10.21TUTORIAL: Dynamic Modelling in C4D Using MoGraph
Does your client want “that light grid look from all of the music videos a little while back”? FINE…but you need to scroll a bunch of text through it…which means you need to be able to switch in new text on the fly. PROBLEM…until now. You would have to fake the lights using some sort of animated texture map. That’s not a bad solution until you need to get CLOSE to the lights and then they’ll end up looking like crap. Using the Volume Effector from C4D’s MoGraph module you can model dynamically, leaving your text in a procedural generator (Text Object), ready for changes.
In the first part of this tutorial we’ll go through the theory and setup the basic MoGraph model and get it running. In part two, we’ll work on actually modeling the lights and the rig to get a good-looking final model.
STEP 01: The Bulb
Create a simple sphere object and make it very small. We’ll also reduce the number of segments to something low so we won’t slow down our viewport.
STEP 02: The Rig Holding the Light
Create three cylinder objects and offset them behind our sphere.
STEP 03: Grouping the Objects Properly
Then add the three cylinder objects into the group. (This is important so that our axis center for the group remains at the sphere’s center.)
STEP 04: Matrix Object
Create a matrix object from the mograph menu. (You could just use a cloner object, but we are going to be linking multiple cloner objects from this matrix object, so if we need to change any of the characteristics of the matrix object, it will update in both of our cloner objects.)
STEP 05: Cloner Object
With our bulb group selected, create a cloner object while holding down option (this will make the new cloner object a parent of the bulb group). Under the cloner object’s attribute settings change the mode to object and drag the matrix object into the object dialog box.
NOTE: After creating the cloner object, I realized that my cylinders we too fat and short. I changed their settings a bit. (this is why procedural objects are great!)
STEP 06: Our Text
Create your normal text object with a text spline and an extrude nurbs. In the extrude nurbs settings change the movement to 0m. We just want plain flat text.
STEP 07: “Lights On”
Duplicate our cloner object and then delete all of the cylinders. Also make the radius of the sphere smaller than that of our bulbs. (These spheres will be the bright spot inside the bulbs that are “on”)
STEP 08: Volume Effector
With our new cloner still selected, create a new volume effector from the Mograph menu. In it’s settings, drag the text’s extrude nurbs object into the volume object dialog box. At the bottom of the attribute menu check the Visibility checkbox to on. (This will make it so our “on” bulbs only show up where the text intersects with our matrix objects (kind of like a boolean object, all of the other “on” bulbs will be hidden.)
STEP 09: Some simple textures
First we’ll make a transparent texture for the outer bulbs (use a Fresnel shader for more realistic transparency. Then make a luminescent texture for our “on” lights.
Apply them to our objects and hit render. We’re done. We now have a lighting grid that we can still edit whatever text is being illuminated.
In part two, we’ll work on giving the bulbs, lights, and rack models a little more detail to add some style. I hope you’ll check it out.

Great tutorial and good explanation, i were looking for a tutorial about create a Disco Floor of 70′s, I wonder if you know how to creat that fx with the lights on the floor to the rythim, I mean, that the lights follow a sequence like the old machines for that fx. Thank you for hear me anyway.

Hello Sandro,
There are two ways I would go about making a disco floor in C4D. The first would be to use lights in a cloner object. The second would be to use planes in a cloner object with a mographer color shader in the luminence channel of a texture. Both would involve using a sound effector to time the lights to the music.
For the first answer, there is a great tip from Tim Clapham over at helloluxx, another great C4D blog.
http://www.helloluxx.com/cinema4d-mograph/randomness-with-lights/
I’ll look around for a tutorial on the second answer. If I can’t find one, maybe I’ll write it!
Thanks for reading!

Hi
Great tutorial! I’m a C4D newbie. Everything I’ve done following your tutorial is working fine…except I can’t get the letters to light up in yellow. The clear lightbulbs work, but when I hit render I see clear bulbs with the white text behind. I’ve re-done the volume effector, but it still doesn’ t work. Any ideas on what I’m doing wrong? Any help would be appreciated!
Thanks,
Andrea

Thank you so much,i am learning in cinema 4d.

Hi,
I’ve been having the same trouble as Andrea, and I wonder, is it just that the Extrude Nurb has to have the lower dot marked red so it’s hidden? Also, having trouble with the bulb material, the Fresnel doesn’t look nice like in your example. Just started using C4D, and am having a blast, thanks!

Nobody wants to learn..hahahaha they already wanna the maded project..and just replace something to manke money. kkkkkkkkkkkkkk Tanks for share knowledge.

I’m having the same problem as Andrea. The words won’t light up. Does anyone have any idea what’s wrong?
Thanks

I am having the same issue as Andrea.

Thanks for a great tutorial. The answer to Andrea’s question is reference step #3 again.
Step 3 says to make sure that the original sphere created in step#1 has X and Z coordinates that are = 0. So in turn when you create your text, it will intersect at 0 with the cloned spheres.
