I think that with Path tracing, the most important feature is in the movie capture tab:
Path Trace samples per pixel
fire 1 - 3 samples:
fire 2 - 10 samples:
fire 3 - 30 samples ( average render time per frame 5 sec. ):
fire 4 - 60 samples ( average render time per frame 10 sec. ):
But 4 crashed machinima after rendering 129 frames, so I guess it´s not a good idea to crank this setting that high… ?
I continued by tweaking the Anti-Aliasing:
fire 5 - 30 samples ( average render time per frame 5 sec. )
Path Trace samples per pixel 30
Render settings / Path tracing / anti-aliasing sample pattern: gaussian
Render settings / Path tracing / anti-aliasing radius: 1
Alredy this little thing made the render to look as good as fire 4, but with 50% faster render time
fire 6 - 15 samples ( average render time per frame 2.5 sec. )
Path Trace samples per pixel 15
Render settings / Path tracing / anti-aliasing sample pattern: gaussian
Render settings / Path tracing / anti-aliasing radius: 1
BUt again machinima crashed frame 186 :(
fire 7
Render settings / Path tracing / anti-aliasing sample pattern: uniform
no good - a lot of aa problems.
fire 8
Path Trace samples per pixel 10 ( average render time per frame 1.7 sec. )
Render settings / Path tracing / anti-aliasing sample pattern: gaussian
Render settings / Path tracing / anti-aliasing radius: 1
Ok I stick to this for now. I hope I do not get render crashes.
fire 9 ( average render time per frame 1.7 sec. )
Path Trace samples per pixel 10
Motion blur ON
motion blur settings
subframes per frame 5
fire 9 half-shot ( average render time per frame 2.5 sec. )
So people, tell me what to do to make that tiny aa flickering away?
Or do I just wait until we get the possible update to Iray in Machinima?
Next I bring in the fire! But that´s a different topic :)
