Let’s render the idea… | part 2


The software that we talked about last time, Adobe Photoshop, is perfect if we’re constructing a rendering for wallpaper… if you’ve tried it out, you’ll have understood that all you need to do is some good quality cutting and pasting with plenty of attention paid to getting scale and perspective to get it looking right, but, if you’ve tried adding your designs to a sofa, or a bed, with all those folds and shapes, you’ll have realized that the job can be a little complex and that the result doesn’t always hit the mark… so, let’s take a step into the world of 3D modelling!

My favourite road into the 3D world is with another software from the Adobe suite, called, very aptly, ‘Dimension’ (DN). One little reason that I like it so much is that it’s ‘free’ with my Adobe subscription 🙂 …so check your Adobe account, and maybe it’s included in your subscription too!

Special ingredients

First of all, the bed or the sofa, or whatever you want your design to go on has to be what’s called a 3D model to be able to use DN.

Unless you’re a real computer buff, making a 3D model is probably going to be out of your ballpark, so the first thing you’ll need to do is find one of these models on the web. You need to search for a particular type of file that ends with the extension OBJ, so put that into the search engine, for example, ‘sofa OBJ’.
There are plenty of them out there, some you can have free of charge, others you’ll have to pay for, but don’t forget that from just one 3D model, you are going to be able to make loads of promotional images for your designs, each one with a completely different look, thanks to the magic of working in three dimensions… Here are a couple of suggestions to go and explore:


The other important part of your rendering is the background.
Don’t forget that whatever you cover with your design in the rendering needs to be the star of the shot, so you’ll need to get pretty close to it with the rendering to show off your design… not the plain furniture or the room it’s in!
Because of this, the shot needed for the background needs to match the resolution that you are going to work with using DN. As I said in article no.1, the maximum image size for the one that you’re going to publish is the standard web-accepted 2000px by 2000px.

“Of course, there will always be those who look only at technique, who ask ‘how’, while others of a more curious nature will ask ‘why’.”

– Man Ray

Now, that’s pretty low quality when you consider your usual standards for designing, and you might want to make the rendering keeping that high standard, so you’ve got a high-quality version if you ever need it. Working in high resolution with DN means that, at the end of the rendering, it may take a long time for your computer to finalize the file, so beware.

Another thing is the subject of the shot you need to look for, which basically needs to be of an empty room or space, and don’t forget to look for images using the “creative commons” tool if you want a copyright-free freebee. Take a look at the example here, made with a background image bought from Adobe Stock, and then made into a render with an Adobe Stock sofa OBJ using Adobe Dimension: the pattern on the sofa is the focal point, the background is empty floor and empty warehouse.


So, that’s covered the bases, let’s start playing the game…you’ll enjoy this! There are some great tutorials online, so go check them out if you’re a beginner

The ones that I recommend to get you started are these two, to watch in order. They’re a comprehensible intro to the basics of the software and you’ll soon be diving in there and loving it: 


Before starting with DN, crop a copy of your background down to the area that you want to zoom in on, where your 3D object will be, keeping the original resolution in PS, then, from the top menu using -Image-Image size- take note of its measurements.
Open a new page on DN and set the format to be identical to the one you’ve just made in PS.
That’ll make sure there is no difference between the quality of the 3D object and the ground in the finished rendering. At this point drag your 3D OBJ file onto the DN page and you’re ready to add your design!

Once you’ve understood the basics, it’s going to be just like riding a bike! You’ll be able to produce real-looking renderings of any design in your collection making it even more appealing to your clients, so, have fun guys, and if you need my help here at, just get in touch!
