V-Ray: Depth of Field
-
Thought that I would have a look at the DOF feature on V-ray.
For scale... a person in this model is 340mm tall.
I have used an aperture of 1
and an Override Focal Dist. of 80This scene is made up of 2036 simple domes and 2314 spheres.
The model file size is 349kb in size.I have attached a render of with and without DOF
-
DOF is one of the difficult thing to achieve in the current vray but you made it. how did you know your camera distance.
-
yeah.., how did you know a distance or lenght about your camera active with object that you want to focus

Sorry it taken so long to reply, I lead a busy life.
Initially to get the DOF correct, I made boxes to the scale I was working at in a new scene.
(So, if the model is small, like 500mm big, I'd make the boxes 100mm in size.)
I then stacked them side by side into a line and viewed them with so I could see one and the rest were going further away. I then guessed a distance to try and saw which boxes were focused and then worked it out from there.
I hope you understand

I hope you understandgood idea. in case ofg now using rb. in sketchup we can use the position camera. all we have to do is to draw a line and know that distance then position that camera on that line. therefore we will know exactly the camera distance.

I didn't quite understand what you are meaning. Does that mean that there is a script so that can draw a line, and the script tells you how far away that line is so you can input that distance into the DOF distance in V-ray, and it will be correct?
-
there is actually a number of free ruby scripts that allow you to eather mark camera location or even tell you the distance to a particular object, this takes out all guess work of setting the distance in vray
CameraDistance.rb - Returns the distance to an object in the direct line of sight.
cameraLines.rb - Connects all cameras of all pages with lines. (needs more then one page)There is also old Film & Stage plugin that kind a works in sketchup 7, allows you to mark camera location, and do all the measurement.
