A mug I like (off-topic)

Greetings, it's vacations and I got bored so I decided to do some experimentation with Blender Cycles. This does not mean I have any plans for making sentinel models at the moment, but I wanted to let people know I haven't left 3D modelling completely.




First the base mesh. Basic geometry was polished with some loop cuts, subsurface modifier and vertex smoothing.

Next up is the material, created mixing a glass shader and a transparent shader.

Then I changed the point light to a hemi one, but I got rid of that later. It does look nicer, though. Also disabled the caustics because they were slowing the previews down.

As you might have noticed the glass is quite gray inside, this happens because the glass is casting a shadow on top of the other glass, so it gets darkened. This was fixed using nodes with some sort of condition. Basically, if a shadow is cast on the glass, the shadow ignores the glass.

The little figures behind are just a cube and a sphere to make sure the glass was behaving properly.

Finally, the proportions were polished, lighting was improved with a bigger and stronger lamp, the camera adjusted to match the real picture and causics were enabled.

There are darker reflections in the 3D model because well, there isn't a lot of ambient light like there is in real life, but adding that was going to be a bigger effort and I wasn't sure if it was going to work well.

I always found it amazing how you can get rudimentary meshes to look real just by playing around with the materials tab. I seriously can't tell the difference between that and a real mug just by looking at it.

Yeah, I was impressed how small changes modified the model, to the point where it looked realistic.

From "that's a 3D mug" to "oh you cleaned the mug? no it's a 3D model".
