# B0005

A runtime warning.

Separate font atlases are created for each font and font size. This is expensive, and the memory is never reclaimed when e.g. interpolating `TextStyle::font_size` or `UiScale::scale`.

If you need to smoothly scale font size, use `Transform::scale`.

You can disable this warning by setting `TextSettings::allow_dynamic_font_size` to `true` or raise the limit by setting `TextSettings::max_font_atlases`.
Warn instead of erroring when max_font_atlases is exceeded (#6673) # Objective Fixes #6642 In a way that doesn't create any breaking changes, as a possible way to fix the above in a patch release. ## Solution Don't actually remove font atlases when `max_font_atlases` is exceeded. Add a warning instead. Keep `TextError::ExceedMaxTextAtlases` and `TextSettings` as-is so we don't break anything. This is a bit of a cop-out, but the problems revealed by #6642 seem very challenging to fix properly. Maybe follow up later with something more like https://github.com/rparrett/bevy/commits/remove-max-font-atlases later, if this is the direction we want to go. ## Note See previous attempt at a "simple fix" that only solved some of the issues: #6666 2022-11-25 23:49:25 +00:00			`# B0005`
