In this tutorial, we will make a water surface which will match to a Background Image with water. Although there is a way in 3dsmax to do match the geometry with relevant background image (which is called Camera Matching), I am not going to use that method. Rather, I will use simpler technique to achieve this basic result. However, Camera Match system has its own appeal in the complex cases.

Press ‘8’ in your keyboard to open the Environment and Effects dialogue box.

Click on the None button under Environment Map and choose “Bitmap” in the Material/Map Browser window.

Navigate to the “Backgrounds” folder under your 3dsmax’s root directory > Maps which is the default maps installation folder of your 3dsmax program.

Now, highlight “LAKESIDE.JPG” and click Open button.

Although the image has been set to be rendered as the background we will need to set it up as the Viewport Background as well to aid our scene arranging process. For that, activate the perspective viewport and press ‘ALT+B’ in the keyboard. Then check both “Use Environment Background” and “Display Backgrund”. Click OK.

Now, you should see the Image in the Perspective view.

We will now set up a camera to assign it to the Perspective viewpot. Choose Create > Cameras (Standard) > Target and then drag in the Top viewport to place a camera. Go to Perspective viewport and press ‘C’ in the keyboard t assign the camera to the view.

While the Camera01 is still selected go to the Modify panel and check “Show Horizon”.

Showing horizon will let you see a black horizontal line in the camera viewport which represents eye level. It will facilitate to adjust the camera. You may see anothere same looking line in the view before showing horizon. But that is grid line, not the horizon line.

Create a box in the Top viewport as shown. This box will be our water surface matched to that of the background image. You could also use a Plane instead of the box.

Now maximize and adjust the Camera01 viewport (using Truck/Orbit/Dolly tools located at the lower-right navigation area) so that the water surface box is set with the background images’ water portion.

Name the box as “water surface”. Then press ‘M’ in the keyboard to open the Material Editor.

The first empty slot should be selected by default. We will now make a water material with this one. Set Specular Level = 102 (approx.) and Glossiness = 49 (approx.).

Go down and expand the Maps roll-out. Then click the None button in the Bump slot. In the Material/Map browser window, choose Noise.

In Noise Parameters, set the Size value = 5. It may be adjusted further later on while having a look on the rendered result for the water.

Now, assign a Flat Mirror map to the Reflection map (just under the Bump slot). Flat Mirror is good enough as water kind reflection map.

Under Distortion group, increase the Distortion Amount value to 2 To get enough noisy reflection. And to match the reflection with the Bump look choose “Use Bump Map” option.

Our Water Material is ready. Apply this material to the water surface in the viewport.

Quick Render the Camera viewport to see the resulting water surface.

If you want to animate the water, turn ON the Auto Key mode and go to the last frame. Then, in the Material Editor > Noise map’s ‘Noise Parameters’ roll-out, set the Phase value = 10. Now, if you render out the animation in an .avi file you will be able to see that the water is being animated with its waves.

Tips:

1) If the waves of the water surface seems to be bigger than it should be, lower the Size of the Noise under Noise Parameters in the Material Editor.

2) If the water seems to be too bright, change the Diffuse color of the Water material to a darker (more black) one.

3) Feel free to play with other parameters as well.
