沙漠绿化（Desert greening） Effect: turn barren desert into oasis Technical analysis: use PaintEffects to generate grass and trees. Making animated animations by shooting particles from objects and matching Texture Rate (texture control launches). Production outline: 1, new desert scenes 2, select the desert, the implementation of Emit form Object:Rate:80000. Speed:0. Make particles from the top of the desert, and extend the animation in a circular manner. 1, give the scene Lambert1 material, add Ramp 2, double-click Ramp: the gradient type is Circular Ramp (round gradient). Reference parameter: Position: 0.55\0.5\0.45 color: Black \ white \ black. 3, time positioning to the first frame: adjust the Ramp parameter for: Position: 0.05\0.025\0, color ditto. And Key respectively At this point, the circle is not at the top, and can be adjusted Place2dTexture (placing a two-dimensional texture) - Offset (offset). Time is set to 100 frames: position: 0.742\0.724\0.689. And Key respectively 4. Connect the Ramp to the Textrue Emission Attributes (texture emitter attribute) in the properties window of the particle emitter, and tick Enalbe Texture Rate In order to save resources, we put it on the back of the desert without emitting particles: 1, double-click Ramp1, check the white color node - Ramp:Interpolation (interpolation type): None. Delete blue. Position: 0.5\0, color: black, white 2, adjust the Ramp2 animation - check the black color nodes Time first frames, Key Time third, 100 frames, position 0.86, Key. 3, open PlaceTexture3 - 2D, Texture, Placement, Attributes - Rotate Frame (angle) - such as 285 4, select particle emitter - Rate Eightieth frames, Key Eighty-first frames, Rate:0, Key (after the particle is controlled to 80 frames, it is not fired.) Use Paint Effects to make grass and grass animation 1, open the Visor 2 Grasses - GrassClump.mel 3. At the origin of the perspective, click At this point, two nodes are generated in Outline: StrokeShapeGrassClump1: control the
