Can't seem to replace rocket launcher explosion particle. Please Help!

[Oblivion2500]

I created a new particle for the rocket launcher explosion. I replaced it in code and I when I tried it out. As soon the rocket hit impact, there is no explosion at all, and I still get hurt by the radius and damage but everything else is invisible.
Here is the code for the Weapon and the Projectile:

UTWeap_WebSplitter:

class UTWeap_WebSplitter extends UTWeap_RocketLauncher;

simulated function SetSkin(Material NewMaterial)
{
	Super.SetSkin(NewMaterial);
	Mesh.SetMaterial(0, Material'WP_Beta_Project_Obliteration.Materials.M_WP_WebSplitter');
}

defaultproperties
{
	Begin Object Name=FirstPersonMesh
		SkeletalMesh=SkeletalMesh'WP_RocketLauncher.Mesh.SK_WP_RocketLauncher_1P'
		PhysicsAsset=None
		AnimTreeTemplate=AnimTree'WP_RocketLauncher.Anims.AT_WP_RocketLauncher_1P_Base'
		AnimSets(0)=AnimSet'WP_RocketLauncher.Anims.K_WP_RocketLauncher_1P_Base'
		Translation=(X=0,Y=0,Z=0)
		Rotation=(Yaw=0)
		scale=1.0
		FOV=60.0
		Materials(0)=Material'WP_Beta_Project_Obliteration.Materials.M_WP_WebSplitter'
	End Object

	WeaponProjectiles(0)=class'Project_Obliteration_Weapons.UTProj_WebSplitter'
	WeaponProjectiles(1)=class'Project_Obliteration_Weapons.UTProj_WebSplitter'

	AttachmentClass=class'Project_Obliteration_Weapons.UTAttachment_WebSplitter'

	// Pickup staticmesh
	Begin Object Name=PickupMesh
		SkeletalMesh=SkeletalMesh'WP_RocketLauncher.Mesh.SK_WP_RocketLauncher_3P'
		Materials(0)=Material'WP_Beta_Project_Obliteration.Materials.M_WP_WebSplitter'
	End Object

	AmmoCount=5
	LockerAmmoCount=10
	MaxAmmoCount=18
	
	ItemName="Web Splitter"
    PickupMessage="Web Splitter"
}

UTProj_WebSplitter:

class UTProj_WebSplitter extends UTProj_Rocket;

defaultproperties
{
	ProjFlightTemplate=ParticleSystem'WP_RocketLauncher.Effects.P_WP_RocketLauncher_RocketTrail'
	ProjExplosionTemplate=ParticleSystem'WP_Beta_Project_Obliteration.Particles.P_WP_RocketExplosion'
	ExplosionDecal=MaterialInstanceTimeVarying'WP_RocketLauncher.Decals.MITV_WP_RocketLauncher_Impact_Decal01'
	DecalWidth=256.0
	DecalHeight=256.0
	speed=1350.0
	MaxSpeed=1350.0
	Damage=160.0
	DamageRadius=440.0
	MomentumTransfer=85000
	MyDamageType=class'UTDmgType_Rocket'
	LifeSpan=8.0
	AmbientSound=SoundCue'A_Weapon_RocketLauncher.Cue.A_Weapon_RL_Travel_Cue'
	ExplosionSound=SoundCue'A_Weapon_RocketLauncher.Cue.A_Weapon_RL_Impact_Cue'
	RotationRate=(Roll=50000)
	DesiredRotation=(Roll=30000)
	bCollideWorld=true
	CheckRadius=84.0
	bCheckProjectileLight=true
	ProjectileLightClass=class'UTGame.UTRocketLight'
	ExplosionLightClass=class'UTGame.UTRocketExplosionLight'

	bWaitForEffects=true
	bAttachExplosionToVehicles=false
	bAttachExplosionToPawns=false
}

I'm not a coder but...

Sometimes problem might not be in the code but in the way game effects are set up.

1) In material editor, under ''Usage'' make sure you have ''bUsedWithParticleSprites'', ''bUsedWithBeamTrails'', ''bUsedWithParticleSubUV'' checked.

2) In material tree, you should have ''VertexColor'' expression assigned somewhere, f.e. connected with the rest of setup via ''Multiply'' expression.

3) In Cascade, under emitter, ''Initial Color" or ''Color Over Life'' module should be added. Without these, particles won't show up in realtime. (it was so annoying, till i found a solution ).

Finally a reply from someone. I will try that and report back to you. Thanks.
