[Boamere]

Going on about far, do you predict any issues?

[NathanKell]

To the best of my knowledge land launch from Baikonur (52d) is 13.5; equatorial to LEO would be 14.8. Unless there were recent upgrades?

NMB is right, obvs

Nazari (hotrockets dev) has been helping me with some particle stuff. So I've been working on some custom particle systems. Still a lot of tweaking to do though, since I'm new to this somewhat limited system.

[Stevincent]

oh wow that is sexy as hell!

If you could please put up a simple 123/ABC walkthrough of what you work out from implementing your own FX under the new particle system, that would be fantastic

[Nazari1382]

Those look good! I'm gonna write up something for how I was doing them in the hotrockets thread

Double awesome, when a single awesome isn't enough.

[Daemoria]

Wow, those flames look niiice, such a nice change from the bog-standard white/off yellow default flames. I eagerly await the particle fx tutorial.

[Percebob]

Quite impressed by those FX, (and by the rest of this sexy rocket of course) they match the look of it way more than the stock ones.

Off-topic : Are you the same stubbles that worked on a BSG Nexus mod ?

Hah! Yeppers

On that note, we're still working on it, but it's hard. NBC Universal closed all BSG mods out of ModDB and most of the team is gone. It's basically me making art and one scripter working on all of the mission/AI stuff.

Thanks for the feedback, all. I'll post some more shots later when I got the FX nailed down.

[Percebob]

Good luck on that then, still hoping for a new version of the mod. And always nice to have experienced, talented modders creating (cool) things for KSP.

Fairly happy with the RD171 engines. The smoke is going to take some tuning.

I should have the other engines finished up tomorrow I hope.

[CERVERUS]

I am so happy i see this Project still be WIP,please keep it up,how you can,all parts are amazing!

Thanks!

[Tyrador]

Oh dear lord, that is amazing! Squad should hire you! Imagine if these were stock parts...

Hmm. The engine bells look like they are on fire (as if fire is surrounding them). Is this an optical illusion?

Yeah they do!

[stubbles]

Haha yeah the placement of the ThrustTransform needs to drop a tad. Right now the particles size between like 0.8 and 1.3, so the larger particles are clipping the bell. It'll be fixed

[stubbles]

RD120 FX are done. The flame for the main engine here is going to get a tad larger to fill the bell a bit more, but otherwise it's done.

[Daemoria]

Holey Smokes Batman! Those are some nice exhaust flames. I just wish the heatmap extended to the engine fuselage section, to simulate some light from the flames hitting it.

[stubbles]

Running into a slight issue with the secondary particle system on the RD-120

When the fuel runs out, the smaller particle systems continue to emit particles until the engine is throttled to zero :'( Anyone have ideas on that by chance?

It's like the smaller system is tied ONLY to throttle control and ignores the fuel level.

Here's the scripting on the part:

// MODULE PARAMETERS
MODULE
{
	name = ModuleEnginesFX
	//engineID = rocketengine
	runningEffectName = engineSmoke
	directThrottleEffectName = engineFlame
	thrustVectorTransformName = thrustTransform
	exhaustDamage = True
	ignitionThreshold = 0.1
	minThrust = 0
	maxThrust = 550
	heatProduction = 200
	PROPELLANT
	{
		name = LiquidFuel
		ratio = 0.9
		DrawGauge = True
	}
	PROPELLANT
	{
		name = Oxidizer
		ratio = 1.1
	}
	atmosphereCurve
	{
	 key = 0 350
	 key = 1 304
	}
}

MODULE
{
	name = ModuleEnginesFX
	//engineID = rocketengine2
	//runningEffectName = engineSmoke
	directThrottleEffectName = engineFlame2
	thrustVectorTransformName = thrustTransform2
}

// HEAT ANIMATION
MODULE
{
	name = ModuleAnimateHeat
	ThermalAnim = EmissiveAnimation
}

EFFECTS
{
	engineFlame
	{
		AUDIO
		{
		channel = Ship
		clip = HorizonAeronautics/Sounds/sound_rocket_rd120
		volume = 0.0 0.0
		volume = 0.1 0.5
		volume = 0.5 1.0
		volume = 1.0 1.25
		pitch = 0.0 0.0
		pitch = 0.1 0.75
		pitch = 0.5 1.0
		loop = true
		}
		MODEL_MULTI_PARTICLE
		{
			modelName = HorizonAeronautics/FX/RD120Flame
			transformName = thrustTransform
			emission = 0.0 0.0
			emission = 0.1 0.5
			emission = 0.5 1.0
			emission = 1.0 1.25
			speed = 0.0 0.0
			speed = 0.1 0.5
			speed = 0.5 1.0
			speed = 1.0 1.25
		}
	}
	engineFlame2
	{
		MODEL_MULTI_PARTICLE
		{
			modelName = HorizonAeronautics/FX/RD120Flame2
			transformName = thrustTransform2
			emission = 0.0 0.0
			emission = 0.1 0.5
			emission = 0.5 1.0
			emission = 1.0 1.25
			speed = 0.0 0.5
			speed = 0.5 0.75
			speed = 1.0 1.25
		}
	}
}

I'm guessing it's because the second engine module is empty of all real engine functionality? I can try messing with that, splitting the thrust up between them.

Oh my God...this engine...awesome,you are a wizard stubbles!!!

I would agree with your logic, but there are plenty of engines out there with multiple rocket bells - there must be a way to overcome this besides splitting the thrust

[NoMrBond]

Try adding dependOnEngineState = True for rocketengine2, so

MODULE
{
	name = ModuleEnginesFX
	//engineID = rocketengine2
	//runningEffectName = engineSmoke
	directThrottleEffectName = engineFlame2
	thrustVectorTransformName = thrustTransform2
	dependOnEngineState = True
}

Although I have no idea if that particular snippent will apply in that module, although the original transform splitting idea worked so hopefully this will also

[stubbles]

Yeppers, splitting the thrust between the bells worked. Now the smaller RD-8 engines will stop spawning particles when the fuel runs out

Thanks for the help, all!
