Learn how to add and edit lighting to give specific lighting and shadow effects as required.
- [Instructor] Now let's take a more in-depth look at some of our lighting and rendering options. Again, I'll just navigate to my Render tab, which really has all of my rendering and lighting functions within it. And first maybe I'll take a look at the Mode drop-down and I'll change this from Smooth with Outline, as it is currently, which is showing me my tangent edges, and maybe I'll change this to just Smooth. So I'm no longer seeing any tangent edges and maybe making my product look a little more realistic.
In addition to this maybe I'll want to show some of the internal electronics of my product. So I can hide the top half of my enclosure. So I'll grab the top of the enclosure, navigate over to Properties, and again, we saw how we can change the Opacity here, and I'm just going to throw this all the way down to 0 to show the internal electronics. Now let's take a look at a few lighting options.
So I have a couple of different lighting options I can play around with here. We have another Shadows option. This Shadow actually applies shadows on top of my existing products, whereas the other Shadow throws shadows onto the ground. I can also throw on Ambient Occlusion, or Glow as needed. In this case, maybe I'll just turn off Glow and leave the other two. And then lastly we'll take a look at creating some custom lighting.
So right over here I have a few pre-created lighting modes. So I can hit my Mode drop-down, and I have a number of different lightings that are already pre-defined as defaults within Composer. So I can jump through a couple of these and see how it might change my image. And maybe see if I'm happy with any of these. But if I'm not I can actually go to Custom and create my own lighting scheme as well. So now that I've gone into Custom I can create whichever lights I'd like.
So I can hit my Create drop-down and add a whole bunch of different lighting options as required. So in this case, maybe I'll just throw in some Directional Lights above my product pointing down towards. So it's going to change not only the lighting, but how the shadows will look as well. So I'll just grab Directional Light and maybe I'll zoom out slightly here. And I'm going to try to place my lighting somewhere above my product, and maybe pointing down towards the center of my product.
What's also nice here I can add as many lights as I'd like. And I can fine-tune these as required. So lighting options, I'm just running through this real quick here, but you can spend seconds, minutes, or hours fine-tuning your lighting options. So now I can space these lights within my 3D environment wherever I feel best. I can change their density, I can make whatever changes I may like to fine-tune my lighting options.
So here let's just make some slight adjustments. Maybe I can click and drag, you can see, to move my lighting as required. And see how it will affect or change my product. Once I'm happy with my fine-tuning, these lights are collaborative actors as well, so I can, again, grab each of these and take a look at some properties I might have available as well. So I have a few different lighting Properties, Intensity, color, and so on. So if I want to change the color slightly, maybe give it a yellowish hue, I can go into my colors, maybe I'll choose Diffuse color here, and change it to a pale yellow here.
Now it looks like it's giving a kind of pale yellow lighting onto my object and additional shadows based on the location of my lighting as well. Once I'm happy with all of these maybe I'll jump back to the Marketing View that I liked and right-click to Update my Marketing View. The final or last step might be just to output my marketing images.
And again, we've already taken a look at how to output raster images, so I can just go into my Workshops and probably for this case not so much a Technical Illustration, but more of a High Resolution Image. And I'll jump into this Workshop over on my right hand side. And just as before, I have all the same options, all the same settings, but what I might want to change here is just increase the quality slightly, or increase the resolution. So I can go into the Resolution, increase as required, so I can change the Dpi, the pixelation, the Size, or even increase the Quality slightly.
Of course, your file size will increase with that, but you might get a better looking marketing image as well. Once happy with all of my settings I can just do a Save As. Rename this and save out to whatever file type I would like and hit Save. And it should just take a second to export to there. And I'll just navigate to that directory I just saved to, and just take a look at the JPG image we just output.
So here you can see fairly quickly and fairly efficiently we can export some pretty decent looking marketing images as well using Composer.
