The making of a commercial still part 3

This is the third part in my series “The making of a commercial still”.

Last week I created the model of the perfume bottle and this week I’m going to provide the model with materials and set up some basic lighting to see if it makes any sense.

In order to test the materials and lighting I have to render the scene. Now Blender uses two sort of rendering engines. The classic “Blender Internal” engine and the new and more sexy “Cycles”. The latter is supposed to give photo realistic results, because it emulates the way lights travels through different mediums, like glass, air, water etc. It also emulates how light reflects of off surfaces and does cool stuff like color bleeding. That’s something we photographers take for granted in real life ;-). So I choose the more sexy ‘Cycles’.

For testing purpose, I have set up a white curved backdrop and placed three virtual softboxes more or less randomly, just to provide the scene with some basic lighting.

For the materials, I used the standard Blender stuff. Nothing fancy.  So for the glass bottle I used “Glass BSDF”, for the plastic cap I used “Glossy BSDF”. And for the black ‘liquid’ I also used “Glossy BSDF”.  You can do all sorts of fancy stuff with these materials, but for now I use the “plain right out of the box” options, without tweaking any parameters.

And here is the first test result:

It’s sort of okay-ish. It looks like a photo, but to me it still isn’t realistic enough. It still has that ‘CGI sheen’. You don’t know what it is, but you can tell that something’s wrong.

I’ve also noticed that I didn’t properly modelled the bottle. The corners are too round and the glass is still to ‘perfect’, so I have to dirty it up a little. I have to start tweaking the parameters now and pay a lot more attention to lighting the bottle. And last but not least, I will try out some different rendering engines (outside of Blender) to see if they come up with different or better results.

Stay tuned for the next instalment of this experiment….
