Working Limits

Space

While object positions, vertex locations are not clamped, larger values become increasingly imprecise. To get an idea of the precision you can work with using different scales. Here’s a table of scales and their associated accuracy:

10

1/1,048,576^th

100

1/131,072^th

1,000

1/16,384^th

10,000

1/1,024^th

100,000

1/128^th

1,000,000

1/16^th

Hint

For a rough rule of thumb, values within -5,000/+5,000 are typically reliable (range of 10,000). Internally single precision floating-point calculations are used.

Time

The maximum number of frames for each scene is currently 1,048,574, and allows for continuous shots for durations of:

24 fps

12 hours, 8 minutes.

25 fps

11 hours, 39 minutes.

30 fps

9 hours, 42 minutes.

60 fps

4 hours, 51 minutes.

Note

In practice, a finished work is typically composed of output from many scenes. So this limit does not prevent you from creating longer works.

Text Fields

Fixed strings are used internally, and while it is not useful to list all limits, here are some common limits. Used for data-block names, modifiers, vertex groups, UV layers…

directory

767

file-name

255

file-path

1023

identifier

63

Note

Multi-byte encoding means some Unicode characters use more than a single ASCII character.
