  • What is the best way to ensure that voronoi fragments get smaller and fade out?

    Posted by Hilary Tsai on February 1, 2023 at 1:39 am

    I have a voronoi exploding sphere that collides with another object. I want to have the exploding bits get smaller and smaller, and appear to dissipate into the air rather than remain large. I know there’s a way to do with with random effector falloff, but I don’t know how to combine that with the rigid body dynamics, as it seems to be an entirely different technique that is not used in conjunction with others. Is there another way to do this? I was not able to find much information using these search terms.

    Thank you so much

    One of the best ways for you to get the required result is to use an effector.

    First, make the voronoi fragments a child of a plan effector.

    Under plan effector click on parameter tick out position, tick on the scale (take scale to -1 and tick uniform scale), go to falloff, click and select linear field.

    Go back to the effector click one random, go to parameter change all positions to 10cm or a required size, click and select linear field.

    Final step:

    Click on the linear field (child of plain) and drag to the left-hand side

    Do the same for the linear field (child of random) and place like an inch behind the first linear field (child of plain)

    Second solution:

    This might be a long process but could have better results.

    First thing after making your model use the knife to create more polygons right click and select subdivide, go to effector and click Polly effect, then make it a child of the model.

    Now with your Polly effector, select a random effector (from the effector panel)

    Go back to your Polly effector pick falloff, and select linear field

    Increase falloff to 100.

    Just move your effect from right to left and adjust the values to create your desired effect.

    Amazing! Thank you so much for these solutions – I will certainly try them both out!
