Camera Resolution Mod is a modifier for 3ds Max, created by BodyulCG, that lets you set the render resolution for each camera individually. The current release is version 1.10.1, last updated in June 2023.
The modifier works with presets, which can be renamed and updated, and includes a "Move Time Slider" option. Its recent changes added support for 3ds Max 2024 and fixed an error reading "Attempt to access deleted modifier" that appeared when closing 3ds Max.
Compatibility spans a wide range of releases, from 3ds Max 2010 through 2024. BodyulCG develops scripts and tools intended to make everyday work in 3ds Max faster and simpler, and Camera Resolution Mod is among the entries listed on ScriptSpot.
