Vue F.A.Q (Last Updated: 2024 Nov 29 1:34 pm)
Quote - Raytraced DOF needs a lot, a lot of anti alias to avoid the noise. If you use Infinite, use the hybrid dof instaed, with 3 or 4 passes. It is less accurate, but renders a bit faster, and it's noise free.
Bruno021, I use Vue 6 Infinite. Yes It sure must need a lot. I will try the hybrid, but how much antialias would I need to use if I want to go the ray trace route? and would I just increase the "Advanced Effects Quality" from 59% to ? I was hoping Vue 6 would have improved the DOF quality. Thanks
In these situations, with user settings, one of the most important settings is the Min number of rays.
Raising it will increase the quality of the blur, but it will also hit you with high render time depending on your image.
In practice, for complex scenes, I found it is usually eaier to use postwork to achieve depth of field, with a photoshop plugin or otherwise.

What is the meaning of 'true DOF' anyway as long as you are getting results you have in mind ? In some ways, plugins can give you more control than calculated 3D DOF particularly because it is not bound by a particular calculation model. Vue's DOF is working quite well in most cases. In more complex cases, it is more efficient or cost effective to use plugins. It's just two different tools in your toolbox :) Check out the results for this plugin for instance. You will see what I mean.Attached Link: http://market.renderosity.com/mod/forumpro/showthread.php?thread_id=2244858
I looked in the backroom, under Rendering, and found an old thread where I did some tests to compare rendering times and settings (with Vue 5 Infinite at the time). I would have to run the same scene with Vue 6 to be fair but for now, you can still check it out and see if the findings still apply.agiel - Thanks for the link to the plugin, this looks really good, just downloaded it now. On my latest image I manually added blur inside PSP for the DOF effect because I thought doing it inside Vue would take forever without guaranteed results as I have yet to learn this process in Vue.. It's looks OK, but I really need to experiment with this concept more.
If you don't have a DOF filter, here is how you can use your gradient :
1- Open your image and gradient side by side
2- Edit the gradient to make sure the range goes from black to white (using Adjustment -> Curves works best)
3- Copy your gradient
4- Set your color image to Mask mode
5- Paste your gradient into the color image. That will mask your image according to the gradient
6- Switch back to normal mode. Your mask / gradient will be transformed into a Selection
7- Go to Gaussian Blur and you should be all set

Here is a more detailed version of what I tried to explain.The main difference with a full DOF plugin is that you will end up having some minor deffects along transitions between shades of grey in your gradient.
A way to reduce that is to apply a gaussian blue to the gradient image itself before copy / pasting it into your mask .
As with many things, a lot of practice is necessary to get it right.

And here is an example of results I came up with using this technique.This looks like the mask after you paste your gradient into your image in Mask mode.
From here, you just have to switch back to regular mode and apply the blur filter to the selection.
Quote - I never set the advanced effects quality above 46%, ever.
Last time I used raytraced dof I used min 12, max 48, 75% quality for the AA settings.
Not to take away anything that Agiel has said, as his approach is great too, but read this post again.
ALL DOF I have done uses these type of settings, and though the render will take longer, it gets rid of the crappy edges.
When you render, the depth map is rendered automatically.
Look at the icons just above the frame of your render window. One has a Z written on it - it's your Z map, or depth map.
Click on it, you will see the gradient and you only have to save it the same way as you save regular images.
Hint- Do not save as jpeg as the compression can introduce black spots in your gradient. Always save as jpg.
