The problem is with your sample distance in the visible light settings, you currently have it set to 25cm ( possibly default ) but your engine is about 200meters long and the jet thing twice as long, so set your sample distance to 5000 cm and it will work.

 

My previous method simply made the model small enough to work with the 25cm sample distance.

I tried the Sample Distance (which was indeed at 25cm as default) and put it at 5000...but still doesn't work. Only the Scale Project works (although when I look at the Project Settings I see it as in cm, not km). So I setup the Scale Project to make 1cm as 0.1 (so 10% from the scale it is now) and now it works.

Seems to be a scale thing, your project scale is huge, dont think its anything to do with camera focal lengths.

If you go to scale project and scale kilometres to centimetres you get a result like the grab below.

Centre of your object is way off too, was tricky trying to find it and navigate the scene

But when I go to the project settings I see the project scale in centimeters, not kilometers!

I have a scene where I use two visible lights to make a jet flame. 

The problem I have is that when I enter the camera and render (Physical render) I see only a very small portion of that visible light but when I exit the camera I can see all just fine when I render (the same Physical render). Camera is now at 135 mm focal length...if I change it to 50 mm then I can see the render (in the first part of the animation, not the last part). If I change it to 80 mm I can see the beginning of the flame and the end (in the first part of the animation, not the last part). At 135mm I can see only the beginning a little.

What could be the issue?

The scene is attached here. Thank you.

How to make a rocket engine exhaust look like in the image below?

Now I am using Black body as Color for Fire Shader...and I see there is the Manual mode...I tried it but I don't get the result I want. 

Any idea? Thank you.

Not exactly what you're looking for, I know, but here's a tutorial for a free plugin for making ocean waves:

 

I don't think you can simulate a boat splashing around in it, but you probably could fake it with some displacement, particles, etc.

Actually I used this Hot4D to simulate ocean but I was looking into Realwave as alternative.
For a boat, I also used Inifnite Ocean https://www.c4depot.com/c4d-plugins/infinite-ocean/ which does simulate a boat on an ocean but not extremely realistic (unless your scene doesn't show the boat very close).

Where I can find tutorials to help me make an ocean in Cinema 4D using the Realflow/Realwave plugin (directly in Cinema 4D)? Later on I want to add a ship to interact with that ocean.

I have Cinema 4D R19 and Realflow 2.5 (with plugins in Cinema 4D).

I found some tutorials for working in Realflow but I wondered about working with Realflow plugin directly in Cinema 4D. The Internet seem short on these...

Thank you.
