What is the RPS file format?
.rps is a Render Preset Settings file used by Autodesk 3ds Max and the now-discontinued Autodesk VIZ. .rps files store 3D graphics rendering settings - including output resolution, anti-aliasing filters, motion blur, color mapping, and global illumination parameters - so that a complete renderer configuration can be saved and reloaded quickly.
.rps files allow reuse of rendering settings across various 3ds Max projects and support project standardization within studios. Multiple renders can be produced based on different presets in order to select the best result. Presets can also be shared with other users working on different projects.
A key detail is that presets are renderer-dependent: an .rps saved while Arnold is active stores only Arnold parameters and will not populate V-Ray, Corona, or Scanline settings. 3ds Max ships several factory defaults for the Scanline renderer - Draft, Low, Medium, High, and Very High - accessible from the Rendering menu via Render Presets. User-created presets are saved to %LOCALAPPDATA%\Autodesk\3dsMax\<version>\ENU\renderpresets\.
The format is a proprietary binary file with no public specification, identified by the .rps extension alone. It is Windows-only. Related Autodesk formats include .max scene files and .mat material libraries.
Security & safety
RISK: LOWSettings-only binary file; cannot execute code. A malformed .rps could potentially cause 3ds Max to crash on load but poses no operating-system-level security risk.
Format details
in a nutshell- Adobe RoboHelp Project Settings File - Adobe RoboHelp (help-authoring tool) uses .rps for project-level configuration; unrelated to 3D rendering.
- Esri ArcPad Map Project File - Esri ArcPad (discontinued mobile GIS application) used .rps for map project data files.

Paid Rendering menu → Render Presets → Load Preset, select the .rps file, pick parameter categories in the dialog, click Load. Technical details
deep spec| File encoding | Binary, little-endian byte order |
| Container format | Proprietary Autodesk binary container; internal structure is renderer-plug-in-specific and not publicly documented |
| Typical file size | 5 KB - 500 KB depending on the active renderer and number of stored parameters |
| MIME type | application/octet-stream (no registered MIME type specific to the format) |
| Operating system | Windows only; 3ds Max has no macOS or Linux version |
| Renderer dependency | Preset parameters are specific to the active renderer; an .rps saved with Arnold does not populate V-Ray, Corona, Redshift, or Scanline settings |
| Stored parameters | Output resolution, time range, anti-aliasing filters, motion blur, color mapping, global illumination, caustics, and renderer-specific sampling settings |
| Selective parameter loading | When applying a preset, 3ds Max presents a category list so users can choose which render parameter groups to overwrite, leaving others unchanged |
| Factory preset location | <3ds Max install>\renderpresets\ subdirectory; ships with Draft, Low, Medium, High, and Very High defaults for the Scanline renderer |
| User preset storage path | %LOCALAPPDATA%\Autodesk\3dsMax\<version>\ENU\renderpresets\ |
| Version compatibility | Versioned per 3ds Max release; presets from newer versions may not load correctly in significantly older builds |
| File identification | No magic bytes or public file signature; identified by the .rps extension alone |
| Access in 3ds Max | Rendering menu → Render Presets → Save Preset or Load Preset (available since 3ds Max 6) |
| Supported applications | Autodesk 3ds Max (current); Autodesk VIZ (discontinued ~2007); no documented third-party support |
| Compression and encryption | None; the file is a raw binary dump of renderer parameters with no compression or obfuscation |
| Released | Approximately 2003 with 3ds Max 6, where Render Presets was formalized in the Rendering menu |
| Latest version | Compatible with 3ds Max 2026 (current) |
