RTM
Arma 3 animation export options
For information about preparing an animation for export to RTM, visit the RTM setup page.
Location
File -> Export -> Arma 3 animation (.rtm)
The option is only available if:
there is an armature selected in the scene, with 1 bone at least
the selected armature has an assigned animation action
there is a skeleton definition in the scene data
Properties
Static Pose
Export the currently selected frame as a static pose.
Force Lowercase
Export all bone names as lowercase.
Skeleton
The skeleton definition to use to filter out control bones. The casing of bone names also defines the casing of bone names in the exported RTM file.
Start
Start of the frame range to export. (The value is updated to the Start value of the rendering range every time the export dialog is opened.)
End
End of the frame range to export. (The value is updated to the End value of the rendering range every time the export dialog is opened.)
Source
Source of frame sampling.
List: sample the frames defined in the frame list of the active animation action
Sample With Step: sample frames between the Start and End frames with the given step
Sample With Count: sample given number of frames between the Start and End frames
Since only whole numbered frames can be sampled, the number of actually exported frames can be lower than the set count for the Sample With Count option.
Process
armature bone names are collected and added to an intermadiate RTM data structure (only those bones that are defined in the selected skeleton definition)
motion vector is read or calculated and set in the data structure
frames are added to the data structure
frame indices are gathered
frame indices are collected with the set sampling method
if no frames could be sampled, the export proceeds as static pose
for static poses, the frame currently selected in the timeline is exported (as phase 0.0 and 1.0)
for all RTM frames, the transformation matrices of all bones are added to the data
data is written to the output file
