Hi guys!

We're trying to achieve Depth of Field with Sketch and Toon Spline renderings.

When I activate DOF Map Rear Blur, and Depth of Field in post effects, DoF works, but there is completely now control of it. I can change the values from 0-100 to 10000-10000000 and it stays the same.

When we try and do it in post, the multipass z-depth rendering breaks everytime the splines interesect. When spline 1 is in front of spline 2, then spline 2 is magically in front in z-depth pass.

Unfortunatelly, our looks needs to be rendered in Sketch & Toon and we cannot turn splines to sweep nurbs :/

Any ideas will be very welcome :)

Cheers,
Papoka

Both Sketch and DOF are post effects so unfortunately I think they conflict if you try to render them at the same time. What I would do is render a separate depth or position pass and add DOF in post.

in 16 S&T and DOF (built-in) work fine together (I was surprised)

Hi guys!

They work fine in most cases, but not with rendering splines. Gotta have nurbs/mesh.

We changed the workflow on this one and we ditched sketch & toon completely to achieve DoF in Physical renderer.

Thanks for your input :)

interesting, a spline always blurs max regardless of distance unless it's in front of geometry then it blurs correctly... useful info for later.

I still can't get it to work. Even with geometry behind the spline, it always blurs out the same, regardless of DOF Map Rear and Front settings.

Changing focus distance works somewhat, but I can't understand in what way :/ It does change the amount of blur and the sharp zone when I change focus distance but only with a strange relation to the distance from geometry that's behind it.

Weird science.

I don't think it will work - I just had done a test with a circle spline around a box then cloned that out. Any spline part in front of a box is blurring correctly but the boxes and splines are pretty close to each other.
It's obvious the DOF is based on the geometry Depth Map and even though S&T can produce a depth map which includes splines correctly it's not being used

Yup, I did almost the same test but results are ridiculous :) Your previous post just brought my hopes up.

Thanks for checking it out :)

any solution to this? doing my head in...
also if you have a transparent object with only outlines showing up, the lines behind do not show up from the same object..
