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
1/1,048,576th
- 100
1/131,072th
- 1,000
1/16,384th
- 10,000
1/1,024th
- 100,000
1/128th
- 1,000,000
1/16th
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.
