Creating an A-Frame House Facade for V-Ray 3 in Rhino: A Step-by-Screen Guide 'doing aback face color for vray 3 rhino'

Introduction

----------

In this tutorial, we will cover how to create a detailed and realistic facade of an A-frame house using Autodesk's Rhinoceros (Rhino) software. This process assumes you have basic proficiency with Rhino and V-Ray 3 rendering engine.

Step 1: Set Up Your Project Environment

Firstly, open Rhino and create a new project. Make sure that mm units are selected from the bottom right corner of your screen as we will be working in millimeters for better accuracy later when exporting our final model into other programs like Maya or Cinema4D!

'Edit Roofs'

----------

Since BuildEdge PLAN recognizes walls and roofs as they are input, you can modify the house as a whole, and move walls or change properties of a roof on the fly. This allows you to quickly change the look of the entire house or any individual properties.

Step 2: Create A-Frame House Geometry

To begin creating our A-frame house geometry:

1. From the 'Architecture' tab in Rhino's top toolbar, select 'A-frames'.

2. Click and drag your mouse left-to-right across a grid to create an A-shape.

3. You should now have two extruded surfaces representing the sloping sides of our roof.

Step 3: Modify Roof Geometry

To modify the shape or dimensions of these initial roof elements:

1. Select both faces by holding Ctrl (Windows) and clicking on each face once you've isolated them in viewports only; then press Enter key.

2. In Rhino's 'Properties' panel located at right-hand side under 'Edit tab', scroll down until seeing 'Sweep 3D' section near bottom left corner where we'll adjust Sweep Parameters.

Step 4: Add Facade Details

With the basic shape of our A-frame house established, let's add some additional details to give it a more realistic appearance:

1. From Rhino's top toolbar, select 'Curves' > 'Spline'.

2. Click and drag your mouse along an edge or face where you want to place detail elements like windowsills etc.

3. Repeat this process for all necessary features until satisfied with overall look.

Step 5: Export as OBJ

Once happy with the details added, we need to export our completed A-frame house model out of Rhino so it can be imported into other software programs:

1. Go to 'File' > 'Save As'.

2. In the Save dialog box that appears:

- Select '.obj' from the file format dropdown list.

- Browse and choose a location on your computer where you'd like to save this OBJ model.

Step 6: Import into V-Ray

With our completed A-frame house geometry now saved as an OBJ file, let's import it back into Rhino for final rendering using V-Ray:

1. Open up a new project in Rhino.

2. Go to 'File' > 'Import'.

3. In the Import dialog box that appears:

- Select '.obj' from the file format dropdown list.

Step 7: Render with V-Ray

Now that our A-frame house is imported into Rhino and ready for rendering using V-Ray, let's set up some basic lighting and materials:

1. From Rhino's top toolbar, select 'Lighting' > 'Photometric Light'.

2. Click anywhere in your viewports to place a light source.

3. In the Photometric Properties panel that appears:

- Under 'Lumen Output', enter a value between 1000-50000 depending on desired brightness.

4. To add materials, go to Rhino's top toolbar and select 'Materials' > 'New Material'.

5. Name your new material (e.g., 'Wooden Planks').

6. In the Materials Properties panel that appears:

- Under 'Diffuse', choose a color for the wooden planking.

Step 8: Final Render

Finally, let's render our completed A-frame house scene with V-Ray:

1. From Rhino's top toolbar, select 'Render' > 'Vray RTAc (Production Quality)'.

2. In the V-Ray Rendering Options dialog box that appears:

- Under 'Resolution', enter a resolution value in pixels (e.g., 2048x1024).

3. Click Render to render your scene.

-------

And there you have it! With these steps, you should now be able to create an A-frame house facade for V-Ray 3 using Rhino. This process assumes some basic knowledge of both software packages but covers all the necessary concepts and techniques required to achieve a realistic-looking final result.
