Adding lighting

From: SolidWorks Rendering with PhotoView 360

Video: Adding lighting

Both solid works and photo you have lights that we can adjust the brightness, size, location and harshness of the light source. By default, each scene has lights that are active, and generally these are different from the lights, that used in the solid works view. We can add, adjust, and remove lights as needed to light a scene. Just like photography we will normally have a key light, fill light, and maybe some ambient light sources. We can then add in other lights to highlight our parts and add in special looks. To get started let's go ahead and look at the scene here. We're starting from the point we left off in the last movie.

Adding lighting

Both solid works and photo you have lights that we can adjust the brightness, size, location and harshness of the light source. By default, each scene has lights that are active, and generally these are different from the lights, that used in the solid works view. We can add, adjust, and remove lights as needed to light a scene. Just like photography we will normally have a key light, fill light, and maybe some ambient light sources. We can then add in other lights to highlight our parts and add in special looks. To get started let's go ahead and look at the scene here. We're starting from the point we left off in the last movie.

And you can see here that if I come up here under appearances on the beach ball, the last icon here under Display Manager. Notice I've got the materials or appearances here. I've got a decasl tab, and at the last one here is the View Scene Lights and Camera tab. So underneath the scene you can see what's being applied. I've got a environment, a background. Under the lights you can see, I have a scene illumination. Have an ambient light source and I have two directional lights. So if I right click on this light icon here at the top, I can show the lights if I do that, you can see here's my light sources available.

If I right click on it again, I can edit the lights I can add directional lights spotlights point lights. And anyone of those things. It can also click on anyone of these individual lights and changed it. For instance this direction number five, I click on it, highlights in blue over here in the window, and if I right click, notice that I can adjust the light. If i right click, it says edit directional light and notice that as soon as I do that, I can click on this light here, I can more it around. And that'll adjust how the light lights in the scene. And you can see, some little highlights as it moves around the scene how shadows and things will start changing as I move that light source.

I can also adjust how much ambient light is available here, the brightness of the light. How it effects the model. So you can just really drag these sliders around in the model, to see what happens. This is also the basic view, this is how we're seeing it inside (INAUDIBLE). This is not the same as inside a photo view. So if you click on the Basics Tab, you can also click over here on Photo View. Notice it says on in solid works. If I turn that off, you can see it's a completely different view. If I go to photo view, I want to turn that same light on in photo view and now will show up in the photo view integrated preview or preview window.

There's two different options for looking at the previews, I prefer generally the preview window because it just pops up on the screen in the small box. Or if you have dual monitors you can put that on in the secondary monitor, and you an pause and reset is as needed to see what's going to happen in your model. The other option if I close that, I go to integrated preview it turns your entire view into the preview. The only problem with this is it seems to me it takes a little bit longer for those representations to happen, as I move the model around. I'm always in that same view so, it does seem to take a little bit longer because its constantly rendering your entire screen versus a small box.

But really it's up to you, to see how you want to apply these and how you want it to look when it finally renders out. Once you have it, I can click on those icons because I'm still editing that light. Notice if I move it around, give it a second to refresh. Spin around here a couple of different options here, see how it looks. I can also bring that brightness of the light down if I need to. I can add in shadows if I want to. I can soften the shadow by dragging this a little bit, you can see just kind of behind the light there, some of the shadowing that's kind of changing as I adjust it.

I can even adjust the quality of the shadows, see what's going to happen there. When you're happy with that light and it looks good, go ahead and click OK. And there you go. Notice, also over here in the icons, there's two icons in a row. So basically it'll be your first icon which means, it's going to be on in Photoshop. And the second one's going to be on in Photo V 360. So I can right click on those and turn those on or off here. So if I say on in photo view. Notice the icon changes if I go back to it, and I say Off on Photo View, the icon turns to gray. So you can turn those lights on or off, depending on the situation.

Also, ambient light, we can adjust that as well, right? So I can show the light itself. I can edit the light. Bring up the ambient color, how much light's actually being put on the scene. And bring that down. I can also edit the color, so if I wanted to choose this and make it a red light, for instance. I'm going to put it on in Solid Works, and that's really only changing it in Solid Works, not in the photo view window. So, in Photo View, depending on what we have, I'm going to go ahead and in-grade a preview. Turn that off. Now in Solid Works, notice that red light's really effecting what we have.

So if I say. Edit light, My Color. If I go back to white light, it comes back on. On in Solidworks, off in Solidworks. And how much light's actually being cast in the scene, I can bump that up or down, and click OK. So anyways, there's a lot of things to play with as far as the lighting of a scene. You can add lights, remove lights, you can move them around. If I want to add a light, which is the next thing I want to do, is right click here, and say, Add a Spotlight, or Directional Light, or Point Light. I'm going to try Point Light out.

That's going to be similar to like a sun, like a big light, really far away. going to kind of cast a lot of light on the scene. Click OK. And notice where that little point is. As I move it closer to the model, you can see it's got a little point, as I move it further away, it kind of spreads out that amount of light. And these are really handy if you're going to try to just like light one little area there. You need some extra light inside somewhere. That is kind of not rendering the right way. Add the point wherever you need to. You can adjust where it is in XYZ coordinates. The brightness, the specularity, and the ambient light as well.

So a lot of things we can play with when we're dealing with lights getting that look you want. Like with most photography, its the lighting that makes all the difference solid works and photo view provide a powerful set of tools to light a scene. So let's add in some lights and get ready to make some amazing renderings.
