TEXTURING

TEXTURING

At first we decided to texture all the objects with one same white paper texture, so the objects would be subtly defined solely with different light qualities. After trying so, I found out that this wouldnt't work and would also make a discrepancy with the colorful character animation composited on the top. So I decided to include a bit of ink drawing on all the objects (to shade them), which was an enormous amount of work, which didn't really pay off. It simply didn't look good, it was blunt and dull and so I finally decided to texture them with different materials. Different qualities of texturing represent the dihotomy of two different worlds: the world of her imagination and the real world of hospital. First one is expressed through softness and lightness of paper, the second through roughness of cardboard and bump.

Color range also contrasts from one world to another, while being more bright and divinely innocent in the first, more dark and earthly in the second.

UV MAPPING and UV SNAPSHOTS:

After modeling I needed to sort out the UVs of every object in a scenes that I made (There was just Louis who actually sorted out UV's for the scene I assigned him, and Moe for the fish I gave him to be rigged, all the rest were done by me). They are mainly all polygons, except few NURBS and subdivs. Texturing NURBS is much easier as the texture automatically wraps around the object. If UV's needed on a NURB object it is the best to convert (modify- convert- from NURBS to subdivisions).

Texturing POLYGONS:

Texturing NURBS:

NURBS are very smooth surfaces where the texture nicely wraps around, so they don't need some special treatment when UV mapped.But this can be also a problem when we want some more defined texturing of different parts of the same object. To do so e need to convert them to Subdivisions, which have the same texturing options as Polygon and at the same time kept NURB's characteristics (the way light hits them is very smooth).

Texturing SUBDIVISIONS:

As one might notice the fish is already rigged (by Mohammed Warsame), which usually wouldn't allow us any incisions into the mesh, especially not uv mapping, but if this is done already, then it does not matter when the texture is attached.

It was a really hard job to find the best way of texturing these 3D models without loosing subtle grading quality of ramps and just the right amount of glow that I assgned to the objects right after they were being made. They looked so nicely, that I really wanted to keep them, so I had to find the solution which would include these plus assgning the brand new paper textures to the objects.

This is the bomb city that is just simply ramped:

I tried out how it looks if I attach one single paper texture as we wanted to do in the first place.

Final (after finding the right solution):

But the outcome wasn't satisfiable, so I decided to include some drawing also into the texture of paper origami backgrounds, so I preserve continuity. This is a really long procedure as I have to print out each uv snapshot in a very high resolution (1024 by 1024 dpi- so bigger than A3) and finally- DRAW on every each one of them! When these were assigned to objects...they again didn't really satisfied my expectations as the resolution was still low, although I draw them enormous. They were also keep crushing Maya, no matter how small I made them.

It seemed that assigning hand drawn textures will be easy, but everytime I tried to assign new texture it collapsed Maya, so I tried out some new approaches to texturing:

(Take into the account that we would like to keep ramps, glows and lighting effects from Maya on our objects + give them papery look).

For generating origami paper textures I sometimes this cool Photoshop plug-in (called IMAGE SYNTH) which makes pattern out of a chosen part:

I FOUND 3 SOLUTIONS TO OUR PROBLEM:

1. LAYERED SHADER

There is a possibility of LAYERED SHADER, when you can actually layer different textures one on top of another (for instance ramp on top of drawing and paper bump map).

THE PROBLEM: I would like to keep those beautiful ramps and glows at 100% and also the new under-layer paper texture at 100% strength, but with layered texturing this isn't possible. Each one takes a percentage of the whole.

2. EXPORTING FROM MAYA AS .OBJ FILE(object file, which is recognised by most of 3D software), IMPORTING INTO PHOTOSHOP CS4 AS A 3D OBJECT.

It is also possible to import the object directly into After Effects, but this extremely slow down 3D camera.

PROBLEM: This tool is amazing an it is a miracle to actually have an option of dealing with 3D object in 2D software. You can actually paint on the texture straight away. But the problem is that this option i still in the process of development and it does not allow importing NURBS. When imported, they re badly deformed. ALSO another problem is that any texturing done in Maya with it's default textures (ramps for instance) is here lost and needs to be redone.

3. CREATING A PSD NETWORK.

This is a great option offering direct response from Photoshop. The object is connected in a network and all the texturing aspects (like bumpmap, transparency, colour,... depends what you choose to be accessible from a list) can be quickly altered in Photoshop and simply updated in Maya with clicking on "update PSD network" . This option is great for someone who would like to have more control over the texture.
