I wouldn’t be able to say for sure since I’ve never done fire before but looking at the comments it looks like they used the particle system inside cinema 4d. I’m thinking the used a 3d point tracker for the shots. Then took the points around the actors to emit the fire particles.
There’s an example fire that come with cinema 4d using pyroCluster. Doesn’t look the same as the video but could be a starting point.
One of the people invloved in it is Luxx, Tim Clapham, who has bunch of stuff on his site to learn particles https://www.helloluxx.com/ There may be something there to figure it out.
Hope that helps and if you figure it I’d be interested in knowing as well.

I would suggest using Mocha for what your trying to do. It comes bundled with after effects and is a good planar tracking program.
You could try the tracker in After Effects but I usually find Mocha easier to use for a lot of stuff.

Just a quick idea, you might be able to do it AE if you have a precomp with a bunch of circles filling up the comp. Then you could use a larger circle on top of it and use it as an alpha mate for the shapes underneath. That would give you the shape cut out of the smaller circles underneath.
I’m sure there’s a better way then that though probably using some expression but I’m not sure what.
Another idea just came to me you could use the Cocoe Battalion expression to fill an object based on mask shape. I used it to trace and outline of circle target for an animation I did.

In C4D you could just use a cloner set to an object mode then just clone a bunch of smaller objects into the shaper of the larger one. There’s few different options like volume or vertex you can use to get it filled the way you want.

I’m not fully sure what your problem is based on how you described it but it you want the texture to have full color then you need to set it in the colour tab properties. If you want it just in the reflection then you need to click into fresnel properties right there in the reflection properties and change the gradient colors.
Hope that helps

Taking a quick guess at it here I would say you just need to create a switch to tell you light blink when to begin. So one light would start taking the frame input to start blinking at frame 2 the next of frame 6 and so on.
I’m working on this right now for robertleger.net Xpresso Tasks(another great place to learn Xpresso) where I’m simply automating the strength values of effectors to the run over time without needing key frames. I simply offset the start value until the it hits the frame set in the user data. Then the frame value is let though and increments the value.
I would have to play around with your setup to be sure for your case though.
Hope this helps.

This link should send you to the c4d to maya(I used it the other way) guide I uploaded to google docs. It list some of the shortcuts and some other useful reference information. It’s not as complete as the one in cinema though.
It’s a pdf and I’ve printed it before it looks fine unless you want it at a huge size. The one from the real website seems to be dead link if you want to print.

No problem glad I could help

I actually just created this effect on a model I made a little while ago. https://g2b.deviantart.com/art/3D-NutCracker-209524402
All I had to do was use a boole which is in objects > modeling menu and subtract one object(helix spline) from the cone part. If you need more help I can send you the drill part of my model so you can see how I did it but the effect is fairly straight forward once you have it lined up right.
Good luck making the model.

I happen to stumbled upon this apparently 2 years late but I needed the answer and after paying around for a bit and googleing I figured It out. I thought it would be nice to post the answer for future reference.
My solution was to use a cube setup as film roll straight. Then use a spline warp(mograph) to warp it with a spline. I originally tried like like Paul Maynard but texture would not come out right unless it was straight. Which is ok but chances our you need the film to roll and bank. But this way with cube projection on UVW Mapping and warping the whole object(I think) there is no issue of distortions on the texture.
Below is what I made to figure it out. There’s a bunch of tuts now for spline warp
