I've recently been working on my game modelling in my spare time, with hope of relevant work next year.
The brief: make crab tank, make painterly, make low poly.
Here is the concept, cribbed from cghub courtesy of one of Naughty Dog's concept artists.
While its quite lovely, it leaves a lot of the form of the tank to the imagination, relying on a strong silhouette to convey all it needs to. Thats fine, until you have to figure out how it might work in three dimensions, so I took the concept into Photoshop and tried to create solid shapes from each of the different parts. Also there are some crab diagrams, never know when they might be useful.
Unfortunately I went to town and ended up creating a 7gb sculpt that no longer ran properly on my desktop, weirdly my laptop has twice the amount of RAM and Griffith saved the day, I was able to export all the AO and Normal maps from there.
Then began the texturing, I was trying to go for a cross between the texture style of Journey and the messiness of the original concept. These two styles are slightly at odds due to the clean gradients of Journey and the dirty oils of the concept.
marmoset skyshop in a sale and used some of its image based lighting and shading techniques to creating a little scene with the crab tank in.
