Hey thanks for the response, I think I've isolated the problem. I've defined the art assets with new values for the different black holes:

<ArtDefine>

<InternalName>SuperBlackHole1Art</InternalName>

<Radius>23</Radius>

<ModelFile>Gfx/Models/MiscAssets/Meshes/Blackhole_Mesh_01.sdf</ModelFile>

<EffectFile>gfx/fx/sm4/compiled/ModelNode4.fxo</EffectFile>

<SurfaceTextureFile>gfx/PlanetGfx/BlackHole.dds</SurfaceTextureFile>

<InnerHaloBias>0</InnerHaloBias>

<InnerHaloColor>

<Red>0</Red>

<Green>0</Green>

<Blue>0</Blue>

<Alpha>0</Alpha>

</InnerHaloColor>

<StrategicIcon>LargeBlackHole</StrategicIcon>

<StrategicIconColorDefine>UIDefault</StrategicIconColorDefine>

<ParticleEffectScript>BlackHoleJetEffect</ParticleEffectScript>

<UnderFogParticleEffectScript>SuperBlackHole1DiskEffect</UnderFogParticleEffectScript>

</ArtDefine>

So I'm pretty sure I need to edit the BlackholeDiskEffect.xml files in Particle Script Defs folder. So... now I need help and to work out what all these other values in the particle emitters mean... bit daunting haha

As for showing you the money, there seems to be a fully functioning black hole in my bank account at the moment so I don't think that's possible   

Edit: I've played around with the particle values, but nothing seems to be taking effect, I'm definitely missing something 

Thanks,

I've tried that but still no joy. When I change the name of the ParticleScriptDef the particle animation disappears, it only seems to work with the two references "BlackHoleDiskEffect" and "LargeBlackHoleDiskEffect". I've also tried changing the ScaleMod on a black hole that I can see is working, but changing that value isn't doing anything   

Hit another roadblock. Started a new post because I'm now further into the rabbit hole and asking something completely different now...
