How do you keep a character in the cockpit with the airplane moving?

You don't move the plane, you move the background. Ziggy did an excellent tutorial on this:


It's for a car but you can apply similar logic.

In this video I only move the camera :-)

yeah, for a plane scene, if you put clouds on a backdrop, and set the backdrop's animation to move the clouds toward the tail of the plane, even though the plane is not moving, the relative motion between the plane and the clouds will create the illusion that it's the plane that's moving past the clouds, instead of the other way around.

You've already noticed that trying to move the vehicle causes other problems, so in muvizu moving the background is generally an easier and more controlled way of getting the effect you want.

But it *IS* possible to move vehicles too. It all depends on how you you choose to present the scene to your audience. Creativity goes in every direction. ;-)

I guess the standard wise guy response would have been "SEAT BELT" ;-)

Thanks, Pat. I was hoping to be able to lock the two items. Thanks for the example too. Now, I just gotta find a spinning propeller!

Now, I just gotta find a spinning propeller!


here are some workarounds for the spinning propeller problem.. I'm sure there are a thousand ways to skin this cat, and others will have better ideas.. but this is a starting point

1) since you can't really SEE the actual propeller when it spins (its just a blur of motion) you could create a circle in your 2D graphics program... put it on an alpha background... color the circle white, then reduce its opacity to about 50%. That way you'll be able to see thru it (as would be true of an actual moving propeller) but there would still be enough opacity to reveal the circular shape of the propeller and its path. Save the graphic and use it as a texture on a square backdrop located at the front of your plane. This is probably the easiest way to simulate a propeller... but not the best looking.

2) another way would be to draw or download a propeller . Load it into your 2D graphic editor onto an alpha background, and save a copy as PNG. Then rotate the graphic a little bit, being careful to keep the center of it in the same place. Continue rotating and saving until you have a full 360 degrees of rotation. Name the series of saves something like prop0001, prop0002, prop0003, and keep them together in the same folder. If you're lucky, Your video editor may open the folder as a video and let you save it as an AVI animation, which you can then use as a texture on a backdrop, same as example #1, only in this case it won't be a static image.

3) a third option might be to see if you can find or model a 3d prop, and use keyframes to move it in the Muvizu environment.

4) yet another option might be to search free video archives for a snippet of a rotating propeller, then use it the same as in example 2 (minus the hassle of having to create the animation)

5) and yet another variation on a theme might be to start with idea #1, then in a higher video layer, add brief shots of a still prop at various angles. If you keep the still shots almost subliminally short, it will create the illusion of the stop motion you see when blinking while observing a moving object. It will be more realistic than idea #1 alone, and without the hassle needed to create a full blown video.

I've had trouble in the past with rotating objects in Muvizu, it seems they have a 360 degree limit, so you could turn it once, but you might have to turn it back again. Animating it with the old system may still work though.

did you experience that with keyframes? if so, hmmmm.
But, if that's true, by putting the prop in its own layer all you need is one 360 degree rotation exported as video to use as a backdrop texture, and the perpetual animation will take care of it

You know, it seems like somebody would have created a spinning propeller and put it in the store by now. Same for spinning wheels on a car. There's all sorts of boiler-plate scenes that come up all the time that would be greatly appreciated in an accessory pack

Which prompts a question: if a set contains a backdrop with an AVI animation of a spinning prop or a rotating wheel... could that backdrop/animation be saved in favourites and used again in other projects? If so, that would be a good way to put these solutions in a SET that could be made available to others.

I just remembered you might still need to refer to this tutorial for transparent avi in Muvizu:

Wow! Thanks for that valuable tip. That could be useful in a lot of ways.
