7. corrected linear workflow Gamma correction compensates for a monitor s tendency to display mid tones darker than they actually are Most programs embed the correction for this into the image but because of the nature of how V Ray processes color information it does not correct for this Ultimately the result is that the Vray Sky will appear too dark if it is not corrected for display on our monitors Also if the image is not gamma corrected the influence of the sky will not be accurate either Needless to say gamma correction is very important extremely so when using the V Ray Sun and Sky The image on the far left is has no gamma correction This causes the sky to be dark and its colors to be inaccurate The closer image has been gamma corrected which brightens the sky as well as having colors which accurately represent the sky s influence Enabling Gamma Correction In order to gamma correct images Render both the inputs textures and colors Reflection efraction M Batch render Low thread priority M Show progress window Gamma Correction Output 2 2 Input 22 Correct RGE I Correct LOR Textures Indirect Illumination and output need to be adjusted M Max depth 5 E with V Ray as well as not impeding z F Default Lights Shadows corner containing the controls for Don t render final image Correct LDR Textures To adjust the This is very quick and simple to do Hoy Wasp Lave 5

GROUND Self illuminated material can make the object become a lightsource itself It does not limit to a certain shape like a regular light type does Every part of the object can be illuminated and used as a lightsource Self illuminated material is perfect to create objects like light ball light tube light shade stylish lighting cold light and lit screen However emissive materials should not be used as the primary lighting for ascene If you are using a physical camera in your scene you may notice that your light emitting materials render black or darker than expected This is because the physical camera reacts differently to light than a regular camera does Because of this you may have to make your light emitting materials significantly brighter in order to be rendered by the physical camera V Ray for SketchUp 45 Adjust the Intensity Default set the Intensity to 1 Below images are rendered with Intensity of 3 left and 5 right Adjust the color Default set the color to white Click on the color box to change to a different color Notice that if the setting of the Intensity is too high the color of the object itself will become close to white Only the light come out from this self illuminated object will carry the correct color Sowe recommend you not to use this as anormal lightsource Just make it as a decorative object in the scene Please refer to below image chart for results of vario

The plane on the left has a texture multiplier of 25 and the plane on the left has a multiplier of 1 You will notice that the rendered image is the same in both cases That is because it is does not matter the method that is chose only that the multipliers are inline with the desired effect The image on the left is an example of the different quality settings for displacement The plane on the left has an Edge Length of 24 pixels and a Maximum Subdivision of 6 The plane on the right has an Edge Length of 2 pixels and a Maximum Subdivision of 512 Here is a comparison of bump mapping left and displacement right Both the maps and intensities are the same As you can see the bump map is limited in its ability to create the depth that is capable with displacement Example 1 Example 2 V Ray for SketchUp 55 ransparenc What s Transparency Mapping Transparency mapping is another method using Bitmap to create materials The difference is that this is using alpha channel to get rid of unwanted part of the Bitmap saving only the part covered by alpha channel This is called a mask This is used mostly for creating product logos stickers and numbers Many users try to avoid using transparency mapping and model the actual object in the scene Although you can ignore material settings by creating the actual model of objects that will increase both the number of objects in the scene and the file size
21. This example shows that Environment light in semi open spaces usually doesn t lead to a proper solution the first time When begining to set up the illumination for interior space a first step should be to check how many openings in the scene allow environment light to come in This includes transparent objects like windows or doors It is also important to know how many lights are intended to be in the final scene as well as what time of day the rendering is meant to depict These are all very helpful for setting the Environment light correctly V Ray for SketchUp 67 Even if the Environment lighting is set to the desired level for the final scene you will still wind up having to adjust it based on the materials and other lights that will be added to the scene Very often the camera got moved during this process and the quality and brightness are not what you were expecting Even though the interior lighting is under control once the camera is pulled out from the box you will get the bright white rendered result as the image on the left It will still be necessary to add light in the room adjust the brightness and render as image on the right V Ray for SketchUp 68 Choosing different Render Engines In order to calculate indirect light within V Ray a render engine must be specified to compute those calculations Each engine has its own method of calculation and each with its own advantages and disadvantag

106. to recreate the texture of a surface by using a black and white image to describe the varying height of the surface This is very similar to how bump mapping works but each method does this ina different way Bump mapping simply shifts the surface according to the image applied to it without actually changing the geometric structure of the surface This causes bump mapping to be somewhat limited in its capabilities of representing those surfaces Displacement on the other hand actually creates the geometry that is described by the image This is done by subdividing a given piece of geometry and adjusting the individual heights of all of the faces based on the image that it is describing The result is a surface that produces a much more accurate and realistic result Adding Displacement Using displacement is very similar to using bump mapping In fact you can probably use your current bump maps as displacement maps Inthe Maps rollout of the material options there will be an option for Displacement Enable displacement by clicking the check box on the left and the proceed to click on the m to adda displacement map Although textures are used for displacement maps in most situations it is possible to add a displacement map via the procedural mapping Once either a texture or procedural mapping is added there is one last thing that you will have to pay attention to while still in the texture editor and that is the multiplier The multiplier is

111. w that the Two Sided Material has been feck added we will expand the material and Bak notice that this looks much different then Coor M the standard V Ray material This is because the Two sided material works with predefined materials There are two slots one for the front material and one for the back material as well as color which will determine the ratio between the front and the back material E E Default _VRay_Material Two sided vra You cannot actually create a new material once inside the Two Sided material as it only works with predefined materials When you click on the button for the front material a dialog box will open up asking you to choose which material you would like to have be the front material You must also define a material a material for both sides but you can define the same material for both sides If you don t specify a material for either the front or the back then Vray will assume that there is no material The color is how V Ray determines the ratio of front material to back material The color works with grayscale values and produces the best results between 35 220 Colors on either end of the spectrum will tend to yield results of almost completely one material which defeats the point of using the two sided material If you would like to recognize which faces are the front and which are the back then you can configure backfaces to be a different color when they appear in the viewpor
