When im trying to do cartoony effects i usually go with highlights.
I make a script that goes thru ever child in workspace and than just creating a new highlight effect for the object.
The configurations is obviouse im guessing so yea.
As far as I know, the only real way to create assets like this is to cell shade each asset and model in Blender or any other 3D software you might use, and import it to Roblox, there are other “ways” to replicate the effect, but they’re not effective and they’re really time-consuming :<
(Keep in mind that this is really just meant to build your fundamental knowledge on the basics, don’t expect after watching the first 2 tutorials, you can easily replicate the bendy style, especially if you have no knowledge of how to use blender at all)
One last thing, highlights are cool, but not very effective and can be kinda laggy, that’s why you don’t see a lot of games using highlights on very big assets like maps and stuff
Hope this helps, sorry if didn’t answer your question :<
