This tutorial will show what you can do to previous . In this tutorial you will learn to add snow effect using material and also create falling snow using Particle Flow. Because this is cartoon style scene, I also create another type of falling snow. Instead of using ordinary snow shape, I will use snowflake image as particle. As you can see later, this scene will be very interesting to put in cartoon fantasy movie like.
Image below show what you can learn from this tutorial
1.First, you need to download scene used in this tutorial here. Use 3ds Max 8 or up to open. If you interested, you can read how to create this scene in Cartoon Landscape tutorial. Image below shows camera view from this scene.
2. First thing to do: Creating snow material. Open Material Editor. There's a Multi/Sub-Object material applied to the scene. Click 'leaves' material. Then click Standard button and change into Composite material. Click OK to keep 'leaves' material as sub-material. Composite is a type of 'layered' material. In case of snow, you can create snow material on top of base material ('leaves' material).
In Composite Basic Parameters, click None button right next to Mat 1. Choose Standard material. This will be our snow material.
In Blinn Basic Parameters, change Diffuse color to white.
3. Scroll down to Maps rollout. We need to specify how much snow covering the base material. Click None button right next to Opacity. In Material/Map Browser window choose Falloff.
4. In Falloff Parameters rollout, switch color between black and white. Use Falloff type=Towards/Away and Falloff Direction=World Z-Axis. In material preview, you should see white color only appear on top.
5. Scroll down and open Output rollout. Activate Clamp and Enable Color Map. Clamp will make material seems brighter. Meanwhile Color Map controls how much snow covering the base material. After you activate Color Map, move leftmost point in graph to -1. Notice the changes in material preview.
6. Click Go to Parent button to go back to Maps rollout. To make more realistic, click None button right next to Bump and choose Smoke. Use Smoke Size=30.
7. Image below shows rendered result so far.
1.In Material Editor, click and drag material to another unused material slot to create its clone. Rename this material. Use any name you want. Apply this material to ground object by dragging this material to ground object in viewport.
Let's adjust some settings. Click 'leaves (Composite)' button. Then, click button right next to Mat 1. Go to Maps rollout. Click Map# (Falloff) button right next to Opacity. Then go to Outout rollout. Move leftmost point in graph to -4.
Click Go To Parent button to go back to Maps rollout. Click Map# (Smoke) button right next to Bump. Use Smoke Size=60. Click Go to Parent again to go back to Maps rollout
2. If you want brighter snow, scroll up to Blinn Basic Parameters rollout. Activate Self Illumination and change color box to grey. Image below show rendered result up to this point.
3. Next, the falling snow. In Command Panel go to Create>Geometry. Choose Particle Systems from drop down list. Click PF Source button. Click and drag in Top viewport to create PF Source icon. Make sure this icon is bigger than objects in scene. Then move this icon above all objects.
4. Open Particle View window (by pressing '6' in keyboard). Select highlighted operator and enter values like shown in image below. You'll get 1000 particle emits from PF Source icon along 100 frame. The particle move at speed between 20 to 40 (30 +/- 10). To make particle visible in viewport as a mesh, Geometry display type is activated
5. Scrub slider and watch falling snow. Do a test render if you want.

, you've created falling snow using Particle Flow. The result should be good enough to render. But in this tutorial, you will get more dramatic rendering by changing particle shape with snowflake image. I also want the snowflakes spinning around vertical axis while falling down.
1.First, create a plane in Front viewport. Use Length=23 and Width=20 with each segments=1
2. Next, we will create material for plane object. Before we continue, right click and save snowflake image below.
Open Material Editor. Select unused material slot. In Shader Basic Parameters activate 2-Sided to make both plane sides textured. In Blinn Basic Parameter, change Diffuse Color to white. Activate Self Illumination and change color box to grey if you want more brighter result.
Now, plane is textured with white color. click small button right next to Opacity. In Material/Map browser choose Bitmap. Use snowflake image. Now, when rendered, black color in snowflake image will make area in plane transparent
3. In Particle View, drag Shape Instance operator from Depot into Event 01. Make sure it replaces Shape 01 (Sphere) operator. In Shape Instance 01 rollout click button under Particle Geometry Object and click plane in viewport. Because plane is too big, use Scale=20% with Variation=10%
4. Next, we are going to add rotation to snowflakes particle. First select Rotation 01 operator, and change Orientation Matrix=World Space and X=90. Scrub slider, you'll see particle going down vertically.
Drag Spin operator from Depot into Event 01. Make sure you place it under Rotation 01 (there's blue line when you successfully insert operator into Event 01). Use Spin Axis=World Space and Z=1.
5. Congrats you've finished Snowy Cartoon Landscape tutorial. Here's sample movie of finished scene. I changed the background with darker image.
