Material Transition

Hi,

I have been following a tutorial for cinema 4D. It creates a transition in the material.
Octane render materials dont' have the alpha option like the C4D materials have....How can I recreate the effect?
Also, when I use the Cinema 4D materials I manage to get the same animation but only if I use the intergrated rendering engine in C4D... octane does not render the material the same way as on the C4D viewport...why is that?

Here is the link to the video with the transition I am trying to achieve:


I've added some screen shots...why is octane render behaving like this??? What I am missing here?

Hope anyone can help!

Thanks!

Stefano.

I'm not sure what you mean exactly with that DOES NOT support ALPHA. It support ALPHA. You can use opacity channel for that.
1- Use mix materials
2- Use material stacking. It came to plugin on latest builds.

It's possible to do that with a MixMaterial and driven parameter by xpresso.

The solution with C4D noise of this tutorial doesn't work well because it uses 3D projection of gradient.
As the C4D noises are baked on the fly by the Octane plugin, it will not work well with a driven C4D noise in 3D space like this "out of the box".

I'm not an expert in xpresso but here are two samples you may adapt to the tutorial.
One full Octane with MixMaterial and noise projection driven by xpresso and the other with a C4D gradient driven by xpresso.

The C4D one will not work well in Live viewer (you have to stop animation to see the baked gradient) but will render fine in Picture viewer. You have to use the very last version of the plugin to test it.

I hope you'll find this usefull... :)
