Last year (seems so long ago!), I mentioned I did some 360 spherical V-ray renders for BLOCK 7, an apartment building in New Zealand, in collaboration with a 3D Visualization team, Dee Dee Studio. You can read the full post here.
Honestly, when I was doing the renders, I did not know they will come out the way they did as virtual room tours. It was Sam, the graphic designer from Dee Dee Studio, who stitched and transformed each image into an interactive medium. I’m not sure what program was used though. However, if you are quite curious on how to achieve a 360 Spherical Render in Vray, here’s how I did it:
1. Open V-ray Options and set the following:
First off, change your camera type to SPHERICAL. To be able to render the panoramic entirety of the room, change the Overrider FOV to 360 (Default is 45). By doing so, if you try to connect both ends of the rendered image, you will achieve a seamless interior scene.
When I was first experimenting with this setting using this tutorial: VRAY MANUAL: Vray for SketchUp New Features Guide on Physical Camera, I kept on producing a black image. I used to think rendering a 360 image in V-ray is unachievable. Luckily, I read through some forums here on the internet saying that the solution to the black image problem is actually turning off the camera by simply unticking the On checkbox.
Another problem I encountered is too much brightness in the rendered images. I learned further that the key to solving this is by inputing 0.0 as the value of G.I. Color under the Environment Setting.
Lastly, to achieve a panoramic view, set the image aspect radio to 2:1 (width:length). Simply input 2.0 in the Image Aspect option.
2. After setting all the parameters, click the R Button and render away. Here are some of my 360 Spherical Renders:
You can now have 360 Spherical renders to transform into virtual tours. Enjoy!
