3D Glass Dice Visual for Print Advertising

The production of the 3D Glass Dice Render Hi-resolution product visualisation, 3D rendering and post edit

I was recently ask by one of my clients, SeeThinkDo, to create a render of two 3D glass dice rolling across the ground. To be used in a print based advertising campaign.

The initial brief was to create a ‘photoreal’ visual but not ‘hyper real’. To address this request a virtual ‘physical’ camera was used where I dial in shutter speeds, iso rating and f-stop values, just as you would find on a real camera. After exploring a range of exposure types and settings I settled on a nice balance between exposure and depth of field without becoming to narrow a focal length. I also added some slight marks and scratches to the artwork of each die which was then passed through a bump channel to help break up the  specular / highlights and introduce irregularities in to the surface of the die.

The 3D glass dice are completely computer generated and the dice were modelled by me. Due to time constraints and budget I opted to use a process called ‘subsurface displacement’ to create the dots which meant that I could use a texture map rather than modelling each face of the die individually. This proved to be a prudent decision when asked to rotate some of the orientation of certain faces on the die and also to re-shuffle the layout of the faces, changing a photoshop composition in this instance is far easier and less involved than a remodel of highly detailed geometry.

Choosing the render engine Preparing for the final composite and the starting point I give myself

At an early stage I opted to use the Vray render engine for the final output as I knew the transparency of the Dice could cause issues further down the line when it became time to render had I used Cinema 4D’s built in Advanced Render or Psychical Renderer. This 3D glass dice render took around 2 hours to output from Cinema 4D at 300dpi and A4 in size. My feelings on this are that the standard C4D render times would have been considerably longer! And well, lets be honest Vray gives such lovely results effortlessly! I did spend quite a bit of time optimising the render settings making sure the sample rate was kept in the blues and greens!

The final 3D rendered image supplied to my client. Typically I will provide my client with a jpg version of the final visual, I also include the layered psd file which more often than not will include all the multipass captures from the original render output.

I often provide my expertise as a 3D support role to design agencies, producing a final render. When this is the case, I rarely get to see the final published artwork. This is a mockup I prepared, of what I believe how the ad was going to look in publication.
