Hi, thanks for your input on this, but I think you're targeting the wrong place to add docs for smoothStep. You need to place it here:

p5.js/src/strands/p5.strands.js

Line 223 in 626996e

* @property {Object} combineColors

see how we have combineColors() you should add smoothStep in the same way. Feel free to reach out at discord if you have any questions. Anyways, thanks for your input on this.

Hi,
Thanks for the pointer! I see that src/strands/p5.strands.js exists in commit 626996e, but it doesn’t look like it’s on main yet.
Should I:
Wait until this lands on main? or
Base my PR on the branch that includes this commit?

Thanks for the review!
As per feedback, this documentation belongs in the p5.strands API rather than baseStrokeShader. I’ve opened a new PR targeting dev-2.0 with the docs added in src/strands/p5.strands.js.

Closing this PR in favor of the new one.
