WIP: VR in Vray SketchUp

This is a work in progress. My interest in creating a VR can be traced long time ago. way way back when I was using Max Release 1.5. I would like to try one here using Google Sketchup right after  I posted and interesting tutorial using Vray for Rhino. Check it out HERE.

How did I start in SketchUp? 
Here is a screen grab on the scene I used for my IES tutorial. Basically, I placed my camera in the middle of the room. I created a line and place the camera here.

2. All you need to do is to adjust the height of the camera by moving it long the Z axis. Here is my screen grab. The camera is about 1.2 meter above the floor level.








3. Camera type:. In Vray SKetchup the Camera type must be Spherical and the Field of View (FOV) must be 359.9 degrees.



4. Image aspect ratio

Lastly the image aspect ratio in vray must be 2.0 where the width is 2 times the height. In the Vray output size, tick Override Viewport. Image below shows the image output I am using. 




5. Here is the render

  1. Next step is using another software to create the VR output

  10. gidominik.. try to control your exposure. either by making your camera fstop high or low. if its is too bright raised the fnumber. if its underexpose lower the fnumber. or control the sun intensity under the sky parameter. there is no magic visopt, you have to tweak those two on your own.
