Hi. I'm still really new to this. How would I create a simple "matrix" like motion using the camera? I want the character to jump up, then the CAMERA rotate around like a "matrix" movie. I tried moving the camera, but that didn't work. What am I doing wrong?

Thanks.

You could "aim at" constrain the camera to the object so that when you move it it will remain pointed at the object.

If you need the camera to make a perfect circular arc you should create a null in the same spot where your character is, then "translate to" and "aim at" constrain the camera to that null. Rotate the null and the camera will move around it and stay pointed at it.

TAoA:M explains how to create constraints.

Ok. I did the "aim at" and focused it on the characters chest.

Here's what happened:

I moved the camera a little, adjusted the frame, moved the camera, adjusted the frame...etc...until it went 360 around. After rendering it, two things I noticed:

1: camera didn't move
2: the frames ended at 4:29 ( I had ended the last camera shot at 5:07, so no camera movement)
3: during the "prerender" the camera did move, but the character stayed in place looking AT you. So basically, only the camera moved AROUND instead of YOU moving WITH the camera.

Sorry for this. I'm looking at my tutorials (the new A:M 2007 and trying to find others as well.) I appreciate your help! I know it's probably something simple too...always is!

Another thing I noticed, is when I render to a file, the "VIEW" that I have when I click render, is the view I will see in the render mode, not what the camera "sees".

That's so you can render something other than the camera view if you want.

hit "1" on the number pad to select the camera view before you go to render.

Your description sounds like you're not rendering the camera view.

perhpas the render range was not set to go to 5:07

sounds like you're not looking thru the camera view

Always make sure before you go to render that the very last view you are looking at is the camera view (num1) When you tell A:M to render...you are telling it to render what you are currently looking at. So, if you are looking at the left view (num4) A:M will think you are asking to render that view.

Sample PRJ, camera rotating around Thom and pointing at him.

thanks guys! It's starting to work. Lots of cleanup and touch up, but the basic idea is shaping up.

thanks again!

Hi folks,

Couldn't the camera movement be done on a path ?

1. Aim and constrain the camera to the subject.
2. Create a circular path - this could also support the characters lifting up into the air (?)
3. Constrain the camera to the path.
4. Go !

I saw something similar on the Siggraph video with racing cars that allowed a 360 pass on the start line ...

It just sounds easier ?
Paul Forwood
Yes, you can use a path.

1) constrain camera to path, set ease to 0
2) constrain camera to "Aim at" a bone in an object or a null
3) move to your last frame and adjust the ease of the path constraint to 100, or to suit your requirements.

Crud. Now i'm getting an exception error when I save my project. And any project for that matter. Anyone know of this issue? I posted in the "reports" section.

"Exception #005 - Saving. Attempting to continue but this object may have saved incorrectly. Bush2- objects"

ugh.
