Hi, I have been trying to do the “Particle Fun” tutorial by Niels Prayer here{https://www.sidefx.com/tutorials/particles-fun/ [www.sidefx.com]] but I am stuck because the instructor shows to use the “mantra surface” material, I don't have it for some reason. I have restarted Houdini, tried the tutorial again, and even tried using the only material like his that my Houdini has (called “Principled Shader”) but nothing works for me. I am using the non-commercial version of Houdini FX 16.5.473, and it is the Mac OS X version. All hope is greatly appreciated!

Thanks,
Benjamin

Try the “classic shader”.
