Ortho / Perspective switch

As of this writing, the one thing in Blender that throws me off is the Ortho / Perspective switch. I sculpt in both modes, and usually have the Perspective at 120mm Focal Length. If I’m up closed on the mesh in Ortho mode and rotate the viewport, the mesh will vanish out of sight. To bring it back to view, I would have to scroll the mouse wheel up. This is solved by turning off the perspective auto switch in the preferences. The problem is that you would have to manually switch to perspective mode, and when you do, the mesh will vanish out of sight again, and then you would have to try to bring it back to view. That’s a lot of hassle. I can’t seem to find a way around this so that I can work with perspective autoswitch on.

Sculpting Hotkeys

Another Sphere head

Last night I took the time to mapped out the sculpting brushes so that I can easily get to it in future experiments. Blender sculpting is fun once you know the shortcuts to each individual brush. By logically organizing them, I’m able to experiment and try out more brushes on the fly.

Here’s another experiment earlier, and as you can tell, it’s based on a reference this time so it looks a bit more real, and not creaturely. In this test, I found myself using the “Clay” brush more, a lot more, because it’s a female head and things need to be round and smooth.

Clay Strips gives a rough look, and it’s a good brush to block in the form in the earlier stage of sculpting. It also gives you the clay effect. Yet at the same time, it can mess up the details that you have worked very hard on, if you’re not careful. When you already have a lot of details in place, use the Clay. If details don’t matter, use Clay Strips. If you want to be subtle, use Clay. I tend to use both the Clay/Clay Strips at 100% strength. At 100% strength, Clay Strips allow me to easily block in the form. I can still manage the strength via pressure sensitivity, but it’s at 100% strength that I use these two brushes. The SculptDraw brush on the other hand is very extreme. I would put both the Blob and SculptDraw in the same category.

Smooth and subtle. Brush’s strength is at 100%.

I use the Grab brush a lot throughout my sculpting session. Earlier stage to fix the overall shape / proportion. Mid stage to adjust / fix the proportion of the nose, mouth, etc… When the proportion or shape doesn’t look right, the Grab brush is your friend. A lot of time we tend to be so fixated on detailing our mesh that once we zoom out, things look off! This is normal by the way. That’s why the Grab brush will be used throughout. For subtle changes, we have the Thumb and Nudge brush. Thumb and Nudge works a bit differently, but both are there for minor and subtle changes that does not affect other area of the mesh. If the jawline is too high, you can bring it down with the Thumb brush.

More can be said about Scrape, Pinch, and the Crease brush. That’s for another post.

Blender needs Transpose

The hand is a challenge to draw, model and sculpt (digitally). Earlier I decided to give it a try, starting with a sphere. I didn’t bother to finish it because it’s way too much work to manually move and reposition the fingers. I enjoy sculpting things manually, and for those that do, Blender really need a way to quickly bend / rotate the mesh—something like the Transpose tool in ZBrush.

Here’s my tip if you want to sculpt the hand: Let the palm face you (front view, “1” on the numpad). That way, you can use your left hand as a reference.

Have Some Good Ref Near By

As of this writing, I work with a 15 inch screen at 2048 x 1280. What this means is that there’s not enough space to fill the screen with references, and because of that, I have a habit of doing things from memories. I’m a bit lazy to open up references when all I’m doing is experimental sculpting on the fly. For me, one way to counter this is to have an actual figure sitting on my desk. There. No more excuses for not getting the neck right. You simply can’t trust your memories as evidenced in the fact that people still forget where they put their keys (pun intended).

Also, take advantage of that empty wall of yours. Whatever you’re struggling with or needed to be reminded of, print them and stick it.

Experimenting with Environments

I spent two days just experimenting with these environment concepts. These were quick thumbnail sketches using just one brush throughout the entire experiment. Two things I’m not good at are: Environment and Mech. With these experiments, I’m trying out something new that is outside of my comfort zone.

