The sun becomes brighter and the shadows become darker and stronger.
Since it’s an inverse parameter, lowering the value below 1.0 actually increases the gamma/contrast of the image. Inverse gamma – is one of the most important parameter of the VRayHDRI shader, which should be used to increase the strength of shadows present in the scene. It always needs to have some tweaking and in most cases, additional lights! So don’t be surprised to discover that the same setting will not work for every HDRI. HDRI Maps can come from different artists or sources, some make them stronger, some less. This is just the basics, we dive into much deeper lighting rigs for interior spaces in our VRay Portfolio Workshop I’ve applied some Auto Curves, Levels and Contrast adjustments as basic color correction. Play around with Color Balance and Hue/Saturation to make the image more appealing and correct the white balance. Set its color to the dominant color of the HDRI light.Īnd for post processing, I’ve brought them into Photoshop. Give it a strong multiplier of about 300. Place a new rectangular VrayLight outside the main windows. There is a trick you can use to further illuminate the scene while also boosting the ambiance. Sometimes you don’t get enough light to enter our interior space. get multiplied by each other to get the final intensity which will be used while rendering. Just know that the Overall and Render mult. You can experiment with the Overall and Render multiplier for HDRI Map to get the right light intensity. Set it to exponential color mapping and a noise threshold of 0.008. Use a ‘very low’ Irradiance Map preset with a Light Cache of 800 for testing. To increase the strength of the sun, change the inverse gamma to 0.7. The light from our HDRI now gives us soft bounced lighting and shadows for a pleasing ambiance. Since we won’t be able to see the outside sky in our scene, we’ll toggle the invisibility for our VRay light. For this tutorial I’ve Peter Guthrie’s excellent sky HDRI maps. In this case we won’t actually need to add a VRaySun alongside our HDRI. To light our interior scene, we’re just going to use a VRayDome light with multiplier of 1. Here are the most IMPORTANT CONTROLLERS to an easy way for setting up and test HDRI Maps: VRay Interior HDRI Lighting to add a unique ambiance to your interior scenes.
