Hi Ahmet & folks

Is it possible in some way to animate the "build in" noise inside the Volume object? Becouse i cant get this done, this is just not responding no matter what i'm doing.
Is it lack of functionality? If it will be possible it will be super useful to create some clouds movement.

Thanks.

OK - Found a way to make it work:
Keyframe on the "Movement" field + some animation speed.
For some reason this is not the standard C4D way to animate noise but it works.

I guess this topic now became a feature request.

Video attached.

Thank you for sharing!

I don't think it's the Movement field that is actually doing the animation evolution here, it's still the Animation Speed parameter.
Adding the keyframe to the Movement parameter means Octane can see that the noise is updating and refreshes it every frame.
So you could add keys to any of the parameters inside the noise and it would trick Octane into updating the animation.

Man! Looks awesome.

I'm hoping that this fractal type effect (displacements, fluids etc.) is similar to what Jim Star has been working on for Maya, for the last 3 months.

Cheers for sharing.

I am trying the same thing here and it looks like only "Animation Speed" is doing any changing, "Movement" and "Speed" have 0 effect.

Am I missing something? or this isn't supported in 3.03.4 R3?

Thanks,

Sandi

Guys,

You are forgetting that how plugin works and doesn't read a few posts. It's not straigth-forward send all data on every frames. It has a state-engine to detect the just updated parts of geometry/material/etc...
So we have a update detection engine and it needs to catch some messages. "Animation speed/etc.." is not enough to produce this message. You need to add keyframe to trigger updates.

I am not forgeting anything, the part about keyframes is clear from the begining as I wrote in the post "I am trying the same thing here".

What I noticed is that even if you keyframe "Movement" or "Speed" attribute, there is no change in the render. This is not limited to vdb in this case, it also behaves like this in texture, example attached: If you render with c4d render the noise is changing in octane not.

Thus my question, is this supported in latest version. Thats all...

Just setting a keyframe at same value is not enough. Key values should be different. See picture.

Ok, I think I need to be clearer - "Movement" and "Speed" attributes in noise are not translated into rendering.
Here is an updated file (added small change in keyframes): Here is the rendered result, left c4d, right octane: If this is supported I am clearly doing something wrong, please let me know what it is, thanks.
