I would like to be be able to specify a fixed height, but a range for the width in the "Size of particle" diagram. I would then like to be just able to adjust the width over the lifetime of the particle using the "Size over life" diagram.
For example, I want the size of particle to be 200 units high, and 50-100 units wide. Over it's lifetime, I want it to stay at 200 units high, and the width to increase overtime by 300%.
Have I missed something obvious or is there no direct way to do this?
thanks for your help
