Tree Week 4

Downscoped and downsized, my bonsai tree
I actually had a lot of trouble getting my bakes to come out correctly in the rocks, I had to re-do my low poly meshes and my low poly UVs to get them to reflect any of the cracks, creases, and chips I had put into the high poly versions of the rocks.  The branches were a bit finicky as well, but in the end not a terrible amount of work.  The tree sculpt I'm extremely satisfied with, it's basically the only thing about the project I'd be proud to show anyone, but I'd want to take another pass at my branches to do so.

Substance Crystals


This week's round of 2D assets was mainly visual effects stuff but since our tech artist is here and we don't have enough time to get into a really serious 3d sculpt I decided to get into Substance Texturing.  Truth be told I'm not a very experienced Substance user, and I was hoping to take this opportunity to get a bit more advanced with the things you can do with stuff like Curvature mapping.  Jackson sent me a really great Marmoset Toolbag tutorial to get refraction and a bunch of neat effects but unfortunately I'm not a proficient enough Substance user yet to really get to where he got so much of the night was spent googling and experimenting.

To start I added a simple fill layer with about the color I was hoping to have in the center of the crystal.

 Next was to add some shine to the crystal to try to sell that polished surface
Next a gradient to give the tips of the crystals some pop and set a darker color to the tops of the crystals so they'd be more homogynous at the ceiling.
 Adding a bit of edge lighting was the next step.  I got this subtle effect by adding a curvature bitmap mask to a pink fill layer. This emphasized the edges of the crystal without me having to manually paint them in.  It's still a bit clunky for my tastes but on larger projects like a crystal ceiling pieces with individual crystals it would be very efficient.
Finally I added an emissive channel and 3D gradient to the bottom of the crystal so that it could be toned down and used to create a glow effect in the scene once ported to unreal.

Week 2 Environment - Bonsai Tree

Pivoting away from my original plan that was going to take way WAY more time than I had with my new responsibilities as a capstone lead, I've decided to scale down my project considerably.  How considerably you may ask well... how does under a foot tall sound?

 Yup, pivoting away from my cavern filling tree of roots and pools, I'm scaling down to a bonsai tree.  I'll still be incorporating the proxy rocks I developed last week, but for now I've focused on the tree pretty much exclusively. 


Nailing the texture of the bark has been difficult because I've been pretty focused on the twist of the "strands" in the bark.  If I can find or make a good brush that I can pull along the flow of the twists in the bark I can get this thing looking pretty great, I just need to figure out how I can get that done without it looking samey.

Week 1 Environment Reference and Proxies









My intentions for the environment are to use roots as elevated pools of water that lead from the smooth cave walls where water has eroded and smoothed out the rocks and work my way up to a petrified tree that gets greener as it reaches the top with vibrant foliage.  The surrounding structures will be shaped into roots which separate the surrounding water into distinct pools of water.

 The surrounding cave wall will be eroded into a smooth structure with more angular, chunky rocks coming together at the top to make a hole in the above cave to let light in to nourish the tree.
After a pass in Zbrush I'm hoping these rocks will come together as building blocks for the non-eroded rocks that surround the cave walls.  I imagine I'll have to make more as time goes on, but a lot of my work will be able to be saved after the sculpt by using some of Zbrush's more advanced transform abilities to create arched rocks or even circularize some of my existing rocks or groups of rocks.

Week 4 Prometheus


This week I was interested in breaking down Prometheus' armor a bit more so I did some concepting, we wanted to work with the original color pallet amount of white and additionally gold or purple to show divinity or dignity/power.

Week 3 Deer

Week 3 of our medium complexity character has me saying my final goodbyes to my antlered friend.  Most of my work today was done in substance painter save an error I encountered because I had to take a second pass at softening my mesh.

Step 1. Bake High Poly
I only had to re-bake my mesh because I didn't soften my edges enough in my Maya Export, which I only noticed once I started to dive into the painting process.


 Step 2. Fill
I started with the Deer's base color coat and worked with that as my background for the rest of the texturing process.
 Step 3. Details
I wanted to take care of the tail first and use that as a rubric for how I would approach the rest of the texturing process because it was an island of detail that I could use to test how things looked.  Once I was mostly satisfied with the result I moved on to larger texturing spaces.
 Step 4. Large surface Color
Here I took a crack at the antlers and general coloration of the body of the deer.  I wanted to save the orange/gold highlight on top so I mostly kept to darker tones everywhere save the chest fur.  I tried a couple times to get the lightness of the fur just along those sculpted tufts but unfortunately it just never turned out the way I would have liked.
 Step 5. Highlights and Fur Blending
Here I feel the mesh really came to life, the addition of the oranges to the deer's coat really helped it to feel vibrant and alive.  To contrast the purples at the deer's feet help to bring the viewer's attention higher on the figure while still looking at home with the rest of the very warm tones.
 Step 6.  Universal Rough and Metalic
Here I simply took a fill layer and turned off the color, normal, spectacular, and emissive channels to give the mesh a universally applied amount of roughness and metallic. I'm a big fan of matte looks on models, especially for living creatures so I kept the values below .5.
 Step 7. Emissive Eyes and Antlers
The final element I added in Substance Painter was touches of blue at the tips of the antlers, a few dots along the body of the antlers, and finally the deer's eyes.  The base color of these dots is a darker blue with a lighter blue as the emissed color.  I think the emissed color is a little strong, so I'd like to work to show off the base color a little more in the future.
Step 8. Import into Unreal and Spin
It'd been a good bit since I set up my fish rotation so I had to knock the rust off with such a simple blueprint but nothing a few minutes of testing couldn't fix.

Strangely, my attempts to export an optimized .GIF actually ended me with a much larger file than when I exported an unoptimized file. 




Final Note:
Something interesting happened when I was working in substance painter and wanted to add the Emissive channel to the texture set, when I clicked the + to add the channel I saw it highlight as if it were clicked but no menu to speak of.  However, when substance was the only thing up on my monitors, I noticed substance had placed the menu up on the screen above my cintiq.  I'm not sure if this exclusive to tablet style displays but I'd be interested in testing to see if it happens and just let people know if you don't see a menu you should, check your other monitors.

Medium Complexity Character Week 2

Medium Complexity Character Week 2
Retopology, poly paint, and baking

The first step to retopo is importing your decimated high-poly mesh into Maya and setting it to be your active live-surface.  Quad-draw is your friend and enemy here, as getting a hang of the finickiness of the tool can be a real pain.  For stuff like the base of the antlers, the shoulders, hooves, tail, eyes, and the little fur tip at the back of the deer's leg I would recommend setting up a circular set of quads that encompass the area in question.  Just be careful about how many polys you use for this step, as it can get your polycount pretty high very quickly.

Prometheus Round 2 - Robot Ideation

Taking the feedback from the first round of robots I presented to the group and to Nick, I worked on a few more designs based on the chosen silhouette. After talking with the team, we wanted to give the robots cloth in some way, not necessarily attached to them but in some way draped around them, and with the silhouette that I got, the figure really spoke to me as a robed figure and most of my designs reflect this.
