Imagine what you can do with an effect as versatile as this concerning the creation of mattes for motion graphcs!ĭownload both Blendfile and Video in high quality here! Now you can render a cool wipe of ink through water effect. When finished, move the camera in quite a bit so the movement of the sphere starts and stops off-screen. Things should be all set now so you can start baking. The settings of the domain can be found in the following figure: This means that the strenght of the moving Turbulence Force Field in the scene needs to be increased, though. I also reduced the number of divisions to 96 and added one High Resolution Division to save baking time. I changed the Reflection Color of the Volume Material from red to blue.
Notice that the emission is set to Volume and Random: The settings for the Emission are shown in the next figure. Turn off the rendering of the emitter under the Render section and in the Velocity section turn up the value of the Normal under Emitter Geometry to 4. The default setup is already quite useful. Turn the Temperature Difference all the way to 0 and check the box next to Initial Velocity.
Next set the physics of the sphere to Smoke | Flow, which will automatically create a particle system.
Move the tiny sphere to the opposite side of the domain and insert another keyframe. Insert a keyframe for the location and go to frame 100. Next move it to the left side of the domain, keeping it a little away from the wall. Then add an icosphere which needs to be scaled to one tenth of its original size by hitting S and then 0.1 on the Numpad. So what needs to be done? First delete the wind force field and the emitter plane. The finished Blendfile from that tutorial is the starting Blendfile for this one. This quick tip builds upon the inkdrop tutorial, so you should check out that one first.
