Building Alliances Week 9,10,11

 Asset modelling

This week I will be focusing on starting some initial 3d models in order to get an idea of what the different details in each of the levels would look like. To start this off, I will be modelling in Maya to create the basic block out of the assets, which will then be taken into zbrush to make the models more organic to stay in theme with the rest of the game. 

To start off the modelling process for the big tree for the lungs level, I modelled the trunk of the tree, starting with a plane which I arranged into the desired shape for the trunk, I then extruded the plane upwards, scaling it inwards the higher I got. Once I had the trunk in place, I used the insert edgeloop tool in order to create more faces from which I could extrude the branches out from the main trunk. For the general shape of the branches, I used the same process as with the main trunk, scaling the branches inwards the further out they got, I also rotated the extrusions of the branches to give them a more natural look rather than them being straight branches.

With the branches in place, I started to add the alveoli clusters to the ends of the branches, in order to do this, I grouped up several spheres and scaled them depending on what I needed for each of the branches. With this block out complete, I will now send it to my group for feedback.

After sending my model for feedback, my group has said they like the model I have made, I will now model two more trees of different sizes, these will be used for variation in the level design.
Using the same methods that I used for the first tree, I made a medium and small tree model. I will now start to work on the UV map ready for texturing the model in Substance painter. In order to do this, I will use Maya's Uv editor in order to move the different sections of the model about, making sure nothing is overlapping as this would interfear with the texturing process.
Once the UV for my assets was sorted out, I exported them as an obj file ready to put imported to substance painter so that I can texture the models. In substance painter, I was looking for some more natural textures for the surface of the trees since they're based on the inside of the lungs. Eventually I decided to use the creature tongue texture for the branches and trunk of the trees, while the alvioli leaves were textured using the blue alien skin texture as this best fit the idea for the leaves. In order to apply the textures, I placed a base baked light texture on the whole model, on top of this texture I then placed the red tongue texture which covered the whole tree. In order to apply the blue texture to the leaves of the trees, I added the texture to the whole model, but then applied a black mask to the layer so I could reveal the texture only where the leaves are.
With the textures now applied to the model, I am pretty happy with how it has turned out, I will now set substance painter to render the models to see how they'd look in different lighting, as this will inform me on my lighting and colour choices for the rest of my environment assets.

Moving on from here, I will start working on the entire lungs level model, this will be used as one of the final models to give a better idea of how the game would run

Tool kit 2 3D - Character project part 2

 Case study Rafael Grassetti The first game artist I will be looking at for my case studies, is Rafael Grassetti, who is a very talented game artist working with both 2d and 3d. He has worked on a lot of major titles in the gaming industry as well as cover art for both Marvel and DC comics making him well versed within in the design industry as a whole, being able to work effectively in both 2d and 3d media. One of his most notable roles in the games industry recently is his time working on God of War as both a principle artist and art director. For the purpose of this case study, I will be focusing mainly his roles in a 3d aspect, how his 3d workflow is structured based on different models and character designs he has poseted on his artstation portfolio. One of his most recent works on his art station accounts is a character design based on the Arrakis suit from the Dune films. In his process for modelling this design, he has used both 3DS Max and Zbrush. The initial modelling pro...

Real Worlds - Part 2 Environment development

 Main building design Initial Building Designs: For my main building, I would like to design something based on real world quarry buildings and mineshafts as I feel like my game idea would be mainly taking place in a more subterranean environment with a lot of mining equipment and buildings around the world that the player is fighting in. In order to get enough ideas for my building design, I have compiled a moodboard of different real world examples of mining related buildings showing off the different kinds of systems that are a part of buildings found in quarries and mineshafts. Using the images of mineshafts and quarries, I'll start to sketch some initial ideas, starting off with sihloettes to get a general idea of the shapes that I will be using in the building design, which I will then move onto creating some more detailed designs before finishing off the design. For the initial design process, I started off with a series of different sihloettes using two building bases which...

Industry practice - Environment pieces and Project evaluation

 Asset production This week I will be starting to draw the final backgrounds for the visual novel, this will include both of the environment designs that I have made so far, and any other environments that other members of the group have designed. In order to do this, I will be following the same art style that we decided on at the start of the project in order to keep in line with the style being used for the character sprites and the UI. To start this process, I will be deciding on a colour scheme for each stage of the environments in order to properly incorporate the character sprites into the environments, even if the colours are different, having some form of overlay will allow this to happen more easily.  For the finalisation process, I will start with the most used environments over the course of the novel, finishing with the ending scenes that are only present in one part of the game. The first environment I will be finalising is the bedroom environment, as this backgr...
