If you are looking to release a new range of clothes or e commerce item. It may be beneficial for you to get some 3d rendering done. You can either contact a specialist like Render Vision OR learn to do this yourself if you are are planning to do it a lot.
The way you produce your product renders could be quite different depending on the company you are working for, the demands of your client and the software you use, however, the following tutorial broadly shows the steps you would take from start to finish in order to develop a great product render
1 Sketch it out on paper
While it might seem a bit archaic to some tech heads out there, we highly recommend beginning the process by sketching out your design on paper. While not 100% necessary, doing these sketches to scale and using proper tools to get your straight edges and angels will help a lot when you get around to generating computer images. It might be a good idea to start with a top down view, and then sketch up a drawing showing it from all sides.
2 Choosing Your Software
When it comes to mastering the art of 3D rendering and creating a real, quality product you need the assistance of a 3D rendering software. You will find that there are a variety of tools and software available for your needs. Of course, not every software is tailor-made for the beginner, but some offer tutorials and the like. This can be extremely helpful. SketchUp is one such product that was specifically designed with the beginner in mind. In fact, the program can be downloaded for absolutely nothing, so you can get started right away. When you combine this with the easy to understand toolbars, this software is a beginner’s dream.
3 Deciding What You Want To Do
3D rendering can be used in a variety of different fields. For instance, it can be used in video games, movies, and even TV shows. There is probably a good chance that you already have at least some ideal of how you want to apply your skills. Animated movies can take anywhere from 3 to 5 years to create, whereas the typical TV show might only take around a year due to the shorter production times. Regardless, the task is no small one, and working as a 3D rendering artist on huge projects like Toy Story or Dr. Who can be extremely rewarding.
4 Create an ‘environment object’
It’s time to boot up your computer and start developing the 3D digital image. Initially, you’ll want to create what is known as an ‘environment object’, which is basically creating a digital room to display your product in. The reason for this is that, in order to look good, your product needs not only good lighting, but good lighting reflections from its surroundings, and the environment object will help with this. There are a few standard shapes that designers use, and choosing the right one to use will depend on the product you are creating and the kind of image you are going for.
5 Build your product
Now you can start building your product and place it somewhere on the environment object. Generally, most artists would recommend keeping the wireframe as simple as possible to start with; details and extra features can easily be added later, but it is very important to focus on the fundamental aspects of the design that will make it stand out. Furthermore, you don’t want to waste hours working on small features that may be cut from the final design. Once the wireframes are done, you can render a simple surface if you want. Remember to check your model from lots of different angles and perspectives, including isometric views, to make sure it looks great.
6 Add in your lighting
Now that the object is ready, we need to get our lighting correct in order to make it look realistic. You’ll want a few different light sources to get the best, most photo-realistic effects, and real life photo shoots will have multiple lighting rigs as well as the normal room lights and possibly windows. You’ll want a light to illuminate the whole rooms, similar to a skylight, and also some lights to highlight specific parts of the product. Getting the lighting correct is a long process which will require a lot of work, but your software should have built in tools to help you with this. Also, pay careful attention to the shadows; too much shadow can make your render look ugly. Again, test the lighting and shadows from many different angles to make sure everything looks good.
7. The Final Render
Once all this is done, it’s time to make a final rendering, adding in the surfaces that you want on your model. When coming to make the final render, remember to zoom in on the object; a smaller render will be much quicker.
8 Post Processing
If the render is finished and it still looks a bit rubbish, don’t worry coz you’re still far from finished. Drop your render into Photoshop and get started on your post processing. You can start out by optimizing your workflow; delete everything superfluous or unnecessary and adjust the spacing and panels so you have the largest image possible. After saving a copy of your image just in case, start with layer and curve adjustments. Next, it’s time to get your colours and lights corrected. Color filters, vignetting, gradients and a bit of lens flair do wonders for getting rid of that ‘computer-ness’ of a raw render. Finally, you want to get those subtle little flourishes that make all the difference such as color blending, tints and level adjustments.
9 Quality control
We all know that feeling of having just submitted a product and being desperate to submit it so you don’t have to worry about it ever again, but that feeling is your worst enemy. Once you are done, take a break. Ideally, get a night’s sleep before looking at it again, but even an hour away from the computer will help you get some distance and refocus on your reviewing your work. Be as neutral as you can, and fine comb your image to iron out any problems you find. Once you feel you’ve done as much as you can, have a colleague or your supervisor look it over, and take any criticism or suggestions seriously and objectively. Once any additional changes have been made, congratulations! Your product visualization is done.
