As the full-time 3D designer at Sphero, I have worked closely with the packaging team to help concept and create assets for final production. Sometimes the renders are merely for internal use to get buy off from higher powers other times they are meant to serve as production examples for printers.
When creating product renders, I work very closely with engineers and ID teams to ensure the image is accurate to what the final product will look like as I often create them before prototypes are even made. This means opening rough CAD files, exporting them to C4D then manipulating the model if needed. From there I read countless pages of CMFs to make sure all parts are textured appropriately.
After these models are complete, I am able to assist the marketing team in creating specific renders for print and digital materials.
Some of the toughest renders I've had to create involve transparent materials. They take a long time to preview then to get accurate.
Star Wars, yay!
Unwrapping objects is never fun but someone has to do it.
