![]() ![]() If you render using alpha maps this will makes comp'ing the render into the image that much easier. All of that for us is done in PS after the render. The second thing is I personally do not try to comp my render into a background in Vray. The HDR image used for lighting needs to have the "environment" tab checked so it is using the image only as a lighting source and not a background image (hence the difference). Not knowing how much you know or don't know I will start with this: It does not cover everything but gives you a good start. The manual is fairly well written and to the point so I would start there too. It is really a matter of knowing your equipment and taking the time to learn the settings within Vray. What is "fast" on one persons machine may be slow on another. We are rendering to 10 other machines using my MAC as the parent and it has drastically cut our render times (but again this really depends on the scene). Anytime you can split a render up and get the help of other computers power it will make things quicker. It makes a world of difference even if the other computers are not fast machines. My first suggestion is render to every available computer (DRSpawner). Lights and how many lights are in the scene As far as speed goes it is dependent on so many variables: ![]() If you’re looking to fix the Shadow/Sun problem caused by the HDRI, go HERE.These are some really good and well written tutorials for some standard set-ups. If you encounter any issues such as a Black Background or a Transparent Background, please head over to this post HERE for a fix. Hope this tutorial comes in handy for your next project! UPDATE: You can post-process it later in Photoshop to tweak brightness and shadows. If you’re making a daylight scene and want the sunlight to play a bigger role than the other lights, uncheck ‘Exposure’ in the ‘Camera’ tab, and amp up the ‘GI(skylight)’ value.Always choose an image that is actually related to the approximate location of the model, as in, don’t choose a mountain view for a down town bachelor pad.Use images above 4 MP you can find those via Google’s image search, and from ‘ Search Tools‘ choose ‘ Larger Than.‘ then ‘ 4MP‘.It should come out looking like this Boys’ bedroom in the same apartment as the Master Bedroom If you’re rendering a day scene and want the light to show, tweak ‘GI(skylight)’ value till you get what you want. Now render! It should come out looking like this Scroll down to ‘UVW’ and set ‘UVW Type’ to ‘UVWGenEnvironment’ and ‘Mapping Type’ to ‘Spehrical’. Make sure you choose the exact image for both ‘GI(skylight)’ and ‘Reflection/refraction (background)’. Note: The steps we’ll be doing should be applied to both ‘GI(skylight)’ and ‘Reflection/refraction (background)’.įrom the drop down menu under, choose ‘TexBitmap’. Open your VRay ‘Options’ window, and head to the ‘Environment’ tab, Make sure that ‘GI(skylight)’ and ‘Reflection/refraction (background)’ are checked and then press the ‘M’ button in ‘GI (skylight)’. ![]() If you want over 600 MB of FREE HQ HDRIs (Sky + Background) files, then continue to the end of this post. So, unless you want that certain effect, choose your background wisely. Note: Keep in mind that the overall color of the image will influence the color of the natural lighting, for example: if you use an image that has a lot of orange hues, the natural lighting will be tinged orange. I’m using VRay 2.4 and Sketchup 2015 if you have different versions and have questions, feel free to drop a comment.įor the 3.4+ Tutorial, coming Sunday, 11th of August 2019. To get to it you’ll need, either a HDRI or a HD image with a panoramic view (Day, Night, or Dusk) you can choose anything you like or think would help with the final render/location of model. While going around finding something new to learn that could spice up my renders, I found this really easy way to add backgrounds to your models without using a Dome Light (I mentioned that method in a previous tutorial).
