[1.5.1] Engine Lighting (1.5.1) Little Config Update (13 October)

Tyko · January 4, 2019

was playing around with Engine Lighting and noted that the light from the engines will pass through intervening parts of the ship to strike other parts.

For example, I have a wide lower stage, a narrow middle and then it widens again. Light will shine on the widening area as if the lower wide area didn't exist.

Is it a limitation of the game engine that prevents parts of a craft from casting shadows on other parts of the same craft?

possibly. @MOARdV was able to refresh this mod not to light everything but don't know if it creates shadows

What I did was to configure the light as a spotlight so that it only casts light away from the vessel. I don't think that's what you would want for engine lights. The Unity Light object includes controls to turn on shadow casting for a light, but I have never experimented with those controls, so I don't know if KSP allows them to work. If shadow casting does work, I imagine that it would get fairly expensive to generate shadows for a multi-engine stage like a Falcon-9 first stage. But it'd be worth a try, perhaps.

As mentioned by @Gordon Dry on 2018 Nov 12 and @Moofrog on 2018 Nov 13, there is a typo and a few MM needed changes in EngineLighting version 1.5.1 in both manual and CKAN installs.

I've emailed these to the maintainer @tajampi, but until a new version is out, here's the needed changes.

Just to clarify: the line 74 patch shouldn't actually remove the "@", and line 357 also has a "@" that should remain.

It's more that the lighting in the game isn't the same as in real life. I've been a shuttle night launch as well and it is so bright it's like watching a sunrise, but it doesn't actually light up the shuttle itself the same way the game lights the spacecraft with point lights. The shuttle is pretty evenly lit because all of the light on it is coming from reflections off the ground and diffused light from the exhaust.

I observe this photo, the shuttle is pretty evenly lit.

I propose an approximation to create the lighting effect from exhaust.

Another motivation is that current Engine Lighting mode is to add point light source per engine.

When the number of engines is high, the frame rate is low.

My proposed idea:

1 Add only one light source for all engines, instead of one point light source per engine

This can prevent lag by adding too many light sources when there are many engines

2 This added light source should have a virtual position which can be attached below the center of thrust.

And this added light source has both ambient light source and point light source properties.

Entire scene, which includes ground and the rocket, is lit by the light source with decline according to distance square, like point light source.

However, the lit pixels disregard the cosine effect between incident direction and surface normal direction, like an ambient light source.

Rocket Witch · April 13, 2020

Is it possible to specify a light colour based on the mode an engine is in?

Also, is it a known issue that engines don't produce light when activated via RMB menu instead of staging?

(Asking here because this is the version of EL I'm using.)
