Hey folks!
The first regular update of the year is now available on the beta branch. In this update are two major changes: file paths and video encoding. Each is outlined below, and all of this information will be permanently housed on the #guides channel on our Discord.
Also in this update are all the fixes and catalog additions/changes since our last update in December, as well as tutorial fixes and new Featured Locations from the 0.991 Locations Contest.
Opting into the beta branch looks slightly different now. You still right-click SpaceEngine in your Steam library and hit Properties, but "Betas" is now "Game Versions & Betas", with a more descriptive list of branches rather than a dropdown. "Public" is now "Default Public Version." The "beta" option is still used to join the beta.
File Path Changes:
To bring SpaceEngine more in line with common industry standards, we have made changes to how and where SpaceEngine stores user and cache files.
If you are a casual user and don't want to move files manually, it is recommended that you either remain on the Beta branch during the testing phase or wait for the full release. If you plan to swap branches or play with files during the Beta, it is recommended that you back up your user files (places-user.cfg, main-user.cfg, keys.cfg, etc.) to a separate location so you don't lose anything.
When you first launch post-update, SpaceEngine will detect and move/create files as follows:
The cache (models, shaders, filesys) will be created at %APPDATA%\\Cosmographic\\SpaceEngine. The existing cache in your install folder will be deleted.
If you swap to a pre-0.991.50 version, the cache will be rebuilt in its old location, then deleted again when you return.
Save data is now stored at %USERPROFILE%\\Documents\\Cosmographic\\SpaceEngine. The save-user.cfg and places-user.cfg files go into a 'save' folder, while all other personal .cfg files (i.e., keybinds) go into the 'config' folder. On boot, if no save data is found in this file path, SpaceEngine will first search the Steam install for existing save data, moving any it finds to the new location. For any file it can't find, new files will be generated.
Thumbnails for your custom Locations will need to be regenerated by visiting them again once each. These thumbnails are stored in the 'save' folder alongside your places-user.cfg and save-user.cfg.
Default .cfg files, such as graphical presets, will stay in the Steam install folder. These are not meant to be edited by the user and are now restored anytime SpaceEngine updates.
When you swap to a build older than 0.991.50 (i.e., visiting your old 990 locations), your save will appear to have been wiped, as it is reading from the Steam install config folder again. To restore it, you can either copy or move the .cfg files from the config/save folder in the new file path back to the config folder in the Steam install, overwriting the blank save. Per the new boot logic, if you move the files, they will be moved back when you return to 0.991.50. If you copy them instead, you will effectively now have separate saves for either side of that breakpoint that do not interact. It is recommended that you make a backup of all files you plan to move/copy before you do this.
All future exports, logs, screenshots, and videos will appear in the %USERPROFILE% file path in corresponding subfolders. Existing media files (or any generated in older versions) will remain in their original places.
Logs, such as your se.log, now generate in their own 'logs' folder.
All forms of screenshots, videos, and exports populate together into similarly named folders.
For PRO users, the Camera Path Editor now opens %USERPROFILE%\\Documents\\Cosmographic\\SpaceEngine\\addons\\scripts by default when you try to Save or Load a spline path. For old path files, you will need to manually navigate to the old folder in the SpaceEngine Steam folder each time, or move old content to the new location.
Scripts, catalogs, textures, .pak files, and other addon files are now searched for at three locations: The original locations of SpaceEngine\\data and SpaceEngine\\addons in the SpaceEngine Steam folder, as well as %USERPROFILE%\\Documents\\Cosmographic\\SpaceEngine\\addons. It is recommended to use the third location for ease-of-use. Subscribed addons from the Steam Workshop are unchanged.
If you are a mod/addon maker, you must manually move SpaceEngine\\workshop\\projects to %USERPROFILE%\\Documents\\Cosmographic\\SpaceEngine\\workshop\\projects for your projects to appear in the Workshop Config tool after this update. Content paths can stay as-is, but if you change them to accommodate the modified workflow (i.e., you store your content in the workshop folder), remember to update the file path in the tool as well.
Video Encoding Changes:
A recent update to NVIDIA graphics drivers dropped support for older NVENC SDK versions, causing many users to see a "Function not implemented" error when trying to record. To fix this and future-proof for other hardware, we've updated the version of FFMPEG used by SpaceEngine and added more options for users:
The Video Capture tool (F9 by default) now holds a host of codecs and formats to fit nearly all machines. Not all codecs work with all graphics hardware; you'll have to experiment to find what works best for your setup and needs.
AV1: High-end codec with good performance/quality, but requires modern GPUs (NVIDIA RTX 4000 series, AMD RX 7000 series, Intel ARC series or newer, respectively). Used for high-quality, high-resolution production or streaming.
HEVC (H.265): A high-quality native encoder, similarly ideal for production, but on a wider range of GPUs. May have compatibility issues with playback on some media players/devices.
H.264: Default for the average user. This should work on most manufacturer-supported GPUs.
SVT/AOM Software AV1: Compatible with all machines, but they use the CPU to record. SVT prioritizes performance, while AOM prioritizes quality. These are often considered a last resort for those without hardware encoding support. Users who relied on VP9 may want to switch to this codec.
Hardware encoders further specify NVIDIA, AMD, and Intel Hardware options. If you attempt to record with an incompatible codec, SpaceEngine will output an error and fail to record.
There are now two modes to choose from before capturing. You'll need to experiment to find what works best for your project:
Offline rendering (Fixed FPS): Enter a target frame rate, and SpaceEngine will throttle itself to guarantee that frame rate in the final output.
Added a new 'Asynchronous loading mode,' which will use the full multithreading capabilities of the engine to improve performance, but may show the loading/generation process in the final video.
Streaming (Real-Time): Captures the raw, real-time output of the SpaceEngine window. You can set a framerate limit with or without Vsync if desired. Output quality is heavily influenced by your bitrate preset and will ignore custom values.
Changelog:
Pressing the Screenshot button on the magnitudes toolbar no longer opens the screenshot folder. You must now shift + click to do so (the tutorial has been updated to reflect this)
Disabled the normal functions of edit mode keys while in edit mode, so you can focus on editing
Added new splash screen images and quotes
