Vray Render Settings For Sketchup Free Download

[Gaylene Merganthaler]

VRay Settings are organized in two panels - the main one exposes the default options for scene setup. The default options usually work for many kinds of scenes, but if access to more advanced options is needed, the right-hand side panel of the Asset Editor provides those.

Note that the displayed options in the Advanced settings rollouts change in accordance with the settings from the Default panel. The exposed controls vary depending on the combination of selections between CPU/GPU, Interactive/Production and Progressive/Bucket options. Changing the Quality preset from the Render rollout sets a number of options with appropriate values for the selected preset. Generally, the Quality presets work for a wide variety of scenes and you do not need to adjust the settings any further.

The settings in some of the rollouts are organized in Basic and Advanced mode. You can switch the mode from the toggle button () located next to the rollout title or globally from the Configuration rollout.

You can restore, save and load V-Ray settings (in a .vropt file format) from the bottom three buttons in the Settings panel area. The three options are Load Render Settings from File..., Save Render Settings to File... and Revert to Default Render Settings. These options are inactive during rendering.

The Advanced Camera Parameters rollout can be found on the Camera settings page. The Denoiser rollout can be found under the Render Elements page. The Animation rollout toggle remains grayed out unless an animation is set up in SketchUp. For more information, see the Animation rollout page.

Increasing both the quality and size of the render will also increase the render time so make sure to pick settings that are balanced with how fast your machine CPU/GPU is and your level of patience.

Hello, Im sorry to be messaging you here, I have a hand in in two days and my Vray is taking ages to render. Average time is 2 hours.

I followed the instructions on the thread and changed up my settings a little bit, however i cannot change the disk Caching settings.

Two hours is not that long for a high quality render with V-Ray. Can you post some screenshots or upload your model so we can get a better idea of the level of detail and resolution you are working at?

I Followed your settings for v-ray as well, and for some reason my rendering scene is still not processing. It comes entirely brown and blurry when I do a normal render, and takes 24 hours for an interactive render and more, so I stopped it since I cannot spent so much time on a render since I have to submit a 12 soon. Can anyone help me please?

V-RAY is a computer-generated render plug-in for 3D computer graphics software (3Ds Max, Revit, Rhinoceros, SketchUp, & more). This application is used for video game production, industrial design, product design, architecture, and the interior design industry.

How do we prepare your SketchUp model for a V-RAY rendering? It depends on your process of work. For example, if you directly build all of the models in the SketchUp file and apply the materials while modeling, you can use the V-RAY at any time, even at the beginning of the modeling. Using a completed Revit model for better rendering results, you can use V-RAY after building all of the models and then applying materials and lighting through V-RAY. This tutorial will demonstrate how you create a rendering based on the Eames House 3D model from the Revit model. I only added SketchUp Glass on the model. In the previous lecture, I showed how to import the Revit model to the SketchUp model and apply the SketchUp material. Please refer to the previous lecture for the information.

This way is helpful if you know how to add/edit the material properties. Suppose your SketchUp model already has the SketchUp materials that you want to use for your project. In that case, you can update the material in Asset Editor by editing Reflection, Refraction, Bump, Displacement, and more.

This tip is a trick of V-Ray rendering. Adjusting the intensity of the Sun on V-Ray is not enough to illuminate the interior space. V-Ray users add Rectangular lighting sources on windows to make the space brighter and better render results. This may minimize the noise effects on the render results.

Once your SketchUp model, materials, and lights are ready for a final render, you can turn off the [Interactive] render and turn on [Progressive] and click [Render with V-Ray]. It may differ from the Interactive render, so may need some adjustments to get things right. For example, often, you need to adjust the Exposure Value and Aerial Perspective. You will get a JPG, PNG, or TIFF file from this final render for your post-production, known as photoshopping. The final render will take a few minutes to a few hours depending on the size of the image and the complexity of the model (more points), material settings (reflectivity, bump, displacements), and number of lighting sources.

Thanks for this Brian. It works well.

