changes). Set linear render or adjust (decrease colors) for gamma.
All cheaper version of trees could be batched togerther so drawcall usage will be decreased dramaticly even with 8 types of trees at the scene.
In our pack you will find 4 aspects:
1) Different stages of trees like:
- plant
- small
- medium
- 2 big standalone
- 2 forest trees (less tri and shadows on the ground)
- dead tree
2) Group of textures for trees (compressed in Albedo/Alpha; Normal; Metallic/AO/Smoothness) for cheaper gpu render and less memory usage:
- snow set (5 textures)
- 7 bark sets (24 textures)
- leaves (3 textures)
- 8 cross texture sets (24 textures)
3) Shaders:
- All shaders support vegetation studio instanced indirect out of the box
- 2 Cross shaders (no snow, snow),
- 4 Bark shaders (metalic, metalic snow, specular, specular snow)
- 4 leaves shader (metalic, metalic snow, specular, specular snow)
- snow is dynamic so tree could be covered at runtime.
- dynamic snow realtime update at vegetation studio need additional script to acces into VS coppied materials..
- you could adjust snow amount and snow distribution by 2 values (snow amount, snow treshold).
4) Advanced and cheap in render wind shading:
- new wind system which generate epic result available from 1.5.v of this pack.
- wind will be shared between our all assets
- wind works 1:1 like in HD SRP
Fir Trees LOD'S and triangles:
Plant:
750/340/ 8 (cross)
Small:
3900/1800/900/400/ 8 (cross)
Medium:
10000/4100/2100/1000/8 (cross)
Big Standalone:
16000/9000/5000/1300/8 (cross)
Forest:
7000/2800/1400/400/8 (cross)
All textures are high quality from scanned data. Resolution is from 1024x2048 up to 4096x4096. They look very good also at lower resolution setup. You could match them to your goals. As trees have shared materials and textures drawcall and gpu usage is very low so it's good to hold even high resolution textures because they don't cost much.
Note: We advice to use forest trees in forest to get better light and performance result and standalone versions on forest border and sometimes inside forest. This setup will give best visual and performance result.
Note2: In our screens we used our: Advanced Foliage Pack (grass and ground textures), Advanced Rock Pack (rocks and rock shader), CTS (terrain shading) and third party assets: Enviro (sky and light), Vegetation Studio ( foliage system)
Note3: LOD0 could be used in archviz, even with LP for such project type they look very realistic. Scanned data and sculpted details gives realistic looking.
Note 4: Demo from forest video is available under this LINK
To open our demo you need::
- River Auto Material;
- Vegetation Studio;
- Advanced Rock Pack;
- Advanced Foliage Pack;
- Mountain Trees - Dynamic Nature;
- CTS Complete Terrain Shader;
Link to all assets are below.
IMPORTANT:
Pack contain ported wind from Unity 2018 HD SRP into lower unity versions and LW SRP this means that asset uses: NMWind.cginc ,NMWindNoShiver.cginc ,NMWind.hlsl, NMWindNoShiver.hlsl, NM_Wind.cs, ShaderWindSettings.cs, 3DNoise.psd, GustNoise.psd under Unity Companion License see Third-Party Notices.txt file in package for details.
需要Unity 5.6.2或更高版本。
包支持统一:
- Unity 5.6
- Unity 2017
- Unity 2018
- Unity 2018 LW SRP
- Unity 2018 HD SRP
这个包包含8 PBR山冷杉树在47预制。(26个标准预制件+ 21个植被工作室预制件)。树可以放置在森林中(特殊的森林树版本)或作为独立的。所有的树木与统一的地形和植被工作室系统(分开准备的预制件)完美配合。它们是根据扫描的数据精心优化和创建的。树有低透支，drawcall的使用和非常便宜的渲染。所有的树都有非常先进的遮阳。树木可以被雪动态地覆盖，这个功能也让你能够在静态场景中调整树木上的雪量。
我们准备了3种树:
-正常:8棵树中有4棵树有2种树皮材料用于树皮的冷却混合
-便宜的地方，所有的树都有一种树皮材料(更少的drawcalls)，所有的树可以使用相同的叶子和树皮。这意味着8种类型的树木将被批处理在一起(对于整个森林来说非常低)。
-正常有雪
-有雪便宜
请在unity 2017+和unity 5.6上下载2017版本。树的着色器在两个引擎版本中分别编译(unity更改)。为gamma设置线性渲染或调整(减少颜色)。
所有便宜版本的树都可以批处理在一起，这样即使场景中有8种树，drawcall的使用也会大大减少。
在我们的包中，你会发现4个方面:
1)树木的不同阶段，如:
——植物
——小
——媒介
- 2大单机
- 2棵森林树木(减少地面上的三角和阴影)
-枯树
2)树木纹理组(在反照率/Alpha中压缩);正常的;金属/AO/平滑)更便宜的gpu渲染和更少的内存使用:
-雪布景(5个纹理)
- 7套树皮(24种纹理)
-叶子(3种纹理)
- 8个交叉纹理集(24个纹理)
3)着色器:
-所有着色器支持植被工作室实例化间接开箱即用
- 2交叉着色(无雪，雪)，
- 4个树皮着色器(金属，金属雪，高光，高光雪)
- 4叶材质(金属，金属雪，高光，高光雪)
雪是动态的，所以树可以在运行时被覆盖。
在植被工作室动态雪的实时更新需要额外的脚本来访问VS复制的材料。
-你可以调整雪量和雪分布2个值(雪量，雪阈值)。
4)先进和廉价的渲染风遮阳:
-新的风系统，产生史诗般的结果从1.5开始可用。这个包的V。
-风力将由我们所有的资产共享
-风是1:1的，就像HD SRP一样
冷杉树和三角形:
植物:
750/340/ 8(交叉)
小:
3900/1800/900/400/ 8(交叉)
介质:
10000/4100/2100/1000/8(交叉)
大独立:
16000/9000/5000/1300/8(交叉)
森林:
7000/2800/1400/400/8(交叉)
所有纹理都是高质量的扫描数据。分辨率从1024x2048到4096x4096。它们在低分辨率设置下看起来也很好。你可以将它们与你的目标相匹配。因为树有共享的材质和纹理drawcall, gpu的使用率非常低，所以保持高分辨率的纹理是很好的，因为它们不需要花费太多。
注意:我们建议在森林中使用树木以获得更好的光照和性能结果，在森林边界和有时在森林内使用独立版本。这种设置将提供最佳的视觉效果和性能结果。
注2:在我们的屏幕中，我们使用了:高级树叶包(草和地面纹理)，高级岩石包(岩石和岩石着色器)，CTS(地形阴影)和第三方资产:环境(天空和光线)，植被工作室(树叶系统)
注3 OD0可以在archviz中使用，即使对于这样的项目类型使用LP，它们看起来也非常逼真。扫描的数据和雕刻的细节给现实的看。
注4:从森林视频演示可在此链接
要打开我们的演示，您需要:
- River Auto Material;
-植被工作室;
-先进的岩石包;
-高级树叶包;
-山间树木-动态的自然;
- CTS完整地形着色器;
链接到所有资产如下。
重要的是:
