Thanks,
What you sent worked!

The only issue now is that we are rendering this out with an alpha channel, so I believe the issue is that C4D does not recognize the alpha because it is generated at the level of the material. So we are seeing all the particles when rendering with an alpha channel, dark particles mixed with the bright ones. We can work around this by using the Extract plugin in After Effects, but I am wondering if there is a way to get the alpha to respect the particles that are not being hidden by the noise in the material.

Thank you!

Hi Dr Sassi,

I have followed this tutorial (https://www.youtube.com/watch?v=6ySJGioTsis&t=1s)
showing how to get an object to flicker using fracture, and a Plain effector driven by a random animated noise. I have this working, but I am trying to use the fracture object as a particle in the C4D particle system via the RedShift tag. Currently, in the attached project, all the particles turn on and off together. Is there a way to have them go on and off independently of one another to get a flickering effect?

Thank you again for the help and the material!

The new material seems to work. Do you know why this is? I still do not understand why the reflection showed very clearly when doing the first pass of the render, but then finishing it, it mostly completely disappeared.

Don't know why the textures did not go through. Here they are.
The black glass material is an experiment; we are trying different materials to see if any reflect better than others.

Thanks for the help!
Mark

Dear Dr Sasi

We are trying to reflect particles from an emitter off of the "Know Thyself" text in the linked project.

We can see the reflection clearly in the Redshift Render window, but when outputting the animation, we do see the reflection at the beginning of the render as it is calculating the Irradiance Point Cloud, but when it does the final pass, these reflections are greatly dimmed or completely gone.

What setting will need to be changed in order to keep the reflections visible?

Thank you, this helped!

Hi Dr Sassi

Please see the attached file with a stripped-down C4d project, and note in the attached images that a patch of the ground cover disappears between frames 880 and 881. Something similar also happens between frames 896 and 897 in a different spot. We have eliminated all animation, and the settings seem otherwise identical between the 2 frames.

Please advise.

Thank you,

Thank you for the additional info. I will take a look at what you sent when I have a chance. Don't know what you mean by a "sketch"?

Also, I am not a student, I work for a nonprofit creating materials to support their educational program.

Thank you I will give that a try!
