please don't worry about you're tutorials being too long as long as there full of details and good information there will be people like me that will watch every second and minute i promise, ignore people who say that it is to long those people are not serious about there art or craft, short tutorials are always missing info and that's the worst thing ever. good tutorial.

glad to hear that! cheers.

Another fantastic tutorial and great example of thinking outside the box. Thanks Pablo!.

Glad you liked it!

Thanks alot !! i really learnt alot about fibermesh . Also you can use the usual move brush while increasing "Preserve Length" to 100 to not affect the fiber's length

Absolutely incredible and done in a way I’d never have thought of. I’ll definitely be looking to make a few versions of these for myself.

Cheers! glad you find it useful

This is an incredible tutorial and very timely. I'm working on procedurally created eyes but I will definitely try it this technique for generating irises like this and see how it looks in Unity

Glad this helps! I'd love to see the results of the procedural eyes in Uinity, good luck!

@ I do have them on my Instagram. It's completely procedural, but I'm tempted to try this ZBrush method. It looks bananas

[@GregCalas]
