3DS MAX leaf blur?

[craigbennett]

Here is a pic that is in progress. I'm having trouble getting the falling leaf to show a motion blur. What is an easy way to get the "falling motion blur" to show up correct?

Maybe giving the object a material id to easily select it later in photoshop and apply the blur there.

If you are using scanline renderer, be sure you're not on frame "0." It needs to have a frame before to calculate the motion. BTW, great scene! Maybe a little racked focus would top this puppy off.

I used the MR renderer. I may have to use the scanline if I cant get the MR to produce the blur that I would like.

Is racked focus the same as MR depth of field? If it is not could you let me know and i'll give it a try. I was going to add depth of field to blur the back trees but if racked focus is somthing else I'll try that.

That's the one. On the motion blur, I'll check witha couple guys here and see if they have had similar issues in MR.

I've never tried using Motion Blur on a still image. How does Max know which direction the blur is coming from?

I have mostly tried using the directional option for Blur Type but I'm not able to make it look right. I was just wondering if there was a easy way in Max to add a directional blur that looked good.

Is there an attempt shown in your example? Can you show one? I'll take a look when I get home and see if I can't figure something out...

Forgive me if I'm preaching to the choir here. Motion blur works on a simple process of blending several frames before and after with the "current" frame. Since I'm a v-ray user, I tried to replicate the problem in MR. In order for it to show up a few things have to be in place:

1) The object is animated
2) Mation blur is turned on in the Camera Effects roll-out
3) There are frames before and after to generate the blend (that's why it's typically NOT frame 0.

What I think the issue may be in your scene is that the leaf is not traveling "fast" enough to make the motion blur noticeable. Try closingup your key frames or increase the distance that the leaf is traveling.

Hope that works...
