Matthew Dizon - Sketchbook

Weight Painting done. Next is to work on Blend Shapes.

Modelled and textured necronomicon, Futaba’s persona because there was still some UV space left as I was making a new material. The new material for Futaba is for her eyelid and brow transparency, while I was at it I included the eye glass and outer eye ball transparency. Even did extra hair strands to experiment some texturing techniques.

Added Visemes, Mood and Eye Simulation Blendshapes that would make this rig VR Chat ready. First time doing Blendshapes in Blender. Getting the hang of it.

Now trying to pose her, before starting a live wallpaper like animation that I want to upload to sketchfab

Going to use this composition and animate it into something like a wallpaper and upload to sketchfab.
I do feel a lack of contrast, too much things and no focus so I’ll be working more on the lighting and post effects of that when in the Sketchfab editor.

I ran into a bug where the model would disappear during the animation. I was banging my head against the wall until I found some settings during Unity animation tests that the blendshapes were the cause. Certain import settings that handle blendshape normals created the problem below but at least the model wasn’t disappearing into the void. I LATER FOUND THE PROBLEM, was blendshapes being assigned any vertex group… Taking off the vertex group for all the blendshapes fixed the problems.

I was finally able to proceed and complete my rig and viseme tests in Unity. The initial aim was to make blendshapes and a rig from scratch that is a realtime asset standard, like something VR Chat is accustomed to and meets requirements. Although the model and textures itself is aimed for higher definition games or realtime products, there are always ways to downscale for optimisation, where upscaling would be much harder. I’ll be venturing into a workflow to decimate, atlas and lower texture res if I decide to make VR Chat or Second Life or other Video Game ready assets in the future.

Here is the humanoid retargetted animation test. I had problems with my toe pivot driver bones because it was required the toe not be parented to the feet. I had to delete the pivot setup so I can parent the toes to the feet and fix the humanoid avatar configuration.

This test is using the OVR Lipsync asset. VR Chat also uses this asset for their lip syncing. This gif can’t play audio but there is an audio file of someone talking and OVR Lipsync is lip syncing to the audio.

Then got to just doing an export test into sketchfab, fingers crossed that the baked animations made it across.

Working on making a 3D Printable model

Right now the plan is to

  1. Do the extra thing to add the extra details of the metal screw buttons on the belt and the lines and detail of the shoes. Then use Boolean operations to cut into those areas.
  2. Then use the 3D Print addon to check for current issues as I suspect the Glass frame and the eye lashes will be too thin.
  3. After adjusting things to be 3D Print friendly in Blender, seperate the Eye Glass frame with the handle. Then create the ball connectors using boolean operations.
  4. Duplicate the head and then boolean that with the goggles
  5. Add extra edge loops onto the goggles to maintain shape when subdivided later.
  6. Smooth and finalise the refinement of the wig mesh
  7. Export the Glass Handles, Hairs and Goggles to Zbrush
  8. Add hair strands to the extra hair curve meshes
  9. Refine the scalp mesh to properly fit with the other imported meshes
  10. Subdivide and finalise the goggles and every other mesh
  11. Join everything together with the Scalp and dynamesh
  12. Decimate and then import into Blender
  13. Check that the mesh isn’t protruding into head, if it is. Use boolean operations.

Extra sculpted detail had to be done manually again because I couldn’t figure out a way to do some sort of clean height map to mesh operation. Next time with this pipeline when in the sculpting phase, I’ll have a 3D Printing mindset to work out details that I’ll keep and then texture everything. My mindset during sculpt is to not bother much about cloth detailing and other detailing like on the shoes because I always basically do high level detailing in the texturing phase.

Huge Mistake Made…

Using Blender Boolean from past and present experience is a death sentence to time, heart and my brain. Next time I need to use Booleans for figurines, I’ll look into ZbrushCore Dynamesh Boolean.

In addition, I shouldn’t be too quick to move on after keying in the mesh to be Dynamesh in ZbrushCore as it efficiently keeps the unchanged vertices from being affected, so I could have done the boolean operations here and there and made parts fit together for printing all in Z Brush Core…

The only thing I have to fix in Blender is when Dynamesh failed to properly get rid of geometry that stays preserved inside the mesh itself.

I can even do the modelling of extra parts in Blender and import it into ZBrushCore then dynamesh boolean them together

Now 3D Printing

I used Blender boolean to create the connectors, they had no problems to it. The only thing that it didn’t work well for me in the past is adding details to the sculpts. Next time I’ll use ZBrushCore Dynamesh Boolean to work on geometry detail and use Blender boolean for precise operations like the connectors.

Off to print!

