    I've been porting an old xna game I wrote into unity. So far, I've been very successful. Today I wanted to begin making some weapon effects (plasma/electrical explosions) and, so, started getting into the basic particle system component.

    Particles look nothing like any of the tutorials on the youtube, even those from 2019, nor do they look anything like what is found at :
    "https://learn.unity.com/tutorial/introduction-to-particle-systems#5cf7ca71edbc2a09d0290dca"

    All the particles are pink squares. Changes to any of the items that should affect color do nothing (e.g. color over lifetime). I'm using Unity Version 2019.4.0f1. Am I buggy, or missing something fundamental about how the particle system modules (https://docs.unity3d.com/Manual/ParticleSystemModules.html) are supposed to work?

    This behavior occurs with a new project, empty scene, with the system attached to an empty gameobject.

    Many thanks,

    Pink/purple on some surface means that you have a material that is either missing, or it's somehow broken, or the shader does not compile. And that's why the surface renders like that.

    This question has been answered many times, if you had just searched for "Unity pink/purple particles" you would have gotten many answers.

    I just updated to 2019.4 and some of my particles were displaying pink squares. For me, the problem was that Unity randomly cleared some of the Material fields in the particles. Try to remember which material was there before and reassign it.

    Missed opportunity here. I searched for that query, and this is the top page hit. Sadly no real answers to be found. That's the result of focussing on the person and not the question, providing meaningful referral links or quotes that contain answers would have been helpful.

    @Freudarian was it really necessary to necro this post? And how exactly did you contribute to this question with your complaints almost 1.5 years later?

    If you don't want to answer someone's question you should just move on to the next post. Guess what, I've just googled Unity pink particles and google showed me a post full of your complains. Not useful at all.
