The next step is to assign the right materials for our scene (Pict_08). When we render the szene, we can not see the reflection effect that cause the HDRI mapping from the background.This is because our material does not have the characteristics for this. If the direction of the sun does not match with HDRI lighting, then you can edit this in rhino properties with the desired results. So we have to put down the sun intensity in rhino properties (Pict_06), to 0.1, and the size multi to 5 to avoid contrasting shade (Pict_07). We do not use the sun as a second illuminating, but we need it for a better shading in our scene. We do not need to map the sun to the environment parameter. Under Wallpaper panel, add the background (we can keep adjusting the view to fit in the background better). 4 2.1 Download a proper background for the view from Google Image. Since we work with the file-part 01 continues, and know that we have created a sun system there, We have to integrated the sun with our environment parameters illumination now. In V-ray asset editor, objects tab, choose the Rhino Document Sun, and set the size to 10, which makes the shadows a lot softer. When we do this, the f_number, shutter speed and film speed have no more influence to the exposure. So we should disable the checkmark of the exposure and vignetting by camera section in Vray render option. Now we want to illuminate the szene with the HDRI and therefore we do not need to control the exposure with the physical camera as previously (Pict_05). We want to assign the same HDRI bitmap to the background parameter. Now we can use a HDRI bitmap and assign it to the GI parameters (Pict_04). To do this, we must click the letter „m“ near the file in bitmap section. With the GI HDRI we want to illuminate our szene and with the HDRI for the background we want to create an environment pict (sky) for the reflection in our szene. In the uvw section we should click to the environment and for mapping „spherical“ (Pict_03).Īt least you need HDRI skies-bitmaps for the GI and background. And my classmates are all admiring my renders. VRay tutorials make me feel so easy to do the visualization works. We want to replace the sun for the HDRI bitmap. Proper introductions, the background of Rhino, planning a model, step by step progression stages, and awesome exercises to practice each tool for certain architectures modeling tasks. Near the „Type“ parameter click the pop up menue and choose „bitmap“ for your light source (Pict_02). ![]() Open the environment tab in VRay render option tab (Pict_01).Ĭlick the letter „M“ to the right of the GI parameter to open the Vray texture editor. Now we want to map the HDRI to the enviroment parameter: GI and background. Further we want to bind the sun system to get better shadows to our szene.įor this example we want to use our previous szene to obtain a direct comparison with the sun and sky lighting as before. In this part of exterior tutorial we want to use HDRI to get an accurate illumination. How to use HDRI and sun system to get illumination in our szene.
