1,000 Physics Objects falling into a pile in Blender | Quarantine Series 2-9

Описание: Multiply a physics cylinder object by 1,000 and then watch them all fall into a big pile. Of course, we'll need to fix several problems along the way. (Blender 2.83.5) - Timestamps Below:

INTRO:

0:00 - Preview
0:13 - Setup
0:44 - Tweak
1:08 - Clean up outliner


CREATE 1,000 CYLINDERS FALLING INTO A PILE:

1:50 - Array Modifier
4:09 - Assign to proper collection
4:55 - Separate by loose parts
5:12 - Random colors
5:44 - Orgins in a single point cause explosions
6:33 - Select all objects in a collection
7:26 - Set Origin to Geometry
7:40 - Test the simulation


FIX OBJECTS THAT ARE CLIPPING INTO EACH OTHER:

7:53 - Show & explain clipping
8:17 - Change object outline color (optional)
8:40 - Set "Collision Margin"
9:37 - Copy settings to all other objects
9:57 - Test the simulation


FIX OBJECTS FALLING THROUGH THE FLOOR:

10:35 - Show objects falling through floor
11:00 - Set all objects to a scale of 1 (Apply scale with Ctrl+A -- Scale)
11:25 - Subdivide your floor (and other objects if needed)
11:55 - Split Impulse
12:25 - Steps per second & Solver iterations
13:30 - Test the simulation


CREATE A DUPLICATE COLLECTION FOR OUR SIMULATION:

14:01 - A litte explanation
14:30 - The wrong way - duplicate within the same physics collection
15:23 - Objects floating in mid-air
16:06 - Disabled View Layers STILL contribue to physics simulations
17:07 - The right way - duplicate and move to a different physics collection
18:12 - Fix glitches
18:21 - Test the simulation


CREATE A MORE COMPACT PILE:

18:42 - Objects are rolling off the floor
19:10 - Apply Transformation
20:30 - Remove rigid body from objects
20:47 - Unlink the automatic duplicates
20:37 - Non-desctructive workflow - Fall back on original collection
