The maxSteps amount is still hardcoded inside the big custom node within the matfunc: RaymarchDistancefield. there is quite at the beginning of the while loop a lin you may change with caution: if( ++samples > 512 )
512 is the maximun amount of steps before cutting off. but should be enough in general, otherwise one may look for making the nebula itself more performant (e.g. with the blur-feature)
I am not quite sure what yoh mean about dissapearing of the nebula or the digital likelol. can yoh explain this a bit more?
when lowering the EnvironmentOcclusion the nebula will dissapear because it fades with the background. it’s required for a smooth fade of an object leaving the nebula away from the camera.
the nebula itself is a persistant actor in the level. when too far away i recommend to set the RenderSphere to be HiddenInGame to stop the rendering without need to destroy.
