Distance blur in Iray?

Hera

Is it possible to have distance blur in Iray the way you can in 3delight and if so, how do you do it?

ItsTraveler

There sure is!

-Create a new camera if you hav't already
​-Cameras tab, Turn on Depth of Field for that camera. Then you can adjust the settings like you would for 3DL (Focal Length, FStop, etc)
​-I go into the perspective view to fine tune the placement (There are awesome guides on the camera that show the acutal field that is in focus.

I've been looking for guides, where do I find them?

It seems that when I manipulate Depth of Fields nothing happens, saved for my first try, when the whole image got blurry and grained, and that was not what I was after, I only wanted a slight blur in the background to make my main object stand out. But I have not been able to aquire that.

Also, there are some tutorials and tips in Daz, if you select something, in a window... Down on the bottom, unless you hid the tips.

Also, youtube has many videos showing tips and tricks. Just be sure to add "Daz3d" to your search, and hit video...

There is a box that represents your "field of view"... You have to adjust the akward settings to get your desired result. They do not have a simple "center" and "limit" adjustment. You have to use ancient camera knowledge related to focal-length and distance in mm, instead of real world values. (Well, those are real world, and still used, but ancient in the fact that they were created for camera operators and not for digital mediums.)

It is easy to push the focus beyond reality, in the digital world... It will reverse and then shoot past any logical target, because daz does not limit it to stay within logical confines of the path or even stay within rendering range.

Switch to an overhead or perspective view, when adjusting the ranges with the sliders. The white box should cover most of your area. Then go back to make sure you didn't shoot your actual camera view into oblivion in the process.

FYI: With DoF off, Daz is rendering in "infinity mode", which is what a real camera uses for the "long-range view" or "distant view" or "landscape view". Essentially, a linear collection without any focus at all.

I usually add another camera to look at the DoF camera and it also helps if you make the guides on the DoF camera a bright colour.

Select the DoF camera and go to the camera tab in the Display change the colour of the DoF, make sure the DoF is turned on in the Camera section.

Looking through your second camera use the frame thing to get your Dof camera into view and then in the Camera tab in the Camera section you can use the Focal distance and F/Stop to get the Dof you want.

The aim at and frame commands will set the focal distance to the target item, then adjust the fStop parameter (on the camera, not in render settings) to adjust the narowness of the focal area if you don't want to work with the on-screen widgets.
