Create a Game Ready Fire Extinguisher with 3D Studio Max: Part 1

In this tutorial you'll learn how to create a shower of sparks using 3ds Max and Particle Flow.

1. Particle Flow Setup

Step 1

First, create a Particle Flowsystem. Go to Create > ParticleSystems > PF Source and draw out a PFSource icon in the Perspective viewport, and position it a bit above the groundgrid.

Step 2

Nowpress 6 (or click on Particle View) to open the Particle View window.

Step 2

With the BirthOperator selected, enter a value of 0 for Emit Start, and 100 for Emit Stop and set the Amount to 2000. This means theparticles will start from frame 0and stop at frame 100 and the totalamount of the particles/ frame will be 2000.You can edit the values as per your needs.

Step 4

Now with the Speedoperator selected, set the values for Speedto 1500, Variation to 20 and Divergence to 50.

Step 5

Withthe Display operator selected, turnthe Type to Geometry. Now the particleswill look like cubes based on the Shapeoperator settings.

Step 6

Thecubic shape of the particles looks quite big. So with the Shape operator selected, decrease the Size value to something quite low.

Step 7

Now go to Space Warps> Forces > Gravity and drag a Gravityicon out in the Perspective viewport.

Step 8

Back in the Particle View window, add a Forceoperator into the event by dragging it out of the Depot and dropping it between the Rotation and Shape operators. With the Forceoperator selected, click on Add and select the Gravity icon from theviewport. This will add the Gravity into theForce Space Warps list.

Step 9

The spark particles should collide with the ground and bounce abit before dying, so we need to add a deflector into the scene. So go to Space Warps > Deflectors > Deflectorand drag out a Deflector icon in thePerspective viewport.

Step 10

Add a Collisionoperator into the event. With the Collisionoperator selected, click on Add andthen select the Deflector icon inthe viewport. This adds the Deflectorinto the Deflectors list.

Step 11

You can see now that the particles collide with the deflector andbounce continuously. We don't want the particles to bounce continuously afterthe collision. Practically, they should bounce only twice and then adhere to theground. So turn on Collide Multiple Times with a value of 2. We want the particles to stop after two collisions, so select Stop for the Speed.

Step 12

The particles are still bouncing a lot. So with the Deflector icon selected, decrease the Bounce value to something like 0.05 and change the rest of the parameters to match what is shown in the following image. These values may vary in your case.

Step 13

We can also place an object beneath the shower of sparks and theparticles will collide with that object. For example, here I have added aSphere beneath the particles.

Step 14

To make the particles collide with the sphere, we need todefine the sphere as a collision object. So, go to Space Warps > Deflectors > UDeflector and drag out a UDeflector icon in the Perspectiveviewport.

Step 15

With the UDefeletoricon selected, click on the Modify tab, and then click on Pick Object and then pick the Sphere in the viewport. Now thesphere has become the collision/ deflector object. 

Step 16

Press6 to open the Particle View once again. Here make a new event with the Delete and Display operators only. Connect the string of the Collision operator from Event 001 to the Event 002.

Step 17

With the Delete operator selected, turn on the By Particle Age option and leave it with the default values. This means all the particles which have lived for 60 frames will be deleted .

Step 18

With the Displayoperator selected, turn the Type into Geometry.

2. Material Setup

Step 1

PressM to open the Material Editor. Select an empty slot and click on the Diffuse channel. This opens the Material/ Map Browser window. Hereselect the Particle Age material andclick on OK.

Step 2

In the Color#1 slot, enter the following values R: 255 ,G: 215and B: 135 respectively.

Step 3

In the Color#2 slot,enter values of R: 255, G: 125 and B: 50 respectively.

Step 4

In the Color#3 slot,enter these values R: 255, G: 100 and B: 35.

Step 5

Copy the same ParticleAge material from the Diffuse channel to the Self Illumination channel as an Instance.

Step 6

Here Ijust put a concrete texture on the sphere to make it look better, and alsoadded an Omni light to the scene.

Step 7

Press 6 to openthe Particle View window, and Insert a Material Static operator into Event 001.

Step 8

Drag and copy the ParticleAge material to the Assign Materialtab of the Material Static operator.

Step 9

Copy the same MaterialStatic operator into Event 002also.

Step 10

With the particle material slot selected, assign a Material ID of 1.This unique material ID will help the particles achieve their glowing effect.

3. Applying Effects

Step 1

Now, Right Click on the Event002 bar and select Properties.This opens the Object Properties window.Here enable Motion Blur with Object mode.

Step 2

Go to Rendering >Effects to open the Effectswindow. Here add Lens Effects.

Step 3

Applya Glow effect as well and set the values for Size to 0.01, Intensity to 145and Source Color to 90. And then change the Radial Color to be a bit orange.

Step 4

Nowclick on the Options tab. Here set the Material ID to 1. This is the same material ID which has been assigned to theparticle material.

Step 5

Render the scene and you will see something like this.

Conclusion

Youcan also animate the particle flow emitter randomly a bit, so you get different results. Play with the particle, force and deflectors values andyou will really get awesome results. Hope you guys have enjoyed this tutorial!
