Using V-Ray for SketchUp, when loading a Dome light+ HDRI in default setting, the render result will be darker in nature (See image 2.0/ Setting 2.1.A).
In comparison to Dome light and V-Ray Environment settings, the shadow appeared to be sharper when rendered using V-Ray Sun and sky system. However, when you turn on the GI Skylight option and choose the V-Ray sky as the light source, the render result will be similar to V-Ray default settings. Under Environment Overrides, the GI Skylight is technically turned off in default settings. If you go to V-Ray Asset Editor> Settings> Environment> Background, you can see that the default background is set to V-Ray Sky or technically the V-Ray Sun (V-Ray sunlight). When set in default setting, notice the sunlight is enabled. In V-Ray default setting, V-Ray Sun and V-Ray Sky are special features which are provided by the V-Ray Renderer. For V-Ray Environment with HDRI texture, the test render will highlight the possible output when render in optimized setting using HDRI as the light source and V-Ray sun as an additional light source. For V-Ray dome light with HDRI texture, a comparison test render was made using default setting and optimized setting. I also added a Sphere model inside the scene with silver polished material in order to see the reflection of the sky.įor V-Ray Sun and Sky System, I set up a basic scene in default setting and lit it a couple of different ways, (enabling and disabling) V-Ray sun, background, and GI (Skylight). In order to fully understand the possible render output in V-Ray using various environment settings such as V-Ray Sun and Sky, Domelight+ HDRI and V-Ray Environment + HDRI, I made a simple rendering experimentation that highlights different parameters or settings which generally affect the tonality and atmosphere of the rendered image output.ĭuring the test render experimentation, I enabled the material override and set the water pool to “Can be Overridden”. Thank you for taking the time to read this.Exterior Render Settings (V-Ray 3.4 for SketchUp)Įxterior Render Settings V-Ray and SketchUp Please let me know if this request is out of topic in blender development forum. I take the liberty to open this topic because I did a lot of research and I was very surprised that I could not find any topic discussing this. We sometime want to have a specific HDRI contributing to a specific piece of geo in one passe ( for example, eyes of a character, or windshield of a car ).
We also use multi light AOVs, to be able to adjust those exposure in post> This allow us to have more control other exposure of the ground / sun / sky while using image based lighting only, which is better than a directional light when using PBR shaders.
So its’ hard to create a plugin for blender, if blender ignores the fact that most render engine use dome lights.Ģ- Multiple dome lights for more control :Ī lighting workflow we use sometimes, is to actually have 3 HDRI contributing to the beauty, for example we have one dome light for the sky, one other dome light for the ground, and one for the sun ( keyed out from the sky HDRI ). Most renders use a dome light for the exposure and sampling control of this specific HDRI in the dome lights parameters. To explain why we need Dome Lights in modern lighting workflow, I will give some examples :Įnvironment lighting using an HDRI or a Physical sky should be treated as a light in the UI. Using a world slot to do Image Based Lighting is, IMO, a very old way to approach environment lighting, and this should be addressed in Blender.Īll render engines I know are now using dedicated dome/env lights, the world slot for HDRI died with MentalRay and probably a old version of Vray as far I can remember. My understanding is that, in Blender, if I want to light a scene using an HDRI ( not matter the render engine used ), the only way is to plug the HDRI in the world slot, and I need to use a math node if I want to expose up or down this HDRI in blender. The issue is not about Cycle, but the fact that there is no Dome/Env light objects at all.
VRAY FOR BLENDER DRIVER
I want to use blender as my daily driver 3D application for all my personal work, and I can get around a lot of its uniqueness, and actually like most of the UI decision made since 2.8.īut as a lighter with now 10 years experience, I have a really hard time not having a dedicated dome light in Blender. I am a VFX artist with experience using Pixar’sRenderman / Arnold / Vray / mentalRay ( back in the day ), and testing a lot of render engine for personal interest.
