SnowFlow是一个3 d Studio Max脚本/插件轻松创造现实的雪!你只选择一个对象和SnowFlow的雪!让雪落在你的3 d对象和场景的点击一个按钮。
你不需要使用VRay SnowFlow,但它可以创建一个自动VRay雪材料。如果你有安装SnowFlow问题,确保你以管理员身份运行设置!
settings
Thickness
This parameter controls the height of fallen snow. Please note that if noise is added, the final snow height can be a bit higher than the value set here. It’s also possible to add more thickness to the final snow mesh with a push modifier.
Noise
Noise controls the amount of turbolences of the snow surface. This makes the snow surface look more natural. You can also add a noise modifier on top of the final snow mesh to get the same effect or use bump/displacement in your material.
Selected faces only
Preselect regions where you want snow to fall on. You can also invert the selection. With this option activated, you must select faces to get a result. This option speeds up the selection process.
Wind / rough surface
This parameter lets more snow fall on vertical parts of an object, like it can be seen on the side of trees. You will get natural looking holes in your snow surface if thickness is small and you don’t adjust particle count.
Transparent = warm
Transparent materials “melt” the snow. Check this option for roof windows or car windows for example where you want to mimic the effect of a warm interior. Note that this can only be used with transparent materials, not textures.
Snowfall reality
Snowfall reality controls parts of the object to be not occluded at all (normal), be occluded by the object itself (high) or be occluded by all objects around the scene (real). Reality set to “real” pushes rendertimes up a lot!
Surface relaxing
Surface relaxing makes a “smoother” surface and makes it look less “blobby”. It has effect on the snow surface even if noise is on. It fills holes in the snow as well. With our “extrusion” method you should keep this parameter relatively low.
Number of particles
This parameter controls the density of the snow surface. You should leave this “autoTuned” most of the time. The “Status & Progress” window will show you the calculated particle count which can be used to finetune this setting.
Polycount This controls the number of polygons created by SnowFlow. Possible selections are:
extremely high, very high, high, medium, low, very low, extremely low. You should start at medium or high and go up or down as you need it. 只有试用版
