Motion Blur with X-Particles
Posted: Wed Oct 04, 2017 8:20 am
Hi Ahmet,
whenever I render a scene with X Particles and add a camera motion blur, calculation times for motion blur increase during animation.
I've appended a super simple scene where new particles are constantly created and old ones deleted
but the amount of particles keeps around 16000 after frame 60 or so, nevertheless mblur times go up constantly
MBlurTM is about 0.4 sec at frame 60 and builds up to about 3.4 seconds at frame 250.
In this small scene the effect isnt as drastic as in more complex scenes but it's the same effect I have on bigger scenes where the MBlurTM starts up with a few seconds and then
goes up to several minutes after a few frames. The more complex the scene is the bigger the effect.
If I stop at a certain frame and start rendering again from that point on everything is reset back to short times but then the increase starts again.
Would be great if you could take a look into that.
Thanks,
Thomas
