Week 8

we had a guest lecturer today, Lisa Rye, who took us through 3D modelling workflows. 

she began by showing us how UV unwrapping works - projection unwrapping is when the model's UVs are determined based on the camera angle, and is primarily used for 2D although it is rare. 

it is important at this stage to consider what materials you want to apply to the model, so as to ensure that the shells are pointing the right way. For example, if an object is wooden, the shells need to be arranged properly so that the grain flows accurately. 

'padding' is the space between shells in a UV map - it is useful to have an increased padding size when unwrapping for a low-res texture renderer, e.g. mobile games 

always make sure the scale is set to 1 before and after unwrapping! 

next, she taught us how Substance 3D Sampler works for texturing from an image 

atlases (e.g. a series of leaves) can be imported into Unity and sliced up to be used as textures
