Interesting way to create a flame and welcome to the site, your english is great, no problems there.
Sometimes I start with a set transform, then add a few linears, and then a random transform to see what happens. Then I move them about, sometimes change the start transform again. I like to alter the 3D parameters of the triangles to get different looks on it as well.
If it’s a variation with a lot of parameters, I’ll tweak those, I usually click right or left to jump ahead so I can jump back if it messes things up.
All in all it’s a bit random in approach, rarely do I set out with something in mind.
Great thread idea Joy 🙂
