Working out how to use Source Filmmaker takes time and involves plenty of small discoveries. Even if a use for these discoveries is not immediately obvious, it could come in handy later.


GeneralEdit

  • SFM disables sv_cheats each map load. If it is not re-enabled, the rendering dialogue can experience errors (such as a negative percentage) and produce invalid video files

Dme Element EditorEdit

  • You can shift the position of individual takes - eg. if you wanted a scout to get blown up by a rocket but mis-timed it, you don't necessarily have to re-record it
    • Browse to "clipBin/sequence/subClipTrackGroup/tracks/Film/children/shot/scene/children/take*/transform", where take* is the relevant take. You can then edit the position to shift the recording
    • Note that this affects everything in that take, including world objects like medpacks and doors. If you want to affect individual takes, expand take*/children, find the relevant model(s), then adjust their transform/position
  • Some of the editor's settings are stored in the Dme Element Editor - this includes things like the position of the handles in the animation set editor and even the colour overlay when you start using the animation set editor

Interpolation MethodsEdit

  • The Dme Element Editor allows access to a feature that is not available in the GUI (as far as I can tell) - the interpolation method the Animation Set Editor uses. Usually it applies a linear interpolation within the handle's falloff area when using the sliders. However, there are other options available:
    • Note: Invalid options seem to default to Ease
    • Note: Sometimes it refuses to change the interpolation method. Select another field and then try again
    • Note: Directions (start and end) are written relative to the left interpolator. That is, "start" is farthest away from handle, "end" is closest
    • 0 - Steeper Ease (not sure the "real" name of this one)
    • 1 - Variation on Ease
    • 2 - Ease In (changes fastest at start, slowest at end)
    • 3 - Ease Out (changes slowest at start, fastest at end)
    • 4 - Ease (changes faster in the middle than at either end)
    • 5 - Linear with offset (jerks slightly at start and end?)
    • 6 - Linear (default)
    • 7 - Several of these are slight variations on the Ease method
    • 13 - Polynomial (basically, it creates a "bump" of the max value in between the start and end of the falloff area. Looks pretty glitchy, not to mention it causes overlap on the GUI)
    • 14 - Much more dramatic Ease Out
    • 15 - No interpolation
    • 16 - Ease variation. This seems to be the last valid option
  • To use any of these, just enter the valid number in settings/timeSelection/interpolator_left or settings/timeSelection/interpolator_right. While you're at it, you can also control the exact position and falloff size of the handles (times are in 10s of milliseconds. 10000 is 1 second)

Expression field commandsEdit

  • This is a list of known commands for expression fields, along with their arguments
  • Note that if you enter an invalid expression, it evaluates up to the point of error. For example, the expression "1+sign(-)+4" equals 1, as it stopped evaluating when it encountered the missing argument
  • Similarily, you must close all brackets correctly
    • General Number-Work:
      • round( val ) - Rounds to the nearest whole number ((val-val%1>=0.5) ? val%1+1 : val%1)
      • ceiling( val ) - Rounds up
      • floor( val ) - Rounds down
      • sqrt( val ) - Returns the square root of the number
      • sqr( val ) - Squares the number (val*val)
      • abs( val ) - Absolute function. Makes the number positive ((val>0) ? val : -val)
      • pow( val, power ) - Raises val to a power
      • exp( power ) - Raises e to a power
    • Trigonometry:
      • rtod( val ) - Converts value from radians to degrees
      • dtor( val ) - Converts value from degrees to radians
      • sin, cos, tan( val ) - They all do what they say on the tin. Value must be in radians
      • asin, acos( val ) - Take arcsine / arccosine of value
      • atan2( y, x ) - Returns angle (in radians) from positive x axis to vector (x, y)
    • Logic:
      • Note: Unless otherwise stated, logic functions return 1 or 0 (true or false)
      • sign( val ) - Returns the sign of the number (1 or -1). 0 is considered positive ((val>=0) ? 1 : -1)
      • max( val, val2 ) - Returns the larger of the two numbers ((val>val2) ? val : val2)
      • min( val, val2 ) - Returns the smaller of the two numbers
      • inrange( val, lo, hi ) - Returns 1 if value is larger than/equal to lo and smaller than/equal to hi. Note that lo should be smaller than hi (val<hi && val>lo)
    • Scaling:
      • lerp( val, lo, hi ) - Linearly interpolates a value from 0-1 to lo-hi. Note that it accepts any value, so -1 will return -hi (lo+val*(hi-lo))
      • clerp( val, lo, hi ) - Clamps val from 0-1 before linearly interpolating (lerp(clamp(val,0,1),lo,hi))
      • ramp( val, lo, hi ) - Returns the "position" between lo and hi that val is, scaled to 0-1. Note that if val is not within the range you may get #INF as a result ((val-lo)/(hi-lo))
      • cramp( val, lo, hi ) - Clamps val from lo-hi before determining its "position" using ramp (ramp(clamp(val,lo,hi),lo,hi))
      • clamp (val, lo, hi) - Clamps the value to the range lo-hi. Note that lo should be smaller than hi ((val>hi) ? hi : ((val<min) ? min : val))
      • rescale( val, lo, hi, newlo, newhi ) - Scales a value from one range to another. Note that order is very important ((val-lo)/(hi-lo)*(newhi-newlo)+newlo)
      • crescale( val, lo, hi, newlo, newhi ) - Clamps the value before rescaling it (rescale(clamp(val,lo,hi),lo,hi,newlo,newhi))
    • Unknown:
      • elerp( val, lo, hi ) - I'd expect this to be exponential interpolation, but I've seen no difference from lerp within val range 0-1 and it's gone weird outside of that. lo and hi cannot be 0 (lo*pow(hi/lo,val))
    • Not Tested:
      • noise
      • modf
      • ceil
      • atan
      • exp10
      • log10