What is the best way to get the dark shadows you see in the renders I had enclosed?

Is the intention on this to be able to apply the materials without putzing around with texture mapping (rather, just assigning the material into the layer/object)?

Is it best to turn on curves in the render display mode or in the universal render settings?

Thanks!

Render settings are obviously a big topic to cover and there are many different rendering situations like interior shots, dusk shots, and daytime shots that require different setups. To keep things manageable, this first post will be an overview of the basic concepts that I use for setting up a daytime rendering scene. Things like material setup, AO passes, dusk and interior shot setup will come later.

This tab controls the overall lighting of the scene. The GI (Skylight) box controls the sun specifically. Again, the default V-Ray settings are tied to the Sketchup sun. Therefore, changing the sun angle in Sketchup changes the sun angle here in V-Ray. If you have a dusk shot, then you can tweak the sun color or use an HDRI image to generate the light. For this daytime rendering, I left everything at the default settings.

Here, you can set up extra channels to be generated along with the rgb color image. In other words, you create images that separate out information such as reflections, lighting, and shadows, which can then be used as separate layers in Photoshop. For example, I often select Reflection, Refraction, ZDepth, and Material ID for almost every rendering I do. The Material ID is especially helpful to make quick selections of materials.

This is where the resolution is set and where I tell V-Ray to save the file. For quick test renderings, I set the resolution to 1200800. For final renderings, I will bump up the resolution to somewhere between 4500 and 5000 px though I often suggest students can get away with 3000 px images to save time.

As I mentioned above, this is meant to be a brief overview of a typical daytime scene setup that I use. Sometime in the future, I will go over more complex stuff like night scenes, interior scenes, AO passes, dome lights, HDRI, etc. I will try to update this post as the software evolves or if there is information that I forgot to include.

Hello Alex,

As far as I know, V-Ray Sketchup does not render 2-point perspective correctly. How do you overlay Sketchup image exports on top of the V-Ray renderings ( assuming the rendered image and exported image are using the same scene)? Because all of your renderings seems like rendered in 2-point perspective or did you adjust the vertical lines in Photoshop after overlay those images?

Hi Jin, Maybe I can help. The Vray physical camera replicates the typical SLR or DSLR cameras which are controlled by 3 elements. Aperture size (the hole which allows light into the camera) Shutter speed (the duration the aperture is open) and ISO (the sensitivity of the film or now the sensor on digital cameras). These 3 elements are used to create the perfect exposure and they all trade off each other. The larger the Fstop value the smaller the aperture size. Typically Fstop of 1.8 would allow loads of light into the camera so you would need a faster shutter speed to correctly expose your shot possibly 1/1000 of a second on a bright day. On a dull day when there is less daylight you may need to open it up for 1/500 sec to get the same exposure. In reality F1.8 would also gives a limited depth of field, so only a small section of the depth of the shot is in focus the foreground and background are often blurred, which can be useful. This is a trade off for lots of light and fast shutter speed to capture action. So when you step down your aperture (check fstop values on line) you are halving the amount of light and increasing the depth of field. So as Alex says, increasing from 8 to 10 is letting in less light for the same shutter speed and therefore darkening the scene. The iso value can increase the sensitivity of the plate or film, so that ISO 200 is twice as sensitive as ISO 100, so requires half the light to correctly expose the shot. Trade off for higher iso is a grainier image. Some cameras these days offer an ISO value of 64,000 which whilst requiring much less light to expose the film, you get a very poor quality image. In Vray for SketchUp depending on the time of day the sun is set for, play around with the shutter speed and or Fstop values to see the effect it has on the images exposure, for an evening shot take Fstop to 22 and leave the shutter speed to 100 and see what happens, this may be too dark so either stop up to F18 or increase shutter speed to 50. Finally regarding shadows in Vray, increasing the sun size in makes for softer shadows providing the Shadow subdivisions are set to a reasonable value. 16 or 24 Smoother shadows = Longer rendering. Its always a trade off.

Hope that helps.
