To achieve realistic lighting effects in VR scenes, the setting of sunlight parameters is particularly crucial. Real sunlight can improve the texture of the renderings, on the setting skills of VR sunlight parameters, including light source type selection, light intensity adjustment, shadow effect optimization and other aspects, I like to take a look at the VR sunlight realism setting parameters.
Efficient setting of parameters for VR sunlight
1. Drag and draw sunlight (top view) to raise the sunlight appropriately in perspective.
(Or a dialog box appears whether to add vray sky, you can add it if necessary)
2. If you add a vray sky, open the Environment panel (8), drag the added vray sky to the Material Editor, and select "Instance".
3. In the Material Editor, check "Specify Sun Node", and click the button below to pick up the sun you just added in the view.
4. The following parameters should be modified appropriately. (The sky parameter is mainly controlled here, and the sunlight parameter is controlled in the modification panel, and the shape of the sky is directly related to the height of the sun).
5. Modify panel parameters (sunlight):
Intensity multiplication: The indoor test generally starts from 0.1 to determine the brightness of sunlight.
Size multiplication: It has an effect on shadows, generally set to 5-8 in the morning and dusk in the morning, and about 3 at noon.
Shadow subdivision: 3-10, the larger the shadow, the finer the shadow.
Photon emission radius: generally cover the window, or it can be smaller.
Filter Color: Sunlight filters color again, leaving it white or even warm.
The CPU rendering used in VR rendering, this traditional rendering method, can capture the changes and details of the light more realistically, so the VR renderer is very popular in the visual design industry such as architecture and interior, but it is slow in rendering efficiency Using the huge number of server clusters in the cloud, the rendering task is distributed to multiple high-configuration servers, which greatly compresses the rendering time and allows you to get a qualitative leap in the efficiency of drawing production.
As an industry-leading cloud rendering service provider, Renderbus is highly respected for its efficiency and stability in the visual design industry such as architecture and interior. This allows designers and artists to focus more on creativity and design, leaving the time-consuming and technical work of rendering to a professional cloud rendering platform. This not only improves work efficiency, but also makes the final rendering more professional and excellent.
