1. Deal with Geometry
When modeling in 3ds Max or dealing with geometry, always use a 1:1 scale and give elements logical names. It will be far easier to identify “South Wall” than “Box 095” in a complex scene. Use layers and the Group function to group multiple elements together, and when making repetitions of the same thing, create instances instead of outright copies. That way, when you make a geometry or material change on one item, all of the instances will also change accordingly.
In complicated scenes, isolating individual objects (right click > Isolate) will allow you to focus on editing or texturing one individual item while the rest of the scene is hidden.
Use 3ds Max’s populate feature to place large groups of people in your scene from the built-in library. They are pre-animated for slight body movement when standing still or walking motions if placed along paths and are fully textured.
4. Model Efficiently
Move your camera around inside 3ds Max to select desirable points of view and frame shots prior to going into detailed modeling. This way, you will only need to model what the camera can see and will save enormous amounts of time. This will also help to avoid the temptation of wanting to show off all of your painstaking modeling in one unrealistically wide-angled image that attempts to capture the entire scene. Instead, try using narrower-angle lenses, and if you do need to include more of the scene, pull the camera back and use the clipping plane to clip foreground elements from view.
5. Embrace Real-World Photography
Rendering software allows endless tweaking of camera and environment settings to bypass real-world photographic constraints in order to curate a very specific image, but doing this will invariably result in a distinctly CGI look. If you adopt the philosophy of attempting to replicate real photography, your images will begin to take on a photographic quality.
6. Master Rendering
If you are using a specific render engine (such as V-Ray), ensure that all the scene materials are optimized for that particular engine. Thus, you avoid strange behavior in materials and lighting when you render.
7. Create Realistic Objects
Look to the world around you for clues of how different materials and surfaces behave under varying light conditions. You would rarely find completely pure blacks or whites in the natural world, so avoid using the pure black RGB value of 0, which will absorb all of the light that hits it, and the pure white RGB value of 255, which will reflect all of the light.
8. Use Realistic Lighting
Base your lighting setup on real-world environments and your material texture and color will appear far more convincing. Take a photograph in an environment similar to that which you are rendering in automatic mode and note the shutter speed, aperture and ISO speed that the camera uses. Apply these values to the Physical Camera inside 3ds Max and tweak your light-source (for example, your HDRI or Sun) intensity until the resultant render’s lighting levels resemble those in the real photograph. Now you have essentially established a lighting setup that uses real-world values, and you can adjust the Physical Camera’s settings to control the lighting as you would do to take the real photograph.
You may still need to add fill-lights around the scene to highlight certain elements, but their intensity will now have a realistic basis, and you will avoid heavily blown-out areas and over-the-top reflections. Remember that the more light sources and reflective materials you have in your scene, the longer the render will take to complete.
9. Optimize Your Output
Always save your renders as 32-bit TIFF files and never JPEG. JPEG is a compressed format and will restrict the amount of information you can deal with in post production. A 32-bit TIFF is an uncompressed file and will allow you far greater control over post production lighting and exposure adjustment.
10. Update and Save
3ds Max is a very complex program. Regularly check for the latest service pack to ensure any updates and bug fixes are implemented.
