Reymond Textures, Leaves and Trees

Week 17 -18 (2018/01/15 – 2018/01/26)

Technical and Artistry

I tried to match Reymonds textures in Substance Painter to my previous concept art of him. We’re trying to keep with Reymond’s scene being a mix of warm oranges from Reymond and cold blue moonlight.

 

These textures might need more work if they make the facial expressions too flat. Alec suggested using an ambient occulsion pass to help define features.

For Reymond’s leaves I modelled one branch of tertiary/smaller branches and leaves and then distributed this using the MASH placer node. MASH is somewhat fidgety in that it doesn’t always distribute geometry near the cursor or if I create a selection set of geometry it sometimes only distributes across the first few members of the set. I’ve also had trouble with getting the MASH network branches to move with Reymond’s geometry. There might be a setting to fix this in Maya 2018 but for now we’re doing all of our setups in 2017.

 

I tried adding a small amount of animation to the MASH repromesh by animating each of the original leaves. Animations can be easily looped, offset or scaled by using a MASH time node. This node can only be used on MASH copies (repro) rather than instanced meshes though. My result is a little too subtle but it’s something I’ll come back to if we have time to add environmental animations.

 

In semester two, week one I mostly concentrated on trees before Kerry and I started a full asset list for proxy models and set layout. I finished off the tree models that I had started before Christmas, UV unwrapped them and then textured them in Substance Painter.

 

 

I tried a different approach to leaves with groups of leaves on an image plane instead of every leaf being on one plane.

 

 

I tried using a blue texture plugged into emission to control the shadow color.

Reymond Progress

06/Jan/2018 – 15/Jan/2018 – Technical and Artistry

I’ve been tasked with modeling Reymond. Below are the references that I was working from, from Andrew’s drawings and some of my own sketches from before Christmas. I had painted Reymond as a towering tree but Mike pointed out that Reymond’s framing would be completely changed with this, changing the comedic audience eye level in the animatic. I’ve therefore resized Reymond’s model to be more at an eye level with Nami and PĂșca.

Topology

I haven’t modeled any facial topology since first year so I started by looking back on my research from back then.

My previous research on head modeling: link

The topology reference from hippydrome came in the most useful:

http://hippydrome.com/

I choose to start with topology in Maya instead of organic sculpting. I drew out where I thought the edge-flow would be based on the reference from hippydrome. I tried duplicating this by moving edgeloops on a box at first but then I just found it easier to trace my drawing with the quad draw tool. This made a flat plane of facial topology which I then pushed, pulled and pinched with the Maya sculpting tools until it looked like my drawing. I tried to make him chiseled like in the sketch by pinching the topology closer together in places but I hope this doesn’t cause any problems with the facial blend shapes and rig.

I still need to add more hanging moss on Reymond’s branches and I’m going to experiment between Substance Painter or sculpted displacement maps to create his clumped moss.

I tried to create Reymond’s UVs in as automated a way as possible, as in my previous blog post rendering a tree. The unfold and layout tools have been working a lot better in Maya 2017 than they have before. I wonder if this is because I spent time using the mesh cleanup tool?

 

Look Development

Week 15 – Friday 2018/Jan/05 – Artistry and Technical

We’re trying to figure out how our cartoon world will be textured, shaded and composited. I tried making some simple textures in Substance Painter and brought them into Maya with the aim of combining them with a cartoony shading and lighting method.

 

 

I tried applying toon shading with the facing ratio shader to my tree model (Arnold tutorial) but did not like the result as it doesn’t pay attention to my light setup.

 

 

I’ve been trying to figure out how to render lights separately in Arnold for a long time and it turns out that it’s extremely simple. I found instructions for using AOV light groups on the bottom of this page:

https://support.solidangle.com/display/A5AFMUG/AOVs

By rendering lights separately we could maybe play with the contrast in post for getting the look that we want? Somewhere between cel shaded and having soft glows in places. This is what I’ve got from Nuke so far by rendering direct and indirect AOVs for three lights: dome, key directional and rim:

 

 

This tutorial was useful for UV unwrapping the tree. It makes the process as automated as possible, using planar mapping, auto-seams, unfold and layout functions.

 

Andrew has shared this rendering tutorial with us which will hopefully help our look development.
