Use ViSoft Photo Tuning to render photo realistic pictures. Photo Tuning needs to be activated separately.
Set a suitable viewpoint and click Photo Tuning button in View – Advanced menu or press F10.
The preview window is on the left side. The aspect ratio of the preview is equivalent to chosen picture resolution.
Below it is the Exposure Correction slider. By using it you can make picture brigther or darker manually.
Under the slider is preview rendering status. It shows elapsed time and description of current actions or condition.
By right clicking into the preview picture you can select three different ways for preview creation: RT CPU, CPU Production and RT Cuda. RT CPU and RT Cuda are on-going progressive processes which never stop while the Photo Tuning menu is on screen. First result is shown quickly. As time goes on more and more noise is removed. You may change the viewpoint or light settings at any time. The changes are detected and creating of a new preview begins. When using CPU Production you need to click Refresh button after any change. CPU production will create a preview picture and stop rendering.
Quality
To the right of the preview window you’ll find the quality options. ViSoft provides four predefined quality modes.
| Fast | The setting fast doesn’t calculate soft shadows or natural lighting and leaves all quality settings on low level. This mode is useful to get a fast overview on the brightness of all lights in the current scene. Use this mode always in the beginning to check the range of your viewpoint in conjunction to the radius of lights. Pictures made with option fast have only draft quality. |
| Good | This level uses soft shadows with low quality and some other settings that increase quality. Use it to perform enhancements on details and to create pictures with low quality. |
| Perfect | This adjustment computes softer shadows with higher quality and increases other quality settings. |
| Photorealistic | This option calculates quality soft shadows. All other necessary quality settings have high values. You should use this mode when light and material settings have been already finished. The result of the automatically optimized settings is a photo realistic picture with soft lighting and gentle shadows. The calculation time depends on the desired resolution and the power of your hardware. |
Output
Select picture size, define file name, type and folder. Bigger resolution means longer rendering time.
Options
| Enable Auto- Exposure | Auto Exposure is an additional pass before the preview rendering starts. It detects overall intensity and applies modification to settings. By using it you avoid too bright or too dark pictures. |
| Glare Effect | Creates light beams around objects with high intensity. |
| Enable Chamfer Effect | Use chamfer effect to make edges smoother. For example, the edges of sanitary ware objects will be smoother, less sharp. This adds realistic look and reflections. |
| GI Saturation | GI Saturation enables color bleeding. For example, when a light hits a red object in the scene some of the red color will be dispersed and reflected in the vicinity of the object. Value 1 is phisically correct value of this effect. You can lower the value to make this effect less apparent. Higher values will increase the effect. |
| Spherical panorama | When this is enabled the output will create a spherical panorama instead of a picture. |
| Use V-Ray frame buffer for rendering | V-Ray frame buffer is a display window for V-Ray renderings that includes a number of specific features, like performing color corrections and applying lens effects on rendered image. |
Control
| Refresh | Recalculates the preview picture. |
| Enqueue | Inserts a task to rendering queue. You may enqueue several different tasks and then start rendering for all of them from the rendering queue. |
| Show rendering queue | Opens the list of recently created rendering tasks. |
| Create | Starts rendering of one or more pictures. |
