Creating Water drops in 3Ds Max (English)

In this tutorial I show you step by step how to create water drops in 3Ds max, as distributed on the surface of the object, set its size and use the MultiScatter plugin, create water material and render test, the correct settings for a render good quality

I have two models on the scene (2 bottles of soda)

These models put 2 types of drops of water, the first small and round, the second to be irregular and large as seen in the following photo.

I’ll start adding the drops to one model and then repeat the procedure with the second model.

DROPLET

CREATE SMALL DROP

Create a 12-sided sphere, change it to Editable polygon. Modifying the lower vertices of such that they are in the half of the sphere. If necessary scale was slightly higher vertices to give more roundness to the small drop.

Put the pin on the bottom of the drop but not reaching the base.

DROP SET TO MODEL

With selected drop creates a Scatter (Menu: Create> Compound> Scatter). In the Pick Distribution Object dropdown click on the Pick Distribution Object button and then click on the model. With the above we have made the drop to the model set (a bottle) then you have to distribute the amount that we deem necessary at our discretion.

DISTRIBUTED SMALL DROP

Takes the following values only for reference as these vary depending on the size of your model and drop you’ve created, so each value adjusted according to your criteria and need.
Start by putting 500 Duplicates to increase the amount of drop that will be distributed throughout the model, make sure that the Parameter Object Distribution Perpendicular option is checked it, so the drop is placed correctly on the model surface.

If the drop is too big or small for the model in Base Scale resizes.
In Distribution Using select drop distribution, in my case is Even better, try the Area and Even.

RANDOM SIZE

In Scaling modify the size of the droplets at different scales by marking Maximun Range Use and Lock Aspect Ratio to uniform scaling on all axes, change the value of X that best suits visually, some drops will get bigger and other smaller.

Thank you 🙂

In the Display tab, check the Hide Distribution Object option to hide the reference mesh modifier to duplicate the Scatter. Make sure the Mesh option is selected. If the display is at 100% you will see all the drops that will be created.
Increase Duplicates value to add more drops, I have risen to 4500, if you see that your computer takes a long time to represent the drops, try decreasing the percentage display.

BIG DROP

CREATE PARRAY

First off momentarily hidden droplets.
Go to Particle Systems and make the stage a PArray (Menu: Create > Particle > PArray), from the drop Basic Parameters click the Pick Object button and then click on the model.
Make sure the Display Viewport is selected Mesh and Percentage of Particles 100%.

CREATING PARTICLE

In the Particle Generation choose Use Total and give it a value of 60, Speed changes the value to 0 and the Emit Stop to 0, the latter will make you see all the drops from the first frame.

DROPS SIZE

In the Particle Size group, set to 0 Grow For and Fade For also put to 0, choose the size of the droplets in Size, for example 5 or you want.
In the dropdown Particle Type, check MetaParticles to the drops of irregular type.

If you see that there are very few drops increases the value Use Total and resizes, I have increased the Total Use 500 and the Size to 7.

QUALITY DROPS

As you can see the drops do not have much resolution (few polygons), to increase the quality uncheck the Automatic Coarseness option, once disabled allow us to change the values in the Evaluation Coarseness group. Decreasing values Render and Viewport, drops increase the resolution, but be careful not to diminish both as this may slow the performance drops first 2 in both test and then down to 1.5.

Remember that these reference values are dependent on the measurements of your model and how you have configured the units 3ds Max.

MATERIAL WATER DROPS

Make visible droplets that hid and open the material editor (key M), create a new material and changes VRayMtl color Difusse to black (0,0,0), Reflect: white, Refract: white, activates the Fresnel reflections, Refract IOR of 1.33.

Ready, set it to 2 drops and Render…

RENDER SETTINGS

FINAL RENDER

another render using the same technique
