Hi there,

I am using the motion blur option on one of my objects in my animation, at the moment i am rendering the animation, but the problem is that when its rendering a certain part of the animation, the whole of the scene is blurred, not just the object that i put a blur onto, is this just the way the blurred option renders, and will everything be ok?

thanks

Hi edd,
well without any referenz noone will be able to help you, cause we can´t see what you did, but if I understand your your probleme right, you wanna make a object blurry itself and the rest of the scene uneffected by the blur right?
If yes, I think you rather wanna use Depth of field on the object.
I´m not sure and still more of a newbie myself, but I think DOF (Depth of Field) will be best for what you wanna do.
But thats my oppinion and an oppinion without seeing what you are doing.

I cant actually show you just now, because its in the middle of a rendering.

Hopefully thats just the way blurring renders the scene, and only affects the object that is meant to blur.

When i think about what i done, i had to actually select an object before the option became available to me, so that means that the object that was selected has the blur, right?

if anyone could help, that would be much apprecited

thanks

as far as I know motion blur is scene wide, ie. it affects all the objects in the scene so you might be better off using the DOF option. However, I could be wrong, it has happened before.

Hi there

My animation has a plane involved in the scene, and i was wanting the propeller to have some sort of blur on it, this is to get the effect that the propeller is going faster, but i do not want any other object in my scene affected, just the propeller, how would i go about achieveing this?

I have already tried the motion blur and the vector blur, but this affects everything around it.

thanks

if the motion blur affects everything it's because your CAMERA is moving,
else it's that all your objects are moving…

If you need to apply motion blur only on one object and if it's clear that the
blur does not depend on the distance to the camrea (which is DOF),
then you only have one solution : compositing.

render separately your scene and your object with alpha channel (32 bits image),
stack them in Photoshop (or compo app if it's animation) and then apply your blur to your object…
Other solution, also with compositing but without to set the blur in the compositing app :
- Render the scene with motion blur DISABLED
- Render your object only with alpha channel, with motion blur ENABLED
- composite both images…


hope this helps
