Setting up HDRI file

- [Instructor] In this chapter, we will finalize the lighting, set up the VRay renderer, prepare the render passes, and then finally composite the render passes inside Photoshop. So off the recording, I have basically gathered these objects and created a composition. Let me just quickly take you through my composition. I will press P on my keyboard to go to perspective viewport and maximize my viewport. I will close this material editor down. And let me show you how I have basically gathered these objects. So I have copied this piece over here, the slice, and create a copy of that. Also, I have attached this leaf to this bud part over here, created another copy here and here. And one thing I must mention is that on these leaves I have gone ahead and applied bend modifier, to give them different shapes in order to add a bit more realism. So you can see that this one is on the y-axis and then this bend is on the x-axis with a different angle. So you can also apply bend and test different shapes. Also, I have created this camera. And what I did was I chose a view in my perspective viewport, and then pressed Ctrl + C and that will create a physical camera. And if you press Shift + F, that will bring the safe frames. And the safe frame will help give you the exact view that you are going to get in the final render. I will press Alt + W again, and I will show you that we still have those two lights. Now the first thing I'm going to do is quickly set up an HDRI file. But before that, let's just quickly render the scene out by pressing Shift + Q and see the result. With this I can see that the light is from a good direction and I'm getting these reflections on my bottle. The light is likely less than I am expecting, so we'll have to bump up the light. And we don't have any reflections in here, so let's just quickly add an HDRI file. I'll press escape to stop the rendering process and I will close this down. I will press M on my keyboard to bring the material editor. I will choose an empty slot, click on the Standard button. I will look for the VRay material, double-click that. And I'm going to click on the small box in front of Diffuse. This time I'm going to scroll down and look for VRayHDRI, double-click that. I will click on this button over here, and locate the HDRI file. Now if you have access to the SSIS files, you need to locate the link.txt file. I have provided the link to this file. I will not be providing this file in the Texture folder, because I may not have the permission to redistribute that. But you can download that from the link that is given, in the text file, or alternatively, you can use any HDRI file that you want. Now hit Open, and open the HDRI file. One other thing I need to mention here is, if you are using exactly the same HDRI file, you would see that the original file is not blurred. And I have basically blurred this file in Photoshop, because I don't want those minor details to be visible on the glass and bottle surface. Instead I just want the reflection to be visible, so I have blurred this out. And you can do that as well. And one other thing I'm going to do here is that, from this Mapping type, I will choose Spherical. Then I will zoom out, choose my VRay dome light. And I'm going to scroll down, under the Texture I will change the resolution to 2048, hit enter. And then I will click on this, hold my mouse button, drag that and drop it here. Make sure that Instance is chosen and hit OK. Also, make sure that the Invisible is unchecked, because if it's invisible, you will not be able to see the effect on these glasses, the reflection will not be visible. So I'm going to hit Invisible. So basically, the reflections are visible on this bottle surface and on this glass as well. I'm going to render this out once again by pressing Shift + Q, quick render, to see the result. And the HDRI file is added. I don't see much of reflections, so we'll be adjusting the materials as well. I'm going to press escape to quit the rendering. And I will bump the multiplier here to eight. Let's just quickly render that out once again, pressing Shift + Q, and it's way too high. But we're going to adjust that side by side so we can bring that down again. I'm going to press escape once again. One thing I must mention here is that following exactly the same values may not give you exactly the same result, because there are other parameters that the lighting may depend on, such as the light size. If you're using a very large light in here, with different length and width, you may come across different results. So you may need to experiment and get something close to what you are desiring. Now in order to get some really nice results, we need to make some changes to the VRay render setup dialog box. So in the next video, we're going to set up the VRay renderer.
