-====== The 3D Preview ====== 
- 
-To access the 3d preview window, click the Show/Hide 3D Preview Window button which is located in the General group within the Main Tab or hit the '​P'​ key. From here you can set up the way in which you preview your results within Knald.

- 
-**Albedo:** This button allows you to import an Albedo texture that can be viewed on the primitives or imported meshes within the 3d preview window. 
- 
-**Metalness:​** This button allows you to import a Metalness texture that can be used to control where conductors (metals) & insulators/​dielectrics (non-metals) are shown on the imported mesh or primitives within the 3d preview window. 
- 
-White (1.0) represents conductors (metals), black (0.0) represents insulators/​dielectrics (non-metals) & gradients between black & white represent transitional areas where the shader will blend between conductors & insulators/​dielectrics. 
- 
-**Smoothness:​** This button allows you to import a Smoothness texture that can be viewed on the primitives or imported meshes within the 3d preview window. 
- 
-Smoothness textures define how smooth the micro-surface is on an object with black (0.0) representing 100% rough & white (1.0) representing 100% smooth. 
-If your workflow requires the use of Roughness textures (perceptual) rather than Smoothness, you may use the "​Invert Smoothness"​ checkbox below as both representations of the micro-surface are the direct inverse of the other. 
- 
-**Mesh:** This button allow you to import an .obj or .fbx mesh into the 3d preview window. 
- 
-**Albedo/​VCols:​** This toggles the display of an imported Albedo texture or baked Vertex Colors on/off. 
- 
-**Albedo Alpha:** This toggles the display of alpha transparency on/off. The alpha channel in the Albedo texture is used to store the transparency mask. 
- 
-**Metalness:​** This toggles the display of an imported Metalness texture on/off. 
- 
-**Smoothness:​** This toggles the display of an imported Smoothness texture on/off. 
- 
-**Parallax:​** This toggles the Parallax effect on/off. 
- 
-**Colored Lights:** This toggles colored lights on/off. 
- 
-**Backface Culling:** Enables or disables backface culling in the 3d viewport. 
- 
-**Self-Occlusion:​** Enables or disables self-occlusion in the 3d viewport. 
- 
-**Filtered Reflections:​** Enables or disables filtering of reflections in the 3d viewport. 
- 
- 
-===== Lighting Settings ===== 
- 
----- 
- 
-**Image Based Lighting** Toggle the use of Image Based Lighting within Knald. 
- 
-**Load Panorama** This button allows you to import a Panorama to be used for Image Based Lighting. 
- 
-**Lighting Presets:** This drop down menu allows you to choose between various lighting configurations,​ with which to better view your results. There are 4 presets to choose from. 
- 
- 
-===== Surface Settings ===== 
- 
----- 
- 
-**Albedo - Dielectric:​** This controls the base color of insulators/​dielectrics (non-metals) on the imported mesh or primitives within the 3d preview window. 
- 
-**Albedo - Conductor:​** This controls the base color of conductors (metals) on the imported mesh or primitives within the 3d preview window. 
- 
-**Smoothness:​** This defines how smooth the micro-surface appears on the imported mesh or primitives within the 3d preview window, with 0 representing 100% rough & 100 representing 100% smooth. 
- 
- 
-**Invert Smoothness** Inverts the Smoothness texture to make Knald compatible with the Roughness texture (perceptual) workflow. 
- 
-**Surface is Metal** A toggle to change the reflectance values displayed on the imported mesh or primitives within the 3d preview window between conductors (metals) & insulators/​dielectrics (non-metals). 
- 
-  * Checked will use the correct values for conductors (metals). 
-  * Unchecked will use the correct values for insulators/​dielectrics (non-metals). 
- 
- 
-===== UV Coords ===== 
- 
----- 
- 
-**U & V Tile:** Here you can change the tiling shown on the objects within the 3d preview window in the U & V directions independently of the main UV Tile functionality. Changing the value will increase or decrease the number of times that the texture is tilled along the surface of the object. 
- 
-**Reset UVs:** This button resets any changes you have made in regards to offsetting or tiling the UVs within the 3d preview window. 
- 
- 
-===== Transmission Settings ===== 
- 
----- 
- 
-**Translucency:​** This toggles translucency on/off. 
- 
-===== Bake Options ===== 
- 
----- 
- 
-**Cage Color** - Here you can change the color of the cage mesh. 
- 
-**Wireframe Color** - Here you can change the color of the cage meshes wireframe. 
- 
- 
-===== Post FX ===== 
- 
----- 
- 
-**Background:​** Here you can change what is displayed in the background of the 3d preview window. 
- 
-  * Color: Sets the 3d preview window background to a solid color. 
-  * Skybox: Sets the 3d preview window background to the Skybox currently being used for Image Based Lighting. 
-  * Ambient: Sets the 3d preview window background to an ambient version (Irradiance) of the Skybox currently being used for Image Based Lighting. 
- 
-**Exposure:​** Here you can change the exposure of the image used for Image Based Lighting. 
- 
-**Reinhard:​** Tonemap the 3D Preview using the Reinhard algorithm. ​ 
- 
-**Surface is Metal** A toggle to change the reflectance values displayed on the imported mesh or primitives within the 3d preview window between conductors (metals) & insulators/​dielectrics (non-metals).

