When a camera gets too close to a wall and you are suddenly able to see through to another room or the other side. This problem is very common in architectural walk-throughs. This situation can happen when you model an object with very small dimensions and have to come very close with a camera or perspective view. For large scale scenes like streets, airports and stadiums, you might increase this value to 1 unit = 10cm or 1 unit = 100cm. If you work on a tiny scale like seeds of rice, it is recommended to change the System Unit Scale from the default of 1 unit = 1 cm to something like 1 unit = 0.1 cm. These round-offs can also cause some other problems like strange viewport clipping or flipped normals. 3ds Max rounds-off floating points when dealing with extremely large or small distances. If you’re zooming or panning is way too slow or too fast, the most likely problem is the System Unit Scale. Zooming and Panning Are Too Fast or Too Slow Objects disappear when camera gets close.Zooming and Panning are too fast or slow.This may have a significant impact on your scene and therefore, it is very important to always set up correct units before importing any models. If you import a DXF file (which is unit-less) with one box the size of 1x1x1, after importing it can be 1mm or 1km depending on the System Units. Display Units affect only viewport geometry units while System Units determine the actual scale of the geometry. It is important to understand the difference between System Units and Display Units. The unit setup dialog will appear when you click from the main menu Customize > Units Setup > System Unit Setup, then select centimeters and click ok.Īt the Display Unit Scale select Metricand from the dropdown menu select centimeters. Setting up correct units depends on what country you live in and what type of measurements you use (imperial or metric). A better visual experience in the scene.It is very important to understand some of these common mistakes, try to avoid them and remove them from your workflow. One of the most common problems in 3ds Max is the unit mismatch of a model.
