A landscape rendering should include details about plants, including the direction of branches or the way plant stems bend or spread. For example, some trees have branches that grow straight out.
I guess I'm looking to see how ppl photoshop grass, plants, trees into their renderings and still make them look pseudo-photorealisticIt is quick and easy way to do still images. Or if your computer is not capable of handling too many complex geometry. You may want to render building and the ground plane with vanishing point to add stuffs with PS such as trees, materials ( texture), people, etc.But if you have time to invest, search a few Youtube videos on how to do it in programs like V-ray,Thea or Max. The process is not that complicated at all actually. You may also want to look up forums for these programs, and ask questions about things you find hard to understand. You could also post your WIP to ask advice as well.
There will be some 3D snobs who tend to look down upon the practice of retouching the (raw) still images with PS. But who care? You're not a 3D artist.
One of the most helpful person in the industry I've found to be is Alex Hogrefe. He does awesome work and is willing to share his knowledge and expertise across the board. This kind of unselfish behavior is rare in our field, so I figured I'd pass it on!He has given tutorials on nearly all attributes of rendering techniques. No matter which programs you use (Vray, Photoshop, etc etc) the methods all apply.Good luck in your endeavors of becoming a Visualizer!Also, although 3D programs like Rhino and SketchUp do a great job producing landscape elements, it's hard to beat the 'realism' achieved by harmoniously juxtaposing pictures of real vegetation onto your rendered image (at least when it comes to the everyday constraints of the everyday individual). Unless your Alex Roman (see The Third and the Seventh), it's very hard to find time to realistically model every element, texture and shading for each and every object! That guy is above and well beyond most's league!! If you get competent at a rendering engine and then really good at photoshop you will be fine.
Most of what I see/do is - build the site in SU or whatever and put in billboard plants and people so the scale is correct then export a basic SU image. Overlay that in photoshop with a rendered image of the site at the same size but with no plants or people and add in the plants and people you want using the simple exported image as a guide to get the scale correct. Then use photoshop magic to tie it all together. I'd also toss out that to get good-looking plant material.
Your plant textures require subsurface scattering. You can get away without applying SSS (subsurface scattering) to grass or anything low to the ground.But anything eye level or higher definitely requires it. Plant tissues transmit light through the actual surface of the tissue and it's difficult to get that semi-translucent effect using other cheat methods. Rendering SSS quickly pretty much requires a rack-mount server because the light files for SSS, anisotropy, blurred and translucent materials quickly gets into the gigs.Then there's also the issue of building randomization in real-time via proxy objects and using randomized displacement maps to generate real looking grass while populating a scene with a decent amount of landscape objects.You can minimally do this in SketchUp.
Unfortuantely, SketchUp is only a 32-bit program and will not process files over the 1.8 gig mark. This is where you pretty much get into 3DSmax territory. As much as I love 3DS, I find it a little more cumbersome and difficult to work with than SketchUp. You also get into the argument of objectivity.These images are suppose to reflect real-life scenarios.There's a possible gray area here— just like with a news photo, there's a limit to alterations one can preform on a photo, e.g. Color and lighting corrections. @Stephanie BraconnierI do all the visualisations for my firm and I never. Render grass or trees.
Not just because we don't have the proper software (we use vray + rhino) but also because it takes an assload of time and you can do it just as well if not better in photoshop. If you have the patience to cut out high-quality trees, that is.I think you can use instant function to do grass which are aesthetically more pleasing to audience. If you use instant function, calculation time is not a big part of equation anymore either. I saw a pretty good Youtube video for grass.
3D Renders For LandscapingCreating a 3d rendered image of your landscaping project is a great way to provide clarity for any exterior project, whether you are a homeowner or a landscape architect, RealSpace can help you save time, money and headaches. Pricing for 3d landscaping projects are dependent on the number of features and specificity of the project. We have thousands of pre-made vegetation models at our disposal ensuring you work is created as efficiently and accurately as possible.Landscape architectural visualization, it’s a bit of a mouthful but it is a simple enough concept. We turn landscape plans and ideas into a tangible image which is easy to understand and conceptualize the finished project.
What Sets Our Landscape Architectural Renders ApartBecause of RealSpace’s vast 3d vegetation library and our more robust rendering program, we are able to add almost limitless detail to an image. This means we are not restricted when it comes to integrating trees, shrubs, and flowers into a scene. While most 3d rendering companies are forced to cut corners by photoshopping two-dimensional images into their scenes, which will not react to the environment in a realistic way, we are able to place a large number of trees and have accurate scale, reflections, shadows, lighting, and colour bounces.In addition to accurate renders, RealSpace is able to provide numerous camera angles for a reduced price. The bulk of the work we do is in the initial setup of the scene, beyond this point shifting a camera around and making whatever changes are needed is typically less involved on this end, as a result, we are able to provide less expensive options for 3d rendered packages.