-**View Type:** This dropdown menu controls what is displayed on the primitive or imported mesh within the 3d preview window. 
- 
-There are 11 options to choose from: 
-  * **Lighting** - This shows the fully lit primitive or mesh with any textures that you currently have imported. 
-  * **Height Map** - A preview of the generated Height map. 
-  * **Ambient Occlusion** - A preview of the generated Convexity map. 
-  * **Concavity** - A preview of the generated Convexity map. 
-  * **Convexity** - A preview of the generated Convexity map. 
-  * **Normal** - A preview of the generated Normal map. 
-  * **Derivative** - A preview of the generated Derivative map. 
-  * **Transmission** - A preview of the generated Transmission map. Transmission is only available after it has been generated. 
-  * **Vertex Color** - A preview of the generated Vertex Color map. Vertex Colors are only available within The Baker. 
-  * **Curvature** - A preview of the generated Curvature map. 
-  * **Material ID** - A preview of the generated Material ID map. Material ID is only available within The Baker. 
-  * **Bent Normal** - A preview of the generated Bent Normal map. Bent Normal is only available within The Baker. 
-  * **Position** - A preview of the generated Position map. Position is only available within The Baker. 
-  * **Transfer** - A preview of the generated Texture Transfer map. Texture Transfer is only available within The Baker. 
- 
-**Object Type:** This dropdown menu controls the type of object that you wish to use to preview your results within Knald. There are 4 options to choose from. 
-  * **Cylinder** - A basic Cylinder primitive. 
-  * **Sphere** - A basic Sphere primitive. 
-  * **Plane** - A basic Plane primitive. 
-  * **Cube** - A basic cube promitive. 
-  * **Mesh** - An imported .obj or .fbx mesh of your choosing. 
- 
-  
- 
-**Tessellation Level:** This slider controls the amount of tessellation shown on the objects. Tessellation is based upon the ratio of 1 polygon per pixel at level 7, with the polygon count reducing by 25% as each level on the slider is also reduced. 
- 
-A 2048² texture contains 4194304 pixels and as such the number of polygons use in level 7 during tessellation would be 4194304 when using a plane. If the slider is set to level 6, the new tessellated polygon count on that plane would be 3145728. 
- 
-  
- 
-The following levels of tessellation for each level, based upon a 2048² texture as shown on a plane, is as follows: 
-  * **Level 7** = 4194304 polygons. 
-  * **Level 6** = 3145728 polygons. 
-  * **Level 5** = 2359296 polygons. 
-  * **Level 4** = 1769472 polygons. 
-  * **Level 3** = 1327104 polygons. 
-  * **Level 2** = 995328 polygons. 
-  * **Level 1** = 746496 polygons. 
-  * **Level 0** = 559872 polygons.

-**UV Tiling:** Here you can change the tiling shown on the objects within the 3d preview window. Pressing the +/- buttons that are located on the numpad will increase and decrease the UV tiling on the primitives/​meshes. 
- 
-Holding CTRL or Alt in addition to +/- on the numpad will offset the UVs in the U & V direction respectively.
