[BUG] Camera Motion blur not working/enabled

Post by Doug Armand » Thu Jan 26, 2012 9:23 pm

Object motion appears to be working, although there might be a problem there too see last paragraph, but camera motion blur definately isn't.

To clarify what I mean - in the real world a tracking camera should show the ground its moving over as blurred depending on shutter speed and the distance to the camera sensor. This doesn't seem to be working/enabled.

A few examples below - in all the camera is exactly tracking the cyclinder on the x axis and the cylinder has a rotation on the y axis. In all shots the ground is sharp.

1/30 sec exposure

1 second exposure
To me it also appears that object motion blur is not being calculated accurately because if you look at the 1sec exposure there is both rotational and movement blurring but since the cyclinder and camera are in the exact same position there should only be rotational blurring - I'm guessing this might be Indigo's fault and it might be extrapolating movement between frames without taking into account camera/object positions? but then I'm no expert and all that stuff is way over my head - I'm just an artist finding fault with his tools :wink:

I seem to remember Camera moblur is not fully implemented yet - I will look into the issue.
