The new motion blur plugin is terrific, I really like what it offers. In trying it out, I came across one subtle thing that I wanted to pass along. Typically when rendering in blender, I would end up using a motion blur factor of 0.5, which visually seemed to give a very believable amount of motion blur. Using that value was the equivalent of saying that the camera shutter speed was twice as fast as the frame rate. When using a motion blur factor of 1.0, it seemed like too much motion blur - as if the camera shutter speed was equivalent to the frame rate, or that the camera shutter was open for the entire duration of the frame. This would be a very unrealistically slow shutter speed. I found the same thing with the motion blur plugin. With a length of 1, I found myself wishing I could set it at 0.5. Anyway, made a couple small changes to motionblur.C so that the length (or radius) was the integer number of half frames when actually computed. So with this change and with the length set to 1, there was the value of 0.5 that was desired. I ended up using steps set to 15 to get a non-stuttering looking blur and it really came out very nice looking. Thanks for the new plugin, hope this was helpful commentary. Below is the result of a diff, admittedly crude but functional. Greg Mekkes diff motionblur.C motionblur.C-orig 382,383c382 < float fradius = config.radius * 0.5; < float zradius = (float)(zd * fradius / 4 + 1); --- > float zradius = (float)(zd * config.radius / 4 + 1); 394,395c393,394 < x_offset = (int)(xd * fradius); < y_offset = (int)(yd * fradius); --- > x_offset = (int)(xd * config.radius); > y_offset = (int)(yd * config.radius);
