I’m new to the world of modelling and VFX and i found Sketchfab after seeing it recommended on Grant Abbit’s youtube channel.
Seems like a really amazing learning resource (and much more besides, i’m sure!).
A couple of quick questions: when i inspect a model, am i seeing everything that went into creating that model? Or can people decide to hold back certain information? (i would imagine not every artist wants to share their inner workings if they took years to develop a certain technique).
Also, when i inspect certain models, they’re smoother than the wireframe, so there must be some kind of “smoothing” going on inside the Sketchfab engine? Or is that smoothing rendered?
In fact this whole smoothing thing is pretty baffling to me.
For example, if i create an object in Blender and subdivide it 7 times, to get an ultra-smooth shape, my computer will fall weeping to it’s knees.
But if i subdivide a couple of times, then apply smoothing, no problem. How is it possible? The computer must, in some way, be subdividing a lot to create the smoothness? Or is it an optical illusion, kinda like a normal map?
And lastly, if one buys a model on Sketchfab, does one always get everything one needs to exactly re-create that model including materials (presuming you have the right software to import it)?
