just rendering part of the image

[copain]

Hey guys hoping to get some help with this:

 

Here is an image of scene I am rendering, as you can see it has a shadow of a tree( which is animated).

Now my question is, what is the best way to render this?

As there is no camera move it is just the shadow changing, is there a way of just rendering that region?

 

thanks

With Max 2009 Design, you have Render Regions.

Do 1 full render

Switch to Render Region

Marquee the area to render

Press the Go Button

use the letter box technique then

hey stephen

how does that work?

[STRAT]

you put a plain or face directly in front of the camera, and assign a pure black, non shadow/gi emitting, seen only by camera material to it. Then, punch out a hole where the action takes place. then hit render.

Hey Steve,

 

Which trees are you using to get the 'leaves moving in the wind'?

I want to do an animation like that as well. I think it's a cool effect.

Also, are the trees moving with Reactor, or are you keyframing the animation or how?

 

Thanks!

hey Joel

 

I used onyxtree, There is a setting to create a wind effect.

In my case,because you do not even see the tree, I just have a plane with an image sequence on it.
