Join Dave Schultze for an in-depth discussion in this video Strategies for "entourage", part of Rhino and V-Ray: Architectural Rendering.
- In this video we discuss the strategies for Entourage which is elements used for scale, context, or just generally cool decoration. So imagine how boring your rendering would be without any people or trees or grass. You don't want this to look like there was a war and everyone left town. I've broken these down into three basic ways we can add Entourage elements. I'm gonna go through these and list pros and cons of each. First up is 3D Geometry. This example we're looking at a 3D model of a small girl with some very high resolution texture maps.
So the pros are obvious. This looks great, we're getting good shadows on her and her in the scene as well as reflections going both ways. The cons and these are kind of minor as you will have bigger files and slightly slower rendering. The reality though is this is not a big deal anymore. Computers are much faster and V-Ray is more efficient with each and every version. The second method is 2D which is sometimes nicknamed "The Cardboard Cutout". So the pros of this technique... One of the pros its a little bit faster to render.
Additionally it's got a much smaller imprint on the file size and it can look pretty nice. The cons are that it looks really bad from the wrong angle or high angles. The shadows can sometimes get really messed up and you typically have to move these guys to face the camera. You can see the one guy on the right. He's perfectly aligned so that will probably render okay. However the 2D guy on the left has been angled a little bit too much so we're gonna have kind of a distortion there. Lets check out the rendering. The 2D or Cardboad Cutout Technique used to be much more critical when the technology was less advanced.
However I don't recommend it and we're not gonna cover this at all in the remainder of the course. The third and final method to get geometry in your scene is actually no geometry. So what does that mean? Photoshop! This is also referred to as Post Processing or just Post for short. The huge advantage here the big pro is it takes no extra time to render. We get total control over placement of elements, and this can be much quicker to make changes. The cons will be is it can take a little more time if you start getting too many changes.
That's typically pretty minor. In this example I've rendered the scene. without the channels we have no sky at all! That gives me far more control here in Photoshop when I go to the next slide and now I can pop in any type of clouds or sky that I want and move them around. A great example of the benefits here is you can imagine if you'd spent many hours rendering a single scene. And then were asked to remove some trees or clouds or whatever so that is not a problem at all if you're in Photoshop.
You can actually just turn those layers off, re-save the file and you're done. So this can save greatly on re-rendering many times. Final tip I'll share is to keep things organized and on separate layers. So if you look to my layer pallet you can see that I've kept the building element separate from all the entourage. Notice that the trees and people and even the furnishings inside are separated. This can really help you focus on the building design and get done quicker. I typically keep all the Entourage layers turned off so they don't get in my way and I can make maximum speed.
So basically I'm saying you don't really need the entourage until the very end when you're ready to render. These are the basic strategy I use and recommend. For most cases you can also use a mixture of 3D objects and Post Processing. There's no absolute rules except for whatever works best for you and your deadlines.
- Setting up your system
- Understanding the settings, software, and process
- Lighting the scene
- Tweaking exposure
- Rendering with architectural glass, masonry, and concrete
- Making realistic grass and trees
- Creating depth of field
- Compositing from 3D to 2D
