installation

Just run the installer of SnowFlowPro. You will find the SnowFlowPro object in the "Create panel". There you select "Geometry" and choose "SnowFlowPro" from the dropdown list. The SnowFlowMtl and VRaySnowFlowMtl are listed in the material editor.

If you installed the demo version you should first uninstall it by deleting the file "SnowFlow.dlo" from "[3DStudioMax]\plugins" to avoid problems.

SnowFlow 1.9 gets also installed. You can run SnowFlow 1.9 as a macroscript from your toolbar or directly through SnowFlow.mse from "[3DStudioMax]\scripts\48design\SnowFlow".

licences

After purchasing the plugin, you will have to activate it on the machine you want to use it on. For network rendering you just need to install SnowFlowPro on each render client. You do not need to activate it on your renderfarm.

Settings

Below you find all the settings of SnowFlowPro with a short description.
For the OLD SnowFlow 1.9 (included for nostalgic reasons) take a look inside the SnowFlow Quick Guide which includes detailed explanations as well as Tips & Tricks for workflow optimisation.

Setting 'snow covered objects' Snow Covered Objects
This is where you pick the objects that should be covered with snow. The first button enables you to pick a single object. When selected you can press <h> key on your keyboard to open a list for selecting multiple objects. The second button deletes a selection from the list of snow covered objects.

Button 'let it snow' Let it snow
By clicking on that button you start the snow process. All objects listed in the "Snow Covered Objects" box will have a snow coat after the computation.

Setting 'grid width, grid height' grid width, grid height (Basic Parameters)
You define your snow mesh dimensions via width and height. Dependent on your scene the resulting mesh will have about widht*height*2 triangles. Higher values result in a more accurate snow mesh covering the objects but also the amout of triangles rises dramatically. So be careful with your choice to find a good trade-off between accuracy and amout of triangles. You can also add an optimize modifier afterwards to shrink polygon count.

Setting 'quad grid' quad grid (Basic Parameters)
If you select quad grid the mesh's surface rectangles will be quadratic when viewed from the top of the scene, as shown in the example on the left. This ensures an equal sampling distance in x- and y-direction of your scene.

Setting 'surface roughness' surface roughness (Basic Parameters)
This parameter lets you control the surface slickness of all snow covered objects at once. With a value near 0.0 only faces parallel to the ground will be coated with snow (this is a very slick surface). With higher values snow will also stay on inclined faces. Thus the faces are more "rough" and even strong inclined faces can hold snow.

Setting 'gap height' gap height (Basic Parameters)
This parameter concerns the height difference of two adajacent (snow) areas at their common edge. On one hand these two areas are considered to be two seperate areas with a smooth snow bridge at their edge in common, if their height difference is greater than the gap height parameter's value. On the other hand these areas are seen as one single area with probably a sharper snow bridge, if their height difference is less than the choosen gap height.

Setting 'thickness' thickness (Basic Parameters)
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.

Setting 'consistency' consistency (Basic Parameters)
The consistency influences the snow curve on an edge. Wet snow (value > 0.7) builds a rather sharp curvature whereas powdery snow (value < 0.3) has a significant soft curvature.

Setting 'noise' noise (Basic Parameters)
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 a similar effect or use bump/displacement in your material.

Setting 'shell' shell (Basic Parameters)
With shell checked, the snow mesh will be closed at the bottom side and form a closed solid mesh. This is useful for SSS effects for example. Attention: this doubles the triangles of the snow mesh!

Setting 'blend outer edges' blend outer edges (Advanced Parameters)
Snow edges on an elevated snow area (termed as outer edges) show slight artifacts when covered with less snow as shown in the example on the left. If these artifacts occur then they can be moderated with this parameter.

Setting 'blend inner edges' blend inner edges (Advanced Parameters)
Snow edges on a lowered snow area (termed as inner edges) show slight artifacts when covered with less snow as shown in the example on the left. If these artifacts occur then they can be moderated with this parameter.

Setting 'explode objects to elements' explode objects to elements (Advanced Parameters)
SnowFlowPro temporarily seperates all object parts/elements for calculation purposes. During the computation of the snow mesh a teapot would be split in its seperate parts: the body, the handle, and its spout.

Setting 'collapse self-intersections' collapse self-intersections (Advanced Parameters)
Self-intersections inside an object are collapsed. Change this parameter if you experience problems as shown in the image.

Setting 'direct visible faces only' direct visible faces only (Advanced Parameters)
This can be compared to parallel light from above. Only face that would be directly lit will be covered with snow. Overshadowed faces will be left plain.

Setting 'surface relaxing' surface relaxing (Advanced Parameters)
Surface relaxing makes a "smoother" surface. It has effect on the snow surface even if noise is on.

Tips, Tricks & Pitfalls

The following tips, tricks and pitfalls should help you to find ways around unwanted artefacts generated by SnowFlowPro. These artefacts arise because of calculation problems where no workaround could be found but can be bypassed by parameter settings.

Tips and Tricks 'needle-like artifacts' needle-like artifacts
If you experience a problem like shown in the image on the left try to lower the "surface roughness" parameter.

Tips and Tricks 'wrinkle artifacts' wrinkle artifacts
These artifacts are depicted in the image on the left. To avoid or moderate wrinkles try to increase the "consistency" and "surf. relaxing" parameter as shown in the example on the left. These wrinkles arise because of the sampling technique used to calculate the snow heights.

Tips and Tricks 'hole artifacts' hole artifacts
Avoid too steep faces as shown on the left. They will lead to ugly holes in the blanket of snow. The problem arises because these faces can not hold snow. As a result they are left out during snow triangulation. We already integrated a fix to moderate the appearance of these artifacts but they still can occur. The ring on the left has been slightly rotated about 5° so the side faces very steep and therefore can not hold snow (see red circle). For steep faces (seen along the negative z-axis) keep the following in mind: 0° to 84° and >90° is ok but 85° to 90° will cause hole artifacts.

Tips and Tricks 'choose adequate grid size' choose adequate grid size
Always keep in mind that a coarse grid size absorbs detailed structures and an extreme fine grid size leads to a huge amount of triangles (> 50 million). On the first image a very coarse grid is used for the snow mesh. Most of the details of the locomotive are absorbed. The result of an appropriate gird size is shown in the bottom image. Details can still be seen. Hint: you should start at a coarse grid size and refine it step by step until you have satisfying result.
If you want to shrink polygon count after calculations you can always add an optimize or ProOptimizer modifier on top of your stack. This will ensure that mostly plain parts of your snow mesh are left fairly rough triangulated but parts that need more tesselations will keep details.

Tips and Tricks 'split your scene to sub-scenes if necessary' split your scene to sub-scenes if necessary
If you have a large ground with detailed objects on it, it's better to separate the ground from the objects: one SnowFlowPro for each object set. The ground only needs a few triangles for good snow results but the objects need a finer snow grid. In the example on the left a grid of 400x400 is used for both teapot and plane with one SnowFlowPro. On the right side the scene is split. For the plane a snow grid size of 50x50 is used and for the teapot a grid size of 100x100. As you see the triangle amount dramatically decreases while the teapot's snow mesh is notably more detailed.

Tips and Tricks 'choose an appropriate thickness' choose an appropriate thickness
Snowbound objects are only detectable by SnowFlowPro if these objects are fully connected or intersect themself. In the example shown box 1 and box 2 stick together whereas box 3 has a levitating part. The upper left image shows the object setup. The upper right image shows the objects with a moderate thickness. In the two images below the thickness is increased. On the left the snowbound objects look plausible whereas the snow looks weird on the right side (red circle).
