If possible.... I've got my idea fleshed out, just not had time to put it down on paper....

Sure, we wait at least for HS. And others is somebody voice in.

Perhaps you could give a sneak peek at the next subject, so that some people can start thinking about the next challenge and build assets... (understand: keep me busy as I need an excuse to be in my underground office because it is scarringly hot outside).

Yes, I heard about the heat wave over there in Europe. Sounds pretty miserable, especially as a lot of you don't have air conditioners (especially those farther north).
Have a question? Send me a PM! || I have a Patreon page up for REKT now! || People talking in IRC over the past two hours:

Indeed, no AC in the office, no AC at home.
The only hope is the car... but normally (i.e. not in winter and when dry weather and when not too lazy) I bike to work.

Argh, yeah, it's not quite as bad here as further south, but it's still hot.

Last night I drove home at 12:30am.... With the roof down on the car

Hehehe, nothing more sinister than 3 different lights either side of each engine 'fin'.... So 18 all together.

6 of them are volumetric point lights, that gives the spherical element of the light.
6 of them are quadratic spot lights with a spread of 87.5 degrees, so it'll spread out to the sides.
6 of them are also quadratic spot lights, pretty much the same as the previous ones but with a 45 degree angle.

Here's a view of the bottom so you can see it better (and those nice hefty railguns) I've not lit up the smaller ones yet, but I'll get to that....
So, I tried something similar. Not as good as yours, though. Probably I should increase the power of the local light and reduce the directional ones?
Just for information: which model of lighting/atmosphere are you using?

A propos, I have always an issue because I would like "glowing things" but without "ambiant light" (outer space). And glow is ambiant. You would not have a solution for this, by chance? That would allow really long luminous trails, would be cool.

And by chance, I got a nice effect on the wings, however

That ship looks pretty damn awesome. I've pasted some details on the lights below..... Powers and the length of the ship I was using them on(within Vue) so you can fiddle with them by knowing the relative sizes:

Ship length 2.563 Km

Point lights - power of 1400
Volumetric lighting enabled, intensity of 0.1, maximum flare intensity and lots of random streaks.

45 degree spotlights - power of 400, spread of 45 degrees.
Volumetric lighting enabled, intesity of 1, 50% flare intensity, no streaks.

87.5 degree spotlights - same as above but with an 87.5 degree spread.

Atmosphere model standard, lighting model standard.

-----

I did some twiddling with spotlights using a 2.5 degree spread that might be good for exhaust trails.... The only grip being they spread out, but if you added a decent amount of falloff, that could work. Annoyingly, directional lights can't be quadratic, otherwise they'd be perfect!

I've also considered doing a similar thing, but having lots of different lower intensity lights with different spreads, that might work well... Hopefully I can experiment over the weekend

Ah yeah, that idea worked pretty well. There's a point light in there and a spotlight with a 2.5 degree angle buried inside a torus. That'd work for exhausts

I was partway though a story but it was a bit boring, so I've gone a different route. Just doing a decent quality render now then I'll get my stuff posted

Looking forward...

I am a bit silent lately as I had to spent 2 weeks at my father’s place in emergency (he is doing well again but it was touchy for several days....) and I am now traveling on holidays. I will try your tricks for engine glows when I am back where my computer is and report back!

I'm glad to hear your father's doing well.... Looking forward to see what you can come up with on the engine glows

So, back home I got a shot at your idea.
I wanted to have something that is brighter at a certain distance of the exhaust, and then disappear.

The result (using 36 spotlights and 4 point lights per exhaust) is given below. The point lights allow the exhaust to actually lighten the other objects, In this scene, there is no sunlight nor any normal lighting via ambiant, it is only lightened by the exhausts themselves.
Each spotlight (spread 7°, softness 10°) has a volumetric element with quadratic decay, a variable colour with cutoff at 20m with the last part of the colors palette being black (so blue-white-yellow-orange-black), and "smoke/dust" in the beam using a pre-set function.

Btw: I found a way to cancel ambiant lighting but still use it for luminous objects - you may know it, but for me, this is a major discovery as it finally allow deep-space scenes with luminous objects: In the atmosphere editor, just put under "light" the bar at 100% sunlight. You can then still increase the ambiant light in the post-processing, but it impacts then only luminous objects, not the whole scene!
In the scene above, there is no ambiant lighting, BUT the cockpits and greyish shapes on the ship both have luminous elements (and obviously there are some stars...).

Daaaaaaamn, they look amazing I wonder how the dust effect'd do when animated..... Probably expensive to render, but it'd look awesome when the ship's moving!

I must twiddle with the atmosphere settings more. I currently roll with 90% of the light coming from the sun already, I find it gives me a decent effect.
