Creating a scene of the exterior. Lesson from gus_ann. Part 3.In this part of the lesson we will deal with vegetation. We will grow grass, trees, bushes, trees.There are many methods of propagation of grass on the surface, mainly these are various plug-ins.For this purpose I will use the plug-in "Forest Pro". "Forest Pro" is an excellent plug-in that supports Mental Ray, VRay, VRayRT, Maxwell Render, Octane, Arion, Thea Render and Corona Renderer, it allows you to propagate any geometry (bagels, teapots, carpet nap, or fallen autumn leaves, as in The example of Denis "visualization of the autumn park") on the surface (not necessarily even), but if you use the licensed version, you will have to pay about 190 euros. There is also a free licensed version of this plugin -Forest Pack Lite, although it carries a number of limitations, namely: A limited number of distributed objects, Limited areas for distributed objects, Spread over an uneven surface is impossible, You can not convert a created Forest object to an Editable Mesh.On the official site of the plug-in you can see video tutorials on how to use, most of which are based on the use of the Forest Pack Lite version, as well as the ability to download the original lesson scene and practice.For work, we also need the vegetation itself - grass and trees that we will distribute. For quick work, I will not model vegetation myself, but I will use already ready models. I use three Evermotion books:Archmodels vol. 124 (models are made for versions of max 2010 and higher)Archmodels vol. 106 (models are executed for versions of max 2009 and higher)Archmodels vol. 117 (models are executed for versions of max 2009 and higher)GrassIn the top view, I will draw a closed line - the area of grass propagation, like this: For this site I will use clover, you can take any grass - dandelions for example: I will join the model 048 to my scene, prescribe the textures to it and put it away from the main events of the scene, so that I know where the model is located and it did not fall into the camera's visibility.Create a Forest object.I'll draw the drawn line, and go to Itoo Software: Click the Forest Pro button and click again on its line, which can be pre-insulated: The appearance of this menu will change. The Forest Pro - Forest 001 object will be created and the program will ask what we end up creating? Click on the modifier button: We will see that now we have Forest 001 consists of standard default objects, which the program set by default. You will see large, rarely located planes perpendicular to the ground. Next, we need to tell the program that instead of these planes we need a clover: To change the standard geometry, we must click on the plus button, so we add one more element of the grass, distributed inside the closed line:Another line called New Item appears, select Custom object below, click on the None button, and click on the clover model in any projection window. Then a window will appear asking you to "Display the geometry of the grass as a proxy?". Answer - "yes": At the moment it turns out that the object Forest 001 consists of two elements - planes and clover. Select the line with the proposed default geometry and click on the cross - delete it: If we now render, we will see that clover in the scene has appeared, but it is so rarely growing that it is not noticeable at all: Let's correct this situation.Let's go to the Distribution Map (map of the distribution of the object), put the Dense card (dense, thick).The density is 3000 Units: Also I found the clover large, so I globally change the scale of the grass in the forest pro itself, in the scroll Geometry: Here's what happens: I do not like some empty areas where the grass grows unevenly, I change the parameter of the grass fusion: Also, I will reduce the amount of displayed grass in the viewport in the Display: Render: All would be nothing, but that's only my grass is some kind of the same, there is no diversity in it in slope, height, turn. I'll go into the Transform roll, turn on the ticks for transforming the grass on the slope, turn and height, and also change some parameters: Render: If you think that the clover grows too tightly, reduce the merger threshold in the Distribution Map, picking the value to your taste: Render: Well, it looks like the truth.TreesI will use several trees from Evermotion Archmodels Vol. 106: Christmas tree from the collection Evermotion Archmodels Vol. 117: I'll start adding the trees in turn to the stage.
I join the first tree, I isolate it. The tree is assembled into a group - it consists of separate objects, so I, first, ungroup it, then select one object of the tree (if necessary, translate it into Editable Poly) and attach to this element all other parts of the tree to get a single object. I'll assign the texture to this model and translate it into Proxy. Since I do not have many trees in the scene, I will multiply all the trees using the instanse method and manually put the models as I need, while I will rotate and scale them: In the background I will put the birches in the same way: Firs and bushes I need to close the black line below the horizon, where the sky ends. This problem has several solutions: Use another HDRI map, which has below the horizon line there is earth, grass, etc., Instead of the usual plane, use the Vray plane, then this plate will go to infinity, thereby matching the horizon line of the HDRI map, which, as we know, is also infinitely removed, The creation of a certain relief of the earth - that is, the very plane-ground must be bent and raised in some areas so that it covers the black strip. With a curved relief, you will not be able to use the free Forest Pack Lite plug-in, and I want you to do it with minimal expenses.I took the bush Bush continuation.Arrangement of trees and bushes: Render: I would like to add a little grass, in the foreground where the clover grows, on the sides of the bench and behind it.I will use Forest Pro. Hide all trees, trees, to see an area of tall grass - the place where I need to plant it: Draw this area with a closed line:I chose the grass the following way: I will join the model of grass, I will prescribe the texture. I'll select the drawn line, create Forest 002 (in accordance with the way we planted the clover), I will change the standard geometry to my grass. Here are my settings for the propagation of grass: There were little things left - texting the border, composing the composition, it is possible to add some small things - a book, garbage on the road (leaves, sticks, pebbles, bulls), etc .: In the next part of the lesson, let's take a look at the option of setting the camera's depth-of-field and set the final render settings.
