Create a coin 3D model render


Disconnect file from color
Select arrow and hit delete button:

Now if you render it with mental ray, it's will be something like this:

So what we need to do is create approximation for displacement
Open Approximation editor:

Click create button:

Select coin and click assign button:

Now click edit button and adjust it:

Also open file node with our texture and decrease alpha gain:

Try to render, you can see there it's very low details:

So we need to add details to geometry, I made it's simply by extruding faces, and scale them down
Also you will need to create new UV (just repeat steps as shown above):

Tutorial Create a coin 3D model render 10

Now try to render
I also set alpha gain a little lower value, 0.03

So finally tweak blinn as metal and make final render:

Selection & Duplication In Maya

Selection Modes Let's continue by discussing the different selection options in Maya. Place a cube in your scene and click on it—the cube's edges will turn green, indicating that the object has been selected. This type of selection is called Object Mode . Maya has a number of additional selection types, and each one is used for a different set of operations. To access Maya's other selection modes, hover your mouse pointer over the cube and then click and hold the right mouse button (RMB) . A menu set will appear, revealing the Maya's component selection modes— Face , Edge , and Vertex being the most important. In the fly menu, move your mouse to the Face option and release the RMB to enter face selection mode. You can select any face by clicking its center point and can then use the manipulator tools we learned in the previous lesson to modify the shape of the model. Select a face and practice moving, scaling, or rotating it like we've done in the e...

Modelling Tools In Maya

By now you should know how to create a polygon primitive and begin modifying its shape by pushing and pulling edges, faces, and vertices . That's a step in the right direction, but it's really only part of the battle—it's virtually impossible to create a highly complex model from a basic primitive without making wholesale alterations to the mesh. To truly begin making finished 3D pieces , we need to learn how to modify the topology of our model by adding faces and edges where we need more detail or control. There are literally dozens of different tools in Maya's modeling shelf, but many of them are only useful in specific situations. In practice, you'll probably spend 90% of your time using the same five or six commands. Instead of introducing every single tool Maya has to offer and having you forget how to use half of them, in the next few lessons we'll take a look some of the most commonly used techniques in Maya's polygon workflow. Insert E...

box modelling in maya

CREATING POLYGON PRIMITIVES For game environment modeling you will be working with polygons. You will start with basic geometric shapes to model from such as a cube, cylinder, plane and sphere. Two ways to create Polygonal Primitive objects are through Polygon Shelf and through Create menu. Create > Polygon Primitives: Choose Object: Polygon Shelf: Creating Polygon Primitives using any of the two methods above will place an object in the center of the scene. This center of the scene is known as 0, 0, 0 XYZ location or world origin: Going back to Create > Polygon Primitives, you will notice a small box next to each object: This is tool settings menu. Many functions in Maya LT/Maya contain this option. In the case of Polygon Primitives, you use an option menu to define few parameters prior to creating that object. So instead of creating a cube first then resizing it, you can enter specific values and create it: Every time you create the same Polygon Pri...
