An environment channel can also be added to material to simulate reflection. We're in chapter 8 of 3C 4D. And, if you want to follow along, you can open that, too. I've created a metallic material here. If I double-click to open up the Material Editor. I can add an environment channel. Now I've already added that here. You'll see I've added the environment channel. At the moment it's just using a white color for the environment. And you can adjust the brightness of that here using this slider. But at the moment, it's not really doing anything.
So what we're going to do is load a texture. So I'm going to load the same picture that I used for the reflection channel, the instrumental video9.jpg, which is a frame from the video that I'm going to have playing in the background in Aftereffects. And you can see immediately that, that video or that image is actually being reflected onto the metallic surface of my robot. Now I can choose blending modes I could choose add or normal or multiply or subtract.
I'm going to leave it on normal I'm going to bring the mix strength. Down a little bit. Okay, so, we don't want to have too much of it in there. You can also adjust the brightness as well. So, if you find that's too bright, you can bring the brightness of that down a little bit. But it's nice to have a little bit of the image that's going to be surrounding your scene reflected onto the robots. There are some other options in here, you have options for sampling, you can choose different ways of wrapping the image around the environment.
We're going to stick with the default. There are also blur offset and blur scale values there, but for now I'm just going to use mixed strength and brightness values just to adjust my image. So I'm going to bring down mixed strength. To about 70%. In fact I'm going to have to adjust the brightness a little bit to compensate for my mix strength. Now, if you were using multiply mode, you wouldn't have that problem of it being too light. So maybe jump back to multiply mode, and that helps us compensate for that problem.
So about 75 and 90% should be enough just to give a hint. Of color onto the surfaces of my robots.
