| TODO | The ''Live Connect'' panel is used to connect/disconnect from DEMoCap running on the same or a remote computer. |
| | |
| | You can enter address in ''Host'' in the following forms to connect to: |
| | ^ Address ^ Description ^ |
| | | ''hostname'' | Listen on resolvable hostname on port ''3413''. Picks the first public IP address found on the host. Depending on your operating system this can be IPv6 or IPv4. | |
| | | ''hostname:port'' | Listen on resolvable hostname using custom port. Picks the first public IP address found. Depending on your operating system this can be IPv6 or IPv4. | |
| | | ''IPv6'' | Listen on IPv6 address on port ''3413''. Address can be in full and shortened form. | |
| | | ''[IPv6]:port'' | Listen on IPv6 address using custom port. Address can be in full and shortened form. | |
| | | ''IPv4'' | Listen on IPv4 address on port ''3413''. | |
| | | ''IPv4:port'' | Listen on IPv4 address using custom port. | |
| | |
| | By default DEMoCap listens on port ''3413''. You can change this port in ''Port'' to match your network setup in [[democap:uipanelsettings#network_access|DEMoCap Settings Panel]]. |
| | |
| | Click the ''Connect'' button to start connecting to DEMoCap. The status is shown in the label below the buttons and can have these values: |
| | ^ Value ^ Description ^ |
| | | Disconnected | Not connected to DEMoCap. | |
| | | Connecting... | Connecting to DEMoCap. | |
| | | Connected: ''Host'':''Port'' | Connected to DEMoCap using ''Host'' and ''Port''. | |
| | | Failed: ''Reason'' | Connection failed for the mentioned reason. Resolve the problem then try again. | |
| | |
| | Click the ''Disconnect'' button to disconnect from DEMoCap. |
| | |
| | Once connected streaming can be used. |

| TODO | The ''Live Actor'' panel shows properties linked to the motion capture actor performing in DEMoCap. |
| | |
| | Set ''Actor'' to the Armature object you want to apply the motion capture streamed data to. The Armature has to match the rig used for the character in DEMoCap. Typically this Armature object has been exported as [[gamedev:deigde:editors:rig|Rig Resource]]. If the Armature does not match the [[gamedev:deigde:editors:rig|Rig Resource]] the result of the stream is wrong. A compatible Armature can also be used as long as the streamed bone animations match. Only bones matching any of the streamed bone data by name are modified. You can thus use the streamed data to partially animate an Armature and mix it with Blender created animations. |
| | |
| | The ''Actor'' property is stored per Scene object. Hence switching Scene switches also the actor shown in this place. |

| TODO | The ''Lice Capture'' panel allows to capture streamed in motion capture data in various ways. |
| <WRAP clear/> | |
| |
| | Toggle the ''Preview'' button to switch on preview streaming. In preview streaming mode the Blender View is periodically updated at the frequency set by ''Rate'' (updates per second). This allows to see see the actor performance in real time in Blender. Preview streaming does not insert keyframes into actions nor does it record with Auto-Keying. |
| |
| | While preview streaming is active you can click the ''Capture Frame'' button to insert keyframes for the last received capture frame. This inserts a keyframe for each bone at the current frame. This can be used to block out animations or capturing individual poses. The same rules apply for Action handling as if you insert keyframes using the <key>I</key> key. |
| | |
| | While preview streaming is not active you can click the ''Record'' button to start recording streamed motion capture data. This starts animation playback at the current frame position and scene frame rate (not the ''Rate'' property). Received motion capture data is written to the closest frame matching the received capture frame time while playing back. DEMoCap does not record at regular intervals but captures frames as the underlying hardware and CPU performance allows. Blender on the other hand has a fixed playback frame rate. Matching these can drop captured frames if falling on the same Blender frame or skip Blender frames. This Add-on ensures the timing of the recorded animation while playing back is correct by skipping frames as needed. Click the button again to stop recording. You can also press <key>Cancel</key> or <key>Space</key> to stop playback which in turn also stops recording. The Blender frame is not rewound after recording stops. |
| | |
| | Toggle the ''Sync'' button to listen to recording state changes in DEMoCap. If toggled and DEMoCap starts recording this has the same effect as manually clicking the ''Record'' button. Likewise if recording stops in DEMoCap recording also stops in the Add-on. |
