+void ADD_CAM_SPLINE_NODE_USING_CAMERA(Cam cam, Cam cam2, int length, int p3);

+Takes a camera and uses the information from it as a camera spline node. 
+
 
 ## Parameters
-* **cam**: 
-* **cam2**: 
-* **p2**: 
+* **cam**: Camera to add cam2 as a node to
+* **cam2**: Camera used for reference
+* **length**: Duration used for transition, has no effect for the first node.
 * **p3**:

 void SET_CAM_SPLINE_SMOOTHING_STYLE(Cam cam, int smoothingStyle);
 ```
 
+Sets the smoothing style for a DEFAULT_SPLINE_CAMERA
+Ranges from 0 to 3 in rockstar scripts although there are actually 26
+```
+0: No lead-in or lead-out smoothing
+1: Smooth lead-in
+2: Smooth lead-out
+3: Both lead-in and lead-out are smoothed
+4-6: Longer speed up, lead-in, lead-out, and both in order as above. 
+6: see above, but missed a node in testing(?)
+7: Smoothed lead-in, longer smoothed lead-out
+8: Longer lead-in and lead-out than 6, didn't drop node
+9: Constant acceleration
+10: Constant deceleration. Dropped 2 nodes in testing.
+11: Same as 0
+12: 10 but slower lead-in, reaches end node less early
+13: Extremely close to 3, slightly longer lead-in/lead-out
+14: Constant acceleration, dropped last 2 nodes in testing and halted (?)
+15: Very similar to 10, did not drop any nodes.
+16: Long lead-in, dropped 2 nodes in testing, very long leadout.
+17: Constant acceleration, slower speed-up than 9
+18: Same as 17 is to 9, slightly longer lead-out, lingers at end node
+19: Very long lead in and out
+20: Very long, gradual lead-in acceleration at start, gets extremely fast
+21: Same as 20 but for constant deceleration
+22: 20 and 21 combined, long linger at end node. Dropped 2 nodes in testing
+23: Constant acceleration, doesn't complete path before it stops
+24: Same as 23 but with constant deceleration, but completes path
+25: 23 and 24 combined, insanely fast at middle.
+26: No noticable lead-in, misses last 2 nodes in testing
+27+: Alternates between 0 and 26
+```
 
-## Parameters
-* **cam**: 
-* **smoothingStyle**: 
+The above is documented and graphed at [Spline Cam Interp Graphs](https://docs.google.com/spreadsheets/d/1ejyiMcEYrhhQOL0mLe8664UN-vU4Oh-SBqQnVcKlFIk/edit?usp=sharing)
+
+```
 
+Using 1-3 will result in misalignment from the passed durations for the spline nodes, the overall duration will remain but other nodes will be shortened if smoothing anything.
+
+Graph below demonstrates interpolation between 0-1000 and back 10 times.

+
+## Parameters
+* **cam**: The DEFAULT_SPLINE_CAMERA to apply the smoothing to
+* **smoothingStyle**: 0 to 3, 0 no additional smoothing, 1 smooth lead-in, 2 smooth lead-out, 3 smooth lead-in & lead-out
