I am messing around in Opentoonz to see if I find something that'll help me when it's time for me to start on my series or anything cool in general, Here's a render of water.
I've not done that before but if I were to try, I think I'd use a matte out node, With the shader as the... Source, I believe and the element as the matte. Please link me if you post! 🤞👍 (I just realized how I said this, What I meant was that I wanted to see the results, I was asking for a link. 😅)
