Does anyone has de 3d file of casa Provenza, i just downloaded the tutorial and all the dead links files, but i cant find the building in the 3d warehouse link that its attached to the pdf tutorial. Can anyone can send it to me, i just look at this render and i wanted to learn how to make it, its very nice!!! Thanks!!!!
I'm having an issue where if I do a standalone rendering (using the hotkey), my settings for image resolution work fine, whether a preset or a custom resolution. Then with the same exact settings in place, a batch render of starred views will come out cropped slightly tighter, cutting off some of the image all around, but not in a predictable way. It's frustrating because it takes a long time to compose the views only to have to export one at at time in order to preserve those compositions.
Any ideas? Is this aspect ratio of the batch renderer just something that we'll need to wait for a fix on? Sorry if I'm missing something basic.
Otherwise we are all in love with the software and latest updates! Kudos to the team.
I now typically just make Enscape views to "bookmark" the angles, and then use the standalone capture to save the image, in order to save the aspect. As I mentioned, the batch render seems to crop the images slightly. I also tried widening the field of view to compensate for the crop, but it's still cropping...
Batch render tool is a false friend, it's not working like expected at Rhino too - the different lens length of the saved views is ignored, the lens length of the first batch rendered view is used for all views . I don't used it anymore.
rypat, @Clemson, thank you for your patience, would you please be so very kind as to briefly send me a .zip file for example which contains a bunch of correctly rendered batch exports, alongside ones which are falsely cropped? You can upload the .zip (or .rar) here.
Also, just to make sure I understand everything correctly, but you adjust the Enscape window to a size which is corresponding to the output resolution (correct aspect ratio as well), so that the renderings look identical or very similar to the real-time output, correct? You export some renderings manually via hotkey, the aspect ratio is correct, but once you use the batch render function some come out different looking compared to the real-time output?
Hi Demian Gutberlet a typical workflow at Rhino is, the user save views at Rhino and render them later. The lens length is saved to the Rhino views. The global Enscape FoV option is disabled, since Enscape is using the Rhino FoV. That's fine.
Enscape allow me to choose which of the Rhino views should be rendered during batch rendering and start a batch render process. Enscape reads the Rhino views. And now the FoV is ignored. From an users view it's a bug, since the batch functionality is useless.
What is needed? If the user choose which Rhino views should be rendered by the batch process, than Enscape needs to read the FoV too and not only the camera positions. All informations are saved in Rhino, but Enscape reads a part only. It's a communication problem.
And if we want to make it perfect, than Enscape should read the Rhino camera target and use it for the depth of field focus. That's the standard of all Rhino render engines, no engine needs a manual set focus target.
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.
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.
