surprise_villain_01Bet that was your face when you saw my new eyebrows!

I’ve heard I’ll be getting a tongue and some shiny new teeth as well, but not yet… Not a priority they say…

 


J What a week and weekend! Black Friday really was a great one this year, allowing me to buy, among other things, the Substance Suite.

But I get ahead of myself, let’s start with week 37 which I dedicated to scripting new rigging tools for myself in Python. Since sharing is caring I extended one of them until it was user friendly enough for anyone to use.

It is a very simple script that allows for easy skinned joints selection based upon your own naming conventions. It’s the first in a range of free scripts I’ll be making available via my new Gumroad, so check it out!

Let’s move on to some art, here’s the first edition of Lech’s new texture, completely generated inside of Substance Designer with procedural eyebrows.

Comparison between new and old.

In the end however, I wasn’t happy with the look of this newly generated texture, I felt it took some of Lech’s personality away, at the very least, it changed it, also, the eyebrows were difficult to control and looked a bit too realistic for my taste.

What happened next, you wouldn’t believe! I split the graphs… Let’s start with the most important part, the skin generator, it simply takes inputs in the form of the textures generated from the high poly and outputs three textures. Albedo, Normal and Rest (R: AO G: Metalness B: Smoothness A: Emissive).

Skin graph click me!

A final note on the above graph for the people interested in the “FaceTemperatureHue” frame to the left, it’s simply a lot of shapes that create a pattern of red, yellow and blue based upon the science of face color areas. Look it up, it really does add a lot of (make sure it’s VERY subtle) interest to the face, which, when it’s half of your character’s body, is very important!

Next up is the eyebrow generator, which is a separate graph that can generate pretty much any kind of eyebrow I can image, it’s a bit clunky and when I start working on a mustache/beard generator I’m going to have to go about it more cleverly. As Neofur was also on Black Friday I’m planning on using the outputs from these to generate a separate texture for the inputs that Neofur needs as well.

Eyebrow graph click me!

Arguably more important than the graph itself is the parameters, here they are in all of their glory, rotating hairs, changing colors, moving, scaling and warping, what else could you need?

Here are three different brows that I’ve generated, once I’ve made the beard and mustache generator I’m probably going to recreate this one as well so I’m counting these as a low priority WIP for now.

Finally we come to this, the least impressive looking graph, it simply takes the bakes textures and inputs them into the skin graph, takes the skin output and blends it together with the eyebrow generator, in the case of Lech I’ve added some extra nose reddening since that fits in with his backstory.

Combine graph click me!

Here are a few steps inside of Unity where I’ve been using the Amplify Shader Editor to put together a custom shader capable of using the textures that Substance Designer has generated for me.

An important part of my workflow is that the UVs of all of our humanoids have the more or less exact same UV-layout, this allows me to use Transform 2D nodes to mask special regions and still know that the graph will work for another character.

Some things are not going to be the exact the same as you may imagine, Lech gets a small nose reddening and someone else may get some work done on a scar, something that is constant is however, lips and the fact that they are never the same size nor do they ever cover the exact same area. This is why there’s an extra, hand authored black and white map to take care of lips and mouth bag.

The final thing I worked on was an Ambrosia substance, not sure about it, why not leave a comment on it on our Facebook page, I’d love to get some input!

J Lech didn’t get a chance to say anything this week, and I don’t have that many words for you either, but let’s take a quick look-see at what I’ve been up to.

First up is a new rig for Ambrosia, or rather, the continuation of her rig, I’ve added some fleshy squash and stretch to her legs and I’ve also started to add some more definition to her face, as she’s a hero character that can only ever exist once in a scene, she deserves some more geometry, especially since the humans have already been refined.

Doesn’t look like much, but here’s a quick gif of what we can do now, not that we’d want to.

More importantly I’ve been working on the facial animations, specifically, I’ve been working on getting them into Unity, if you went to GameOn you’d’ve seen a rather sad preview of Lech talking to this female customer, her mouth open wide, jaw bouncing up and down and Lech’s disturbingly puckered lips.

After a few hours of trying to get the facial animations to work with the humanoid rig setting inside of Unity I switched over to generic, this is going to cause some other issues but after just a few minutes I had my first working animation.

Huzza! Sure, almost, you see, getting the animations to work consistently still wasn’t possible, despite my new exporter script helpers (I love Python!). Enter Maya Game Exporter, I might cover it in a short video in the future, for now, just try it out, it’s amazing. Using the Game Exporter in combination with some basic Python, everything works like a charm, every, single, time!

Here’s a short video on what it could look like (this is not what it’ll sound like though!)

I’ve also updated my post on Shader Forge vs Amplify Shader after the recent 1.29 SF and Beta 2 ASE update.


K So many things I ignored during the pre-GameOn event. But now I’ve had the time for some R&R and to handle most of those things and starting working on smaller fixes to get som functionality into a more stable state. So basically I’ve been all over the code base for some quality assurance.

Next step is either take what we have further to the next step or maybe starting on some dialog, but that sounds a bit early to me, maybe some basic customer behaviors, well it seems the next step is a meeting with Jona.
