Understanding Reflection and Refraction by Satya Reddy, India

5. Now Place you Text or Logo any kind of Stuff in the center of the particles.



6. We can see that the Particles are animating at this stage, Now select the frame where you want to show the Text in the Scene in my case I selected the frame 105.



7. Now the particles are still animating and in order to stop the particles on 105 frame, we can do it in PFlow but it will be messy and the good idea is to Use Mesher tool. Goto the Compound Objects and select the Mesher draw the pyramid anywhere in the viewport.



8. Now go to the Modify panel of Mesher, select the pick Object none button and select the Particle FLow



9. Now we can see two particles in the viewport (ParticleFlow and Mesher) as we move the time slider both the particlesflow and mesher will animate together to break this chain simply right-click on the mesher particles and covert to poly.



And we can switch off the particle flow as they are no longer required now or delete it and place static particles right in place of particle flow there.

Now adjust the particles if they colliding with text or logo, Delete it by going to PolySelection - element and select the one to delete, move, rotate, scale. It's time to make things good, create a Camera and adjust it for the part to view right.
