Here's the way I did it - if you increase particle lifetime you can see the transparency effect a lil better RandPuddleSplashesParticles_xpSprite.c4d

I'll try xpColor modifier. I also solved this way: Use an xpSprite disk with huge inner radius so it looks like a circle spline. Put a regular material on it. Then, in the Transparency channel use xpSpriteShader and attach the xpEmitter to it - then just need to select Mode = 'Parameter Dependent' and choose paramater = particle life and use B/W gradient.

Not exactly - I see you keyframed transparency in the material, which changes transparency of all the particles the same way. ie. at any given time the transparency of all particles is exactly the same. I guess what I really want is that transparency to fade in relation to how old each particle is, so at any given time the particle transparencies will be different depending upon how old they are. Thanks for your help on this.

No, I don't have Cycles, just use physical

Hello - I'm generating circle splines and growing them up. But I'm stuck on how to fade color to transparent. I have an xpMaterial on xpGenerator but playing with transparency over time doesn't give me what I want. And if I move the xpMaterial onto the emitter the entire circle volume is rendered instead of just the spline. thks for help if you can! RandPuddleSplashesParticles.c4d

Yes - Indexed check box did the trick, dang, thought I clicked everything

I tried random effector animated noise, too, but the motion still doesn't look random in 3D space3 - only on a 2D plane. On my file upload if you turn offshader effector and activate random effector and then pan around all the clones are on 2d planes moving around instead of all 3d directions.

Hi, Slapped a shader effector on cloner and set up an animated noise - but result is not what I expected. I want clones flying around all willy nilly but they appear to just be moving linearly. I futzed around with noise spaces and a few other things but am stuck. Can someone please help? ShaderRandomMovement.c4d

Thank you very much for those replies and solutions

I'm stuck on getting this animation to loop and would appreciate someone taking a look. Is there a better or more precise way to approach this? I was hoping to keep it in all in C4D. Doors_0001.c4d
