Title: Esben's Tutorials (+ Rust, color animation and bead blasted aluminum)
Post by: Esben Oxholm on January 12, 2017, 02:06:40 AM
Hi guys  :)

Just wanted to share a tutorial with you that I recently created.
It shows the process of creating a hammered metal material using the material graph in KeyShot.

Thanks for watching.
Best,

Nice ! I learned a couple of things from this. Thanks for sharing.

Very nice tutorial. I have a few comments regarding the technical construction of the graph (merely suggestions):

Since the cellular texture has the same shape/appearance for all instances, I suggest using a single cellular texture node with the colors you want to use for the metal. You can use the same cellular node for bump and color - the bump height is not affected by the colors you define. For roughness, I suggest running the same (single) cellular node through either a Color to Number or a color gradient remapping - that way you convert the existing color output into a more suitable range fo the roughness you desire.

One key advantage of this approach, is that if you wish to change the scale later, you only need to do it one place; this is particular convenient for somebody else using the material.

/Søren

[Edit]
Instead of assigning the metal colors to the cellular it would be better to use black and white and use a color gradient remapping to define the colors. Otherwise the range of the roughness will be limited to the brightness of the two metal colors (hope that makes sense).

Excellent!

Will be perfect for creating metal welds.  :)

Thanks, all!

A great bunch of tips, Søren.
I actually thought that the brightness of the colors affected the bump-height. Good to know they do not!
Also, I never realised you could use the gradient to 're-map' colors. Awesome!

I tried implementing all your suggestions and I totally understand the benefit from this.
Sometimes I just think that the graph looks more cluttered and confusing this way.
I have dreamt a lot about a global scale multiplier for materials: A slider that scales all used maps in a material proportionally  8)

Thanks again for the wisdom!

Great tutorial again! After using KeyShot for a while, it's good to know that there are new things to learn.
Thank you!

I honestly hadn't used a texture on weight 1 and weight 2 before. Nice job getting lots of milage out of one simple image texture.

I echo the comments of Will and LayC42 - Awesome technique!

Ha, me neither :D
I normally layer different materials and use the map in the opacity channel to get this effect, but using a map on the bump weight might be handy in some situations.

There's always something elegant and attractive about efficiency.

Nice tutorial, Esben :) The Surface Backside Mask node is one of my absolute favorites; I use it quite often. So many cool things that can be done with it!

Great tutorial Esben as always :)
why we can see a poodle in your video ?  ;D
Title: Re: Esben's Tutorials (+ Polarized Glass)
Post by: DriesV on February 09, 2017, 10:44:09 AM
Because it is snowing in Denmark?
Just a guess... :)
Or maybe it is subliminal messaging to get us to buy cute snowy dogs.

Cool tutorial btw!

Haha, thank you all.

The dog (the actual one on the picture - yes, it is snowing these days in Denmark) was barking in the background and I thought it might as well get a few frames of fame. Maybe it's harder to hear than I thought? :)

Great tutorial, Esben. I love that clock animation. I've checked some of your more organic and character type stuff on Instagram, and it's clear that you have a great animation sense. I'd be willing to bet you've studied Lasseter's "12 Principles" and probably have a copy of Disney's "The Illusion of Life" in your library  ;)

Cheers,
Eric

Thanks a lot, Eric.
You hit the jackpot! At least half of it. I have viewed a lot of videos on youtube on the 12 principles. Good stuff to know about when it comes to animation :)

Haven't checked out 'the illusion of life. Probably should.
