A site I subscribe to posted a generous list of links to download demo or free 3d models for 3ds Max. Here they are below:
1) A script crashing your session? Increase “heapSize” allocation to give scripts the ability to work with more memory
2) These scripts can help to clean up memory in 3ds Max “gc()”,”freescenebitmaps()”, and “clearUndoBuffer()”
3) Debris maker by Aaron Dabelow is a quick way to add tons of debris to a scene: Click Here
4) Use the semicolon to repeat the last command
5) Create buttons with scripts to quickly apply modifiers used often
6) The cloth modifier can be used to simulate leaves, paper, and more
7) Objects can simulate animation using Trajectories
8) Utilize the display panel to globally control the display of objects and manage a scene more effectively
9) The preview for materials can be customized. Double-click the material to open the preview, then right-click over the preview and select options
10) The Track View located under Graph Editors can be an efficient tool for animating objects
11) A good way to work in real world dimensions is to set your grid at even and snap to it
12) Shapemerge can be used to cut shapes out of a mesh whether it’s text, a circle, or random spine
13) Extract edges to create a wireframe by selecting an editable poly and using the “create shape from selection” button in the command panel
14) Use statesets to present design iterations. Statesets store light, modifiers, viewport settings and more
15) The transform toolbox has great tools for controlling the pivot, and even a button to quickly reset xform
16) With layered cloth animations (such as coats over clothes, stacked sheets, curtains, etc), line up your quads and maintain a similar density in each mesh to insure better calculations for better animation results
17) It can be obvious to recognize when an image used default 3ds Max camera settings. Adjust them with real lens size and settings to get better results
18) Consider freezing CAD references, but remember to add “snap to frozen objects” in snap settings to take advantage of the file
19) You can establish the angle the sun will rise and set on your projects during summer and winter months using the Sunlight tool. You can use that information to create a north arrow unique to your project and analyze your site in more detail.
20) If you are producing a 360-degree video where the camera remains at a static position, to get the best results, render out a single image at high resolution and use quality video editing software to stretch out its time.
21) 3ds Max allows us to create custom quad menus. Additionally, while users are used to the typical menu, we can access more with various key combinations. Hold Control + Alt and click the right mouse button to access render options.
22) An easy way to remove the character’s weapon in 3ds Max Interactive is to simply select it in the Asset browser, open the Unit Editor, and uncheck the “Visible” box.
23) Key to 3ds Max’s Vray plugin is to work with realistic values. Part of that is insuring we choose the correct camera settings. The primary settings for visualization in the AEC industry that need to be considered are shutter speed, f-number, and ISO, all which are part of a real DSLR camera. Below is a chart demonstrating how Aperture (F-number), shutter speed, and ISO work to help make those determinations and get the best quality you can from renderings.
