1. THIS SECTION HOLDS ANSWERS TO THE MOST COMMON PROBLEMS THAT MIGHT BE FOUND WHEN INSTALLING AND USING FRYRENDER SWAP Q I have installed SWAP successfully but the user interface is disabled when I run the ap plication A Make sure you have licensed the application and you have placed the license ini file next to the swap exe file Q I m trying to load a scene into SWAP but I m getting an error message A In order to load a scene in SWAP you need to proceed through the Generation and offline render stages before Possible causes for a load failure are O You are not loading the same fry file used in the Generation stage and thus your file is not tagged with the information that SWAP needs to locate the input layers You can check this by opening the fry file in a regular text editor and check for the exis tence of the swapDef block near the end Not all the layers have been generated or they can not be located at the swap folder under your scene folder Q How do export my scene to be used in SWAP A fryrender SWAP reads normal fryrender fry scenes so you don t need to do anything spe cial other than exporting your scene from your host 3D application using any of the available plugins Q I m not getting the expected results when I modify my materials A Please note that SWAP s real time compositing technique will produce a close approximation to the unbiased render you would get by using fry2.

3. RENDER TECHNOLOGY SHARING A BASE CONCEPT SIMILAR TO FRYRENDER S LAYER BLENDING RENDER ONCE AND GET AS MANY IMAGES AS YOU NEED SWAP ENABLES YOU TO CHANGE MATERIALS IN YOUR SCENE WHILE KEEPING THE ORIGINAL PHOTOREALISTIC QUALITY OF YOUR IMAGE IN REAL TIME SWAP is aimed at those visualizers who need to discuss review or simply produce a high number of variations of a given scene or object and don t have have the time to render all the images A typical case of use can be found in product or architectural visualization where once the geom etry is modelled the artist creates the materials that will determine the final appearance of the elements in the scene It is often very beneficial to be able to discuss variations on those materials with the client or even show how different materi als can affect the mood of the image as part of a decision making process To do so traditionally you would need to render all the possible variations one by one This process is not only tedious and inconvenient but may even be unfeasible due to hardware budget or deadline constraints With fryrender SWAP you only have to process your scene once to get endless material changes for a given object Moreover the results are displayed in real time while you tweak the materials leading to a creativity explosion in your workflow and better more results given the same time effort So How does fryrender SWAP work Putin short SWAP first bu
