Spinning prop

[Ed Doyle]

This is a problem that arises from time to time as you all know. The spinning prop.

Here’s how I handled it. I created a three frame action. I rotated the bone prop this way.

Frame 0: 0 degrees.

Frame 1: -120 degrees.

Frame 2: -240 degrees.

( the plus or minus determines the direction of rotation, I wanted it clockwise from the pilot’s point of view)

I added 10 percent blur. (Default is 20)

But I was still getting a solid prop. To overcome this I made the blades 85 percent transparent.

 

But in the action I only rendered frames 0 and 1. I did this because the blur won’t show up on frame 3.

 

I’ve enclosed a single frame image as well as the action.

(Don’t mind the model, it’s far from finished)

Ed,

 

Yes, props seem to be a problem for many...

Are you aware of the thread about MUFOOF by Xtaz?

 

Therein lies the key perhaps for spinning a prop... and even showing the Nyquist rate of revolution....

 

Pretty cool stuff, that may help... take a look, click on the underlined link above

Thanks Charlie. That's what I was looking for, but I couldn't find it.

Much much better than what I did.

How did I ever miss that thread. The information in it is amazing. Xtaz, wherever you are, Thanks.

Ed,

 

On my c-130 model I used the prop rotation expressions shown on other threads plus an action file like yours (I made a 24 frame animation though)

I then made them I alos made a prop rotation disk, a disk that is decaled to look like a prop already rotating, then I made them transparent to a % , as The prop starts slowly rotation up using the actions and/or expressions I slowly switch from props to rotation disk using traansparency, props solid at begining and disks 100% transp. then reverse the transparency as the prop rotates faster,

Cool looking aircraft so far....

Thanks Michael, I'll try your way too. I'm not much of an animator, but I like photo realism, and am looking for a way to add the spinning prop effect in a still.

Glad I could help (or at least point you in a good direction), Ed... Yeah, Xtaz is a great guy! And knows his stuff, too. But the best part is, he (like many others here) shares what he's learned!

 

My sig line says it all!

[Ed Doyle]

After following some of the tips and suggested ideas posted by the fellas above I think the new prop spin is much improved. Thanks guys

That looks really nice there Ed, now onto the dogfight...

Hi Ed ... I am happy for you to have gotten to apply MUFOOF in your work ... if you have some doubt regarding the method, don't hesitate in writing me ...

This, the basic sense of the life is not?

Now THAT prop spin looks TASTY! I'll have to keep this thread linked for future use! Good going.

[Dhar]

Right ON! That prop looks dangerous, I wouldn't want my finger close to it

 

Nice job.

[Ed Doyle]

Thank you for your kind words. And to Xtaz thanks for the offer, I'll certainly keep that in Mind.

Now I better finish that Corsair.
