5. Set its Start Time to 1.0 and 2.0 and its Start Size to 1.2.
The particles happily work together.
Some sparks would be a nice addition.
Fire Sparks:
1. Create a new particle System and name it Fire Sparks.
2. Position it next to the fire.
3. In the Renderer module, set its material to Spark.
4. Turn on Prewarm.
5. Set Start Lifetime to 0.5 and 1.5.
6. Set Start Speed to 0.1 and 2.
7. Set Start Size to 0.01 and 0.08.
8. Make sure Simulation Space is set to Local.
9. For Emission, set the Rate to 50.
10. Set Max Particles to 100.
11. For Shape, use Cone set to 0 Angle and 0.7 Radius or whatever you need to restrict it to the
radius of the fire.
12. Turn on Velocity over Time and change it to Random between Two Constants.
13. Set their second x, y, z values to 0.5.
