Hi Ruochun,
Thank you ,It's okay, I'll explore SPH simulation myself later.I encountered this error after installing the VSG module : FATAL: VulkanSceneGraph not compiled with GLSLang, unacompile ble to shaders. I don't know how to solve it Page 在2023年10月23日星期一 UTC+8 17:19:51<Ruochun Zhang> 写道： > Hi Page, > > That movie is about an SPH simulation.
