It's a pretty basic concept with very large potential. What you are doing is using the RGB (and possibly Alpha) channels of an image to store up to four greyscale images that can be used as masks.



Here is a brick texture I made in Substance Designer based off some Pluralslight tutorial. I've labeled them respectively.



This one may look like some sort of cyberpunk nightmare but if I break it down into the three channels you'll find...





Three distinct greyscale images that are used for the Height (R), Roughness (G), and Ambient Occlusion (B) respectively. Now just use the RGB outputs of the file node in your material editor to use each respective mask.



This method is generally much easier to work with than using three separate mask files. It's essentially mask grouping. Now... if you're like me in college and self-taught yourself Photoshop you'll have no idea what channels are. Not knowing how to access or edit said channels makes this massively harder to understand.

Cool, yeah that's pretty easy to understand.

I was trying to figure this out, but visualizing what the node network would look like is hard:

Mhmm


I'll point out, at leased from what I remember, that using just the alpha channel in the combined rgba is almost as expensive as the rgb part on its own, so try to stick to using just the rgb and only alpha if its really necessary.

This one is interesting to recreate (* in Blender). They're basically doing something like this:


You can compute the lighting with a dot product function, and normalize it like in that diagram with a few extra operators.



Plug the brightness into a color ramp to get a cel shading effect.


You can combine that brightness with a separate shadow map. (from the green channel in this example.) If you multiply the brightness then it will accumulate darkness from multiple shadows overlapping, but if you use the minimum brightness then it will behave more like an actual shadow.


The ambient shadow colors get a bit more tricky. If you just multiply by the shadow color then it tints everything darker. What you want to do is multiply the diffuse color by white for the bright areas and the shadow color for the dark areas.

Amazing. Thank you so much. Will try to recreate this in Maya when I have time.

Anyone have experience selling assets on sites like TurboSquid? I was considering buying Maya LT (I currently use the educational version for personal stuff) and creating stuff to sell for beer money. Subscription costs are pretty hefty so I wouldn't want to take the risk if it's difficult or inconsistent to make profit.

Same thing as with stock images. You wont be making a living off of it unless you're making a constant stream of high quality assets and have a whole backlog thats in use. It's a little extra income. Unlike stock images the prices are wildly inconsistent and set by the authors so they're kind of ridiculously varied and suppressed by people desperate for sales? Also consider the unity/unreal asset stores for better exposure.

Does a website exist that offers free models that could be used to practice texturing? I’m too slow and unexperienced to make my own models at a pace fast enough.

CGTrader and TurboSquid have, I think, some models that are most likely free (but probably poo poo quality too!).

Sometimes ripped game models work, if that's what you're going for. A friend of mine used to practice handpainting textures on the Team Fortress 2 player models. You just paint over their existing texture sheets/uvs.

For you freelancers out there, Vermont is offering grants to relocate there if you work from home.

That's pretty cool

I have worked from home a little bit over the last few years and it really doesnt suit me at all, which sucks as it would make living arrangements a lot more flexible.

It just turns me into a grumpy hermit creature. I was even getting out for a run each day to keep active and prevent the sad brains but the lack of human contact wears me down.

I'm with Eoin, I've done the freelance lifestyle for about 2 years total now, scattered throughout 7 years of in-studio work and I much prefer working in a studio environment. It's much easier for me to seperate work and personal time, but being at home all the time it drives me nuts because I feel like I should be working even when I'm not.

I think the planets could use some more atmospheric blur around them, they look very stark against the star field. Especially the mechanical moon thing next to the planet.

I agree. A 20px gaussian blur at something like 40% might be enough to just help the background sit back a bit, but I'm digging the overall look.

The floor material in the interior looks quite good, but maybe the ceiling lights could get a bit more articulation?

ZBrush 2018.1 is now available for download.

This patch is a free update and is highly recommended for all users. It includes a number of changes for improved stability in ZBrush 2018:

NEW
Added various changes to increase ZBrush sculpting and navigation speed.
Added ‘Go To Unmasked Center’ button for use with Gizmo3D center option.
Added ‘Uvb’ and ‘Uvbt’ (UV-Box and UV-Box tiles) UV map creation options.
Added option to export Smooth Normals with OBJ files.
Added ZModeler Inset proportional option. (A Single Poly only. CTRL modifier)
Added a warning when loading custom brushes with auto-masking enabled if Sculptris Pro is active.
Added a MatCap Red Wax material so it will no longer be fully replaced when using ‘Save As Startup Material’.

we will never be free of this curse

If anything the screen right strap could have a more pleasing shape. Right now it's somewhere between a C and S curve and I think you could accentuate that.
