how to smoothly fade out an object? Tweet

[miohn]

Hi,

cannot get that to work in octane!

I want an object to smoothly dissapear/fade out in about 20 frames.

I tried c4d "visibility" tag, octane tag "generell visibility" and also animating the flow-value of a "mix material"
Nothing works!
All the time I only get a harsh weird blending and no smooth transition!

Beside doing it in post - is there a way to do this in octane?

regards
Mike

Interesting post! Is it what you want?

hmmm - in your example it works alike it should.

I linked that up with a slider via xpresso and I got very strange results.
So there must be an error in my xpresso-setup (range mapper or somewhere else)

thanks

Just make a user data slider and set as percentage, and pipe that into the visibility port of the object tag. Works like a champ.

well, that was exactely what I did.
Still investigating whats wrong here, but good to know, that it should work.

thanks
Mike

You did mention you had a range mapper in between, correct? You don't need one if you match the slider data type to what the tag expects. That is one less element for Cinema to process, and these things can all add up.

Hi, Ive got the same issue.

Transparency Objects Tag for transisition / fade is not precise with the octane slider; neither the visibility tag of cinema 4d.

I have no glue how to create a "customized percentage slider" – I simply think that the fading should work smoothly, without having a harsh tansition (especially in the "last transition frames from x to y). Eg Example: Hiding a "covering" Object and revealing the inner object (placed within the outer object).

Your simple example with only diffuse texture applied onto the object works. But on a. it more complex objects containg textures/specular/bump mapping it simply does not work.

How do I get fix this?

Thanks for reply, its urgent within the project.

Best regards!

The best way to do this is to use compositing. Render the amount of dissolve frames that you need and comp in the app of your choice.