Casual Perspective

One of the excuses that I had for not getting into environmental concept at first was that I didn’t know perspective that well. But when you think about it, most people that do character concepts don’t know perspective that well either (just enough to get by). When you start to have realism in mind and placing them in an environment or finishing that masterpiece of yours, that’s when it really matters. Same thing goes for muscle names in your studies. The major muscles and bones are enough, and you can always learn more later down the road, but it’s not necessary to start off learning every muscle and bone (you’re an artist, not a medical student).

How often do you see artists on the street have their rulers out when sketching/drawing from life? I don’t remember seeing one. Which means most of them are doing it casually. Not everything has to be perfectly lined up. It’s okay if your perspective is off when you’re quickly fleshing out your ideas. Afterall, these initial sketches aren’t meant to be final. They’re there to get [the point across]. This is the mindset or attitude that you perfectionists (speaking to myself as well) need to adopt. If I didn’t, I wouldn’t have carried out this experiment and learned something in the process.

Having said all that, here’s another thing to keep in mind: If you’re a [digital] artist, you don’t have to master perspective (you can if you want, if you got the time), anatomy or even lightning. Blender (or any 3d app) will help you with that. If you think that’s cheating, then you might as well go back to traditional medium :). The fact that you use the “undo” button and layers to assist you already say something.

SET 1

All the examples in this post were done freehand. And I quickly ran out of ideas because I’m inexperience in this area. Roughly 1-4 minutes each. Take note of the brush strokes…

SET 2

When you have nothing to look at, and you haven’t done environment that much, you will quickly run out of ideas. Scribbling is one of the ways that ideas can be quickly generated. To make it even more random, I did it with both eyes closed. Then I opened my eyes, duplicated that chaotic mess. And painted it over. Take note of the brush strokes. Notice how the last part of this second set is very different from all the previous ones. The first part of this second set is bold and straight to the point, with high contrast (dark/light). The brush’s opacity was at 50%. The second part of this second set has a lot more light values (brush’s opacity range from 10% to 50%). I was more relaxed and confident in the last part of this experiment, and it shows in the brush strokes.

Creatures and Re-topology

Modeling or sculpting creatures is a great way to learn the 3d app you’re using. Creatures allows you to make mistakes, and to be free and relaxed in your experimentation. With humanoid, you have to keep the anatomy in mind otherwise people can look at it and know that it’s off.

Sculpting this piece from a sphere was quick and easy. It’s also my first attempt at retopologizing. Blender by default has all the options and features that make this easy, but the actual process of retoplogizing (manually) can be long and tedious! I might have to look into RetopoFlow later on.

Another Speed Test (15 mins)

This time I slowed down and tried to be a lot more intentional with every stroke. I wanted to see if I could find a shortcut to block in a decent head form within 10 minutes from scratch (sphere). Apparently there is a shortcut. The shortcut is the “Grab” brush. After blocking in the basic planar of the head, take time and carefully reposition/adjust the shape of the head with the grab brush.

This looks like I won’t be going back to regular box modeling for organic/creature concept. Sculpt and Retoplogy is where I’m setting my eyes on. If I were to do this with regular box modeling, it would take a lot longer.

First attempt at Speed Sculpting

1 Hour Speed Sculpting in Blender 2.80 beta. Completed in 55 minutes. Started off with a Sphere.

Completed in 55 minutes. No reference. Forced myself to improvise. I was a bit nervous before I hit the clock and wasn’t sure if I could pull it off because 1) My knowledge of anatomy is still lacking (the neck gives it away, I think), 2) Still learning what each brush does. Would love to experiment with other brushes, but I stuck to what I know best: Clay Strips. My left hand was hitting a lot of hotkeys and I was going as fast as I could. There were a lot of hiccups in between as I reached the numpad keys with my right hand and that kind of slowed down a bit. I’m a keyboard cowboy and haven’t fully mapped Blender’s keys to my liking yet.

Anyway, I’m very surprised by the result. Let’s just say I got lucky!

Sphere Head

Another test piece. Done in Blender 2.80 beta.

I was going to abandon this test piece halfway, but persistence pays off. In case you’re wondering why:

It’s all about refinement, analyzing and correcting, from first to last. The mistake or mark we make becomes a point of reference. To have a nose that looks about right, it must begin by looking wrong. And that begins the refinement process.
