    تفضل أخي الكريم ... هذا توتوريال لنمذجة و خامات شلال
    Creating Waterfall by Ronel K. Pabico

    I want to share my work on how to create a Waterfall from 3ds Max Particle System. To start with, set units to meters, and renderer to default scanline renderer. You can download my raw model for the building from here. (3dmax 8 and above). Raw image should look like the image below.

    Modeling the Accessories

    To model the riverbed

    Create a plain length = 20m, width 25m, segments = 8 x 8
    Applied with Noise Modifier: scale=0, strength x=1.7, y=1.5, z=.25
    Positioned it and levelled with the building bottom


    To model the water surface

    Create a plain length = 20m, width 16m, segments = 8 x 8
    Applied with Ripple Modifier: amplitude 1=.06m, amplitude 2=.15m
    Wave Length=1.0m, phase=.1, decay=.001
    Positioned it about .5m below the ground floor of the building.


    To model the main Rocks

    Create a box, length=12m, width=2, height=8m segments 40 x 20 x20
    Apply with Noise Modifier to make it rough and bumpy.
    Then apply with turbosmooth modifier to smoothen the surface
    Position the bottom just level with the riverbed.
    Accessorized the scene with small rocks, same procedure with the main rocks but with a smaller scale. The raw scene model will now look like on the figure below

    To model the water fall. From the Create Panel, select Geometry and choose Particle Systems. On object type choose PArray. Then drag anywhere on the screen to create a PArray Icon. Size of the icon doesn’t matter; as long as you can see then it would be fine. Or go to Tab Menu, choose Create then browsing down, choose Particles, there you can also find PArray

    To model the water source. Go to Create Panel then Standard Primitives and on Object Type rollout choose box. On your top viewport, create a box about the width of the main rocks say length=8m, width=0.1, depth=0.2m. Positioned it on top of the main rock or where the waterfall is located. Named it as source box. See figure below

    Linking the source box to the particles. Select PArray Icon, go to modify, under Basic Parameters go down on Object Base Emitter and press the box Pick Object then select the source box. Now click anywhere on the screen to turn off the selection

    Now go to your perspective viewport and zoom a bit on the source box facing where the water will fall. Select the source box, right click and choose convert to poly. Then on modifying panel select polygon, then select the front of the source box. Turn off the selection, by clicking on the gray box aligned with the word - Editable Poly, this will just turn off the highlighted portion but still the selection is active.

    Select again the PArray Icon, Go to modify and underneath the Particle Formation tick the box of Use Selected Sub-objects. This means that water will come out only on the face of the source box you selected.

    Now make the four viewport viewable, zoom in to the source box and make some initial testing, move your time slider to 20 or 30 and see what happens. The particles emit at horizontal direction

    Fine tuning the particles for initial settings, from the Viewport Display of PArray select Ticks, and for the Percentage of the Particles make 100%.

    On the Particle Generation click on Use Rate=100, for the speed= .2 meter, variation 50, divergence 20

    Speed -The velocity of the particle at birth, along the normal, in units travelled per frame.
    Variation - Applies a percentage of variation to the speed of emission for each particle.
    Divergence - Applies an angular degree of variation by which each particle's velocity can vary from the emitter normal.

    On Particle Timing, emit start at 0, stop at 100, Display until 100. Life at 100 and variation at 25. On Particle size, put .06m, variation size about 10. This means that drops of water is about 60mm so it is viewable on my camera. See illustrated image for the initial settings.

    Now adjust the time slider on about frame 40. As you can see in the image below, the Particles now have some development

    Redirecting the Particles to fall downwards. For the meantime, drag the time slider back to frame 0, then maximized your top viewport. From the Create Panel, select space warp (wave symbol), then on Object Type select Forces, then Gravity or go to tab menu, select create - space warps-forces then gravity. Or go to Tab Panel and choose Create Menu, on the pull down menu items select SpaceWarps - Forces - then Gravity.

    Drag anywhere from the screen to make a gravity icon. On top it’s a square icon with x on center and on elevation it’s a line with an arrow. The arrow indicates the direction of the force. Size and location doesn’t matter as long as you see it.

    Click on Bind to Space Warp icon, then click on Gravity Icon (the mouse pointer will change into small box with wavy diagonal lines) and drag them it to the Particles Icon. The particles will be highlighted in a second which means the binding is okay. Then go to modify panel, on parameters, adjust strength = .04

    Strength - Increasing Strength increases the effect of gravity; that is, how objects move in relation to the Gravity icon's direction arrow. Strength less than 0.0 create negative gravity, which repels particles moving in the same direction and attracts particles moving in the opposite direction. When Strength is set to 0.0, the Gravity space warp has no effect.

    Decay - When Decay is set to 0.0, the Gravity space warp has the same strength throughout world space. Increasing the Decay value causes gravity strength to diminish as distance increases from the position of the gravity warp object. Default=0.0.


    Now play on your time slider at frame 25 and see the flow of the particles. We now corrected the direction and orientation of the flow of the particles. But as you can see, it goes down directly down at the bottom, instead at the water surface. We will now correct this in the next step.

    Move back the time slider to 0, right click gravity icon and select hide selection. Go to Create Panel, and select Space warps browse down the selection and select Deflectors and from the list click deflector. On top viewport drag on the location of the waterfalls, and assume the size of your water surface. Then on left or front view position it or aligned with water surface.

    Make the top view active, go to main toolbar and select bind to space warp icon, then select deflector icon and wait until the icon change then drag it to the Particle Icon. Then go to modifying panel and on parameters and adjust the bounce. For this I make it .25, and variation to 40.

    Bounce - Controls the speed at which particles bounce off the deflector. At a setting of 1.0, particles bounce off the deflector at the same speed they struck it. At 0.0, particles do not bounce at all. At values between 0.0 and 1.0, particles bounce off the deflector at a speed reduced from their initial speed. At values greater than 1.0, particles bounce off the deflector at a speed greater than their initial speed. Default=1.0.

    Variation - The amount by which each particle can vary from the Bounce setting.

    Now the setup is almost complete, play with your time slider and sees the reaction of the particles. Move the time slider to 35. See image below.

    Applied the materials to the particles. Fine tune the particles. Position the time slider at frame 40. Click PArray Particles, go to modify and from Particle generation adjust Use rate to 600. Then right click on the Particles, activate object properties, and enable Motion Blur, select image then click ok.



    Unhide and unfreeze all objects, click on camera, go to modify and activate Render Effect Pass with a total pass of 2. And finally press F10; go to Renderer, Object Motion Blur click apply. Frame duration to .5 samples to 10, duration subdivision to 10. Select source box, right click and choose object properties and uncheck Renderable.
