Neuron-Fire // looking for files that you made for me ;(

@Dr-Sassi
 I'll check out this file tomorrow, a big THANK you!-fyi, I attached a jpg of what I hope to achieve., Best, Craig -
Hi Craig,
Thanks a lot for the sketch; that helps. Why not do it with options we did not have eight years ago integrated into the way we now have?
Please have a look here:
Press play while the Vertex tag is selected to get a first impression.
Enjoy

@Dr-Sassi Dr. Sassi, hi, this solution is awesome!!!-thank you-will I be able to replicate this with a polygon model ? that is what I'd prefer; is there a tutorial on Cineversity that I can learn how to do this w/o burdening you?-Craig
-
Hi Craig,
First of all, you do not burden me.
The object has to have a high-resolution mesh, as the Vertex mesh works with points/vertices. The Matrix is used in the Vertex Map Tag as a Point source. The Point source can be adjusted in radius/diameter. This provides the light spot.
The key is that the Decay layer will create the "charge trail" of the Neurons; it has a sweet spot in the settings. I got that idea by searching images of neurons and how they "communicate". So the charge comes and leaves slowly, hence the "trail".
Perhaps start with a simple plane object and a spline to explore it. My model used the Splines as well as a base to create the shape, meaning that changing the Spline will shape the "body" but also direct the "light" with it so things stay in sync. Any polygon object, as defined above, will do if that adjustment is unnecessary.
Please let me know if there are any questions. I'm happy to look into them.
Cheers

@Dr-Sassi Please see my attached file-my apologizes, I went from using Arnold a lot, to Redshift, never used all of the new C4D materials, pbr, etc, I didnt realize that you are using RS, which I have-I didnt realize that the lights were RS, which I am very familiar with ( DUH!!) lately I'm trying to learn Houdini ( what do u think of it? ) so I applied a base material first, here, light material second-this solution is really cool-I have never used RS for animation, anything that I should be on the lookout for?, flickering issues? anyway, unless I can think of anything else, you are the ultimate problem solver; no wonder why you are "the Doctorneuron-Sassi.c4d "-stay safe, Craig

Hi Craig,
Could you please check the file? It might be too large for the forum. Do you have Dropbox, Google, Apple, Adobe, or Wetransfer cloud options (I do not touch others, sorry)
Yes, Doctor for Neuron, when Neuron means life and Animation means bring to life, my dissertation was about Computer Simulation, or simply put about animation/film. It is not an MD, just to be clear
Houdini is a very specialized app, with reminds me more of working like in NUKE, Fusion, or back in the days, Shake when I take a compositing analogy, as it feels more like a spatial/animation compositor.
However, whether I think it or not ;-), software needs to fit the thinking pattern and logic of the artist. Otherwise, it is a painful relationship. But when it fits, even steep learning curves are fun.
I will look at your file when I get it—looking forward to it. If you need an upload link, my Dropbox has some space left.
Cheers

i have a Dropbox, can please send me a link? I used edge to spline for my path, for the lights; when I said "Dr." I meant that you are all knowing, omniscient when it comes to C4d, a compliment
-
Hi Craig,
If you have a Dropbox, then I don't understand.
Anyway, I will leave this link for a few hours here. Please only the needed parts, as mentioned, that is my private Dropbox, and it is small.
--link-removed---All the best

Hi Craig,
Can I share the link here or what is your preferred option to get it back?
Cheers

Hi Dr. Sassi. I hope that you are well. I have a question please, about 17 days ago, you provided for me a great solution, to lights traveling
over/through a neuron. I was hoping to experiment with different color combinations, with RS of the body of the neuron. I noticed, that when I use a different material color, and Im sure to properly use the vertex attribute node, the emission/lights are not visible in the viewport, only when I render in the viewport. . Also, the "lights" are not moving when I render to picture viewer. I did this just to experiment with a render. Can you please tell me why this is? also, the way to control speed of light movement, I change the offset in the matrix?, thank you, Craig -
Hi Craig,
I have rendered the file from above today since you asked. It works.
When you say you have changed something, How can I know what? Could you please copy and paste the material into a new scene and share it so I can look at it?
Cheers
-
neuron-lights-for-DS.c4d I bought some neat materials, have been too busy to experiment, but perhaps you can show me the way for the furure. I'd love to use your elegant solution for a mor interesting texture, thanks so much-CZ
-
Hi Craig,
Thanks for the files.
To see any effect, the Emission> Weight needs to be greater than zero.
I got all four materials working that way.
All the best
-
thanks, but I don 't see it in the render view, as opposed to the other material which I do, is it possible to see it in the render view when i hit play?
-
Hi Craig,
Below are all four materials set up with an animated Vertex map. I rendered it, and all looks fine to me.

Render View, Picture Viewer:
Picture Viewer takes the scene as set up, including Render Settings, and goes to work. Once started, any change will be ignored; it just works on the job it was given.
RS Render View
The Clapper board Icon works the same as the Picture Viewer.
The Play icon right-sided from the Clapper board icon will take updated information, but only when capacity allows it. The more rendered heavy a scene, the less likely it moves toward "real-time".
Editor View> Redshift IPR
Perhaps fast, depending on the size.Anyway, anything I will say might not match your experience, except you have the same setup, screens, and apps running at the time of comparison. This goes into hardware, which I try to avoid at all costs. Not my place, as I think the variables are way too big. Things change constantly on top of that. So yesterday's knowledge is perhaps outdated with the latest update—nothing I like to invest time into. Thanks for understanding
Cheers

@channel-blame [link text](NEURON-glow-does-not-work.c4d link url)-hi Dr.Sassi, how are you?-I am in a bit of a panic ;(-I tried to adapt your brilliant solution here to a new texture, but I can not get it too work. Is my attachment here? if not please tell me how to attach. My solution is not working, perhaps you can provide a solution for me. Please let me know, Craig

ok sorry and thank you, is it possible? my new problem that is to solve?

Hi Craig,
Posting in the wrong thread is not a problem; I only mentioned it so you know I moved it. Otherwise, it will be hard to read along for others.
Here is your file:
https://stcineversityprod02.blob.core.windows.net/$web/Cineversity_Forum_Support/2023_PROJECTS_DRS/20230810_CV4_2023_drs_23_RSsv_33.c4d.zipPlease let me know if that works; I have tested it on several versions, just in case.
I have increased the Mesh a bit, as the RS Tag will not have its "Virtual Points" being used for the Vertex Map, and without increasing the Mesh, the "Vertex Map Resolution" is too blocky.
Please also ensure that the information used by other objects, etc., is above the one that needs it. Top to bottom is the flow of information, and yes, with Priorities, Information runs more complex, but inside the Object manager, ensure you have all the "stuff" in a flow.
My best wishes for your project.

Thank you Dr. Sassi, but I did send to you a "neuron" with my texture that I couldnt get to work; this file I already received, thx. If you did not get it what is the best way to share with you? thx, Craig
-
Hi Craig,
This is the file in your post from above that you quoted; hence I took a look and tested it for an hour, and as you can see, I have changed it a lot.
I take Dropbox, Apple, Adobe, Google, Wetransfer could services.
All the best
