Week 5
Week 5 has been a fairly relaxed week. There was no intensive research or amazingly difficult modelling. This was the week to create a mock up of my temple. This is so I'm able to have a working shape of my temple within my engine build to give a better sense of how the project is coming along. To re-organize the minds clutter. In principle the full mock up model looks clean and pretty. However its 150 thousand polygons. Which is a tremendous amount, so I'll have to cut down on the amount of polygons and also find a way to cull and LOD this building to not take away from its impact.

The modelling process was fairly complex as stated in my previous post. Luckily due to the way Chinese culture builds a lot of the assets can be duplicated and placed. Also allowing for multiple objects to share identical UVs. This means I can limit the amount of draw calls to roughly 4 for each tier of the building. I would estimate for the entirety of the exterior I'll need roughly 15 draw calls. Which is a lot but compared to the possible amount in respect to how many models are within this mock up it could be peaking to 70.
After creating the mockup, I applied the first tier (being the only fully complete one) into my engine to see what it looks like with the cel-shader applied. I used smoothing groups to eliminate outlines where I did not want them on my model applied by the cel-shader. This worked exactly how i planned it.
Other than the implementation of my first tier I've played around with lesser aspects of my project. Such as the grass terrain, collision being added to the temple assets, the bamboo Forrest, so on and so forth. The key points to highlight here are that I still haven't worked out how to implement a low polygon and aesthetically pleasing bamboo forest. The grass texture is UE4's built in texture so I need to replace this, and I've removed normal maps on the terrain texture until I fully work out how to get it functional.
There are some possible Ideas floating around my head such as a lake in front that has large statues of Koi, Mythical beasts, fountains with water particle effects, water shaders etc. This is all for a later stage of development.
Week Four Update!
From two weeks ago until now there has been no major changes to the project. Its been simple and straight forward progress with the modelling. I've created a few new models and implemented them within my unreal engine build. The most challenging aspect of modelling throughout the past two weeks was creating the roof of the temple. There's a saying that the Asian architecture is the most complex yet aesthetically simple way of building there is. This is an understatement. I thought that because it's 3D modelling and not replicating their builds in real life not having to slot beams together and calculate all the physics that it would be easy. It would just be building the same shape, however it turns out regardless of all those missing factors simply just replicating the shape is very challenging but extremely rewarding.
This is the Temple build as it stands within a MAX file. I built the temple mock up within max because its easier to change variables rather than implementing it into unreal and trying to re-import every time.
So far I'm happy with the first floor layout. However this being a very early mock up there is many integral variations i want to implement into this build. For examples the left and right walls perpendicular to the front entrance will have buildings in-front of them. There will be a smaller replication of the ground floor attached to the ground floors roof. (Like layering, as seen in common temple photos). So on and so forth. This is a very rudimental mock up.

Week Two
Terrain Textures & Cel-Shading
After creating the FMP proposal, I can now begin the modelling process. Originally I was going to use photo realistic textures and then air brush & photo process them to create similar lighting conditions on each texture, then use them to create a photo realistic environment. However on second thoughts this shows less skill and is relatively easy to produce. Instead I've decided to use the vector painting system within unreal & my own hand painted and generated seamless textures to create my terrain with.
To start off this process I've began by creating a seamless wood chip texture. This is my process of how I've accomplished this to what i believe is a believable result. First off, I created a brush that resembled a wood chip.
After creating this brush, it was relatively easy to then reproduce a texture from a reference by layering different sizes and colors of the stamped brush. This creates the illusion of depth as if wood chips lay beneath the others.

You can easily tell this is a seamless texture. However this texture is not of main focus and will be nearly out of sight. The ins and outs of perfecting it is not necessary. If from a distance can you still see the repeating texture then I will have to re-do it.
Cel-Shading
Cel-Shading is a way to create cartoony-look-a-like models through texture. It allows for an stlye to be applied within engine without recreating it through use of textures and 3rd party software. This increases work flow immensely and also creates an effective look art style. Within UE4 theres an advanced post-processing system built in. Cel-shading works with the post processing so it encompasses everything in the build. Meaning you have to create custom Cel-shading blueprints for the two tone shading effect. Like so -
A basic rundown of this complex looking blueprint is that it takes the light rendering before its cast, limits it down to a simple if statement, and applies a colour tint to the light rendering. For example, if the light intensity is greater than whatever the boundary for a shadow value is, it condenses the range of light above it into a single shade with a colour tint you can choose to create a two coloured lighting system.
The black outline blue print, (the one on the left) is alot more complex and to explain but less important so I'll link my reference videos that explain instead and along with the paste bin for the blueprint of the outline shader that i copied.

The effect is striking, quick and easy to use after the initial set up.The use of the technique was mainly inspired by games such as borderlands.
Week One - The Proposal
Week One of the FMP module has started. The opening lesson rotated around the 3rd years proposal of their FMP. Each person in turn, communicating their ideas and planning surrounding their visions of their largest project yet. After the basic introduction my tutor offered me feedback on my planning I did before the semester started. Overall, the feedback he gave me was positive with a drawbacks. The main aspect of which was the size to detail ratio my concepts displayed. He believed it to be too much to do in too little time time. Taking his feedback on board I've decided to downscale the size of my temple and strip away detail on the inside but keep the level of detail on the outside structures for the initial impact.
Another idea my tutor suggested was to create a linear path through the starting point to the temple using light blocking out the surrounding world in a mountain pass/or bamboo forest (which is the most probable idea for me considering the theme). This limits the wasted time on the open ground terrain i currently have in my concepts that would of need not only a lot of time to fill in. But also a high amount of polygons and resources in an already detailed world.
