RyanONeill1970 Posted December 1, 2018 Share Posted December 1, 2018 I have an arc camera attached and have removed the mousewheel zooming from it. Instead I've intercepted the mousewheel event and I'm trying to scale all of the particles via the parent mesh so that the scene stays the same, but the particles all zoom in / out. Before sps.setParticles is called I update the mesh property scalingDeterminant to try and zoom it, but I'm not seeing any effect. I may be doing this completely the wrong way but can't find anyone else scaling the mesh after initialisation (I'm doing it this way to avoid enumerating the particles as I thought it might be more efficient). I've modded a project in the playground so you can see what I'm trying -> https://www.babylonjs-playground.com/#ML2LR9#4 Any advice for a noob? Thanks in advance Ryan Quote Link to comment Share on other sites More sharing options...