After the first bundle, the eye glass handles didn’t even print in my FDM printer, I need to thicken it.
The front hair strand was too thin, ended up accidentally snapping the left side when pulling supports. Going to need to re-thicken those hair strands.

I’m thinking of merging the Eye Glasses with the Hair mesh, it might work while I’m thickening the glasses.
Also I think the Pedestal is too big, I can see why many figurines have really small pedestals with simpler postures/ stances. There’s a convenience with mobility and the ability to place with a lot of other figurines. I’m going to decrease the diameter of the pedestal.

After this first prototype is printed. I’ll be printing a second with the fixes to the hair, glasses and pedestal.

After 3 trial and error fixes

I’ve learnt to ensure connectors have extra space after boolean process, some experience with flexing attempts (hair snapped 2 times trying to pry head in) and how much thickness is needed to fail less prints.

This is a preview shot, using weak glue so I can later disassemble for easy sanding.
The next thing to do is to sand, filler prime, sand more, putty, more sanding, gap filler, more sanding and spray paint. I may try to look into painting but I won’t be touching this 3D print for a while, going to jump into a new project for the time being.

Custom 3D Printed Cardboard Clamp to hold up cardboard for a window. The use of the cardboard is to cover the window and hold together a Portable air conditioner exhaust pipe, the position of the AC is too far to have the full window closed properly, so I had to find another way and stop cold air coming out. So made this in Blender and 3D Printed it.

This is an old design, and failed because it had no flex, no length and not enough space to allow the long clamp to connect.

Learnt to use Blender hair and cycles

Simple Lessons to take:

  • Scoping down details is important, but there’s no high details to areas of high importance. Everything was simple ‘flat’ surfaces.
  • In terms of better details, use better colouring, sculpt/ light, object density and texturing
  • Improve Dynamics (Posture, emotion and context). Things like the hair flowing and the background, as well as the characters action/ pose speaks louder than just ‘aesthetics’
  • Can improve context/ story for the foreground using 3D props etc
  • Background abstracts can be better coordinated with 3D objects. Also don’t be afraid to have bright parts in the background, if it can pull off better composition structure.
  • Texture wise, details were just bland not much variety. But most importantly the normal map was way too high, I had resorted to blurring during composition… to get rid of the uncanny ‘3D’ artifacts.

Brevity Summary: ‘Fun’, Colours, ‘Play’, Dynamics, Context, Composition Structure, variety and sharper details to improve.

Note; lighting was well done by the render. I feel like if there was more emotion, interest, story and something actually worth drawing the eyes, It would grant me reason to allow the lights to play around points of interest.

Small 3D Print Project, creating a friction cylinder (minimise pressure and friction) which is just to cover a piece of metal on my Exercise Bench. I’ll then move on to adding wheel and handle attachment so I can easily move and position the bench.

AND also making an Anime like character

Semi Real Anime Render Project I aim to complete in 2 weeks

Posing in Daz3D


Sculpting Pose

New tricks I’m learning with the anime style, mouth as boolean and using a lot of subdiv, solidify and edge split modifiers to save time on modelling the clothes. Used Array Modifier and Curves on the Chains. Used Path and Bezier Circle technique to make the hair.

Unwrap and Topology (Setting up Low and High Poly)

Environment - Learnt new things here; Cloth Sculpt Brush for mattress and curtains. Then array and screw modifiers to create a rope to follow a curve

Current WIP Preview (Wireframe)

Worked on the shading of the hair curves using this tutorial

And more Tweaking

Since this is my first time attempting a ‘Semi-Real 3D Anime’ Style, I’m still experimenting and figuring things out. The head was a challenge as well as all the values related to shading, lights and textures…
I’ve found out that using Emissive Texture Maps as part of the whole texture brings out this stylised toon look.

A worry I have is with the face and head looking ‘uncanny’ because of how I’m mixing realistic PBR lighting with anime. At first I thought this would result in a Figurine look, but the Emissives have just veered that feeling away. I like how the shading looks and I don’t want to tweak things any further. So I think I’ll just leave things there. Although I feel the light around her chest is too strong, might lower those values somehow.

On the other hand a problem I’m facing is the loss of height map values, like ab detail and cloth folds. I feel like my current light rig has washed those details away…
I really like the current look, but still want to get those details back. I hope I can play around with a new Key Light and highlight those details while still keeping this render looking good as is right now.

On second thought the lights ‘washing’ the ab details and cloth folds away isn’t a bad thing, I feel I’m just going to overdo it and lose the subtlety that this light has made, in a good way it has made those details more subtle but still retain them very softly. Usually we’re all prone to over exaggerate everything, I’m going to stick with this current light detail and just slightly lower the light intensity hitting the chest.
