Week 13 - Bump Maps, changes to the Texturing and test Rendering

Last week i created the textures for my model and assigned them to my character. One thing i wasnt really happy with last week was the design of the eyes, This week i tweaked and redesigned the eyes to look more imposing and better looking. I am far more happier with this set of eyes, than the previous ones, even just for the quality of them ,but i feel that they do add a new something to the character, and make her look more alive. I feel that they will look even better under the right lighing


I also tweaked the boots, and gave them a slight colour change, so they do in fact look like a separate entity to the Jeans.
Once i had finished with the textures i began looking at adding bump maps to my model. to do this i took my PSD of my textures, and then downloaded a plug-in developed my Nvidia (the producers of mental ray) that auto creates Bump maps for me. Once i had created a bump map with this plug-in, i bumped up the contrast and de-saturated a version. i found that the B-W bump map didn't work as well as the original bump map, so i reverted back to the original after some tests.
To add my bump maps, i added a bump map file to the original texture file in the hypershader, and then added my Bump map to the BM file, and then adjusted the textures to look appropriate for the desired material, Below are some examples of the Bump map.

The Unwrap tool shows up in green when cutting the UV's i tried to emulate real life as much possible, by following really life seams on clothing, like under the arms and around the sleeves etc

You select the seams you want to cut you select with the edge tool, and then select the add borders tool and it will cut the seams in the UV editor.


My Black and white bump map. i found that this map didnt work quite as well as the Blue bump map i produced following the tutorial linked below so i reverted back to the Blue Bump map as seem below.







Once the bump maps were in place i did some test renders, I exported my model as an obj. and then re-imported my model back into Maya. this seemed to fix the month old problem i have had of being unable to work on my model at home. However, my Maya on my PC, did not have the Arnold Render , so i tested my renders on the regular Maya hardware, which does not render my model in smooth mesh. But this wasn't really a problem yet, as i just wanted to see how the bump maps had come out along with the other textures.


Here are my initial renders with the basic Maya Renderer, while i have no included any lighting yet so that is why the images are currently so dark, i just wanted to test to see how the model looked when rendered. 


Im really happy with how the model has progressed, the bump maps really add a sense of professionalism to the model. Next week i plan to add the lighting and complete my Project.

Week 5 - Building the Jumper.

Image
With the completion of the jeans i then moved onto the jumper. i extruded the top and bottom of the jumper to create the edges, and in addition to that, also created rolled up sleeves. A jumper is generally loose to i cut down on the amount of definition on the breast area, as it wouldn't really form fit onto the body like a tight shirt would. With the jumper, soften a lot of the curved, to give the illusion of a big think jumper, i also widened the area of the neck so when the time came i could extrude of the shirt the is underneath the jumper, like in the character design, i thought about  building the shirt as an entirely separate piece, however, this would mean i would layer two things on top of one another, which could risk overlap of geometry and would also increase the size of my Maya folder. Let alone just mean i would have to spend more time on my model than i would otherwise, so the idea was scrapped.  Once the jumper was done, which took a lot less time t...

Week 4 - Continuation of Torso build

Image
The Model with less Subdivisions This week i continued with my model build, adding more subdivisions and edge loops to stylise my body into the character im creating. I constantly keep trying to keep all my work in quads, especially at this early stage of development. I added edge loops and subdivided my model to give more form to my model, that included puffing up the chest, opening up the legs and giving the illusion of the hips and muscles in extremities (calves and shoulder muscles) Once i was happy with how the body was beginning to look i cut the body in half, and used the tool duplicate special to mirror the other side of the body, by doing this the body became symmetrical and also everything i did on one side of the body was then repeated on the other side of the body making my life a lot easier when building the body.  Once i had Duplicate Specialised my model i continued to subdividing until i was happy with how it looked Once the body was modelle...
