Re: [Bf-committers] F-Stop

Hi again, So the defocus node reads the necessary values needed to calculate an fstop from the camera, but then why isn't it physically correct? I am also very confused about the added max blur, which is why I call this node a purely creative node, and not a 1-to-1 fstop node. When I set the

Hi all, just a small one. The defocus node already has a scene option where users can select where to read the camera from. Jeroen. On 05/17/2015 09:47 AM, Jeroen Bakker wrote: Hi all, Well the defocus node has a setting no_zbuf. this option is used to determine if it needs to preprocess

Hi all, Well the defocus node has a setting no_zbuf. this option is used to determine if it needs to preprocess the z input. When no_zbuf is set, the fstop and active camera settings are not used at all. When it is turned off the fstop is read from the node and the active camera distance,

As I see it, the f-stop value in the defocus node has nothing to do with what f-stop is in Cycles (and in reality). This value in the defocus node is a purely creative tool, and as such should stay, but the name should change to focal blur so it is not confused with the concept and mechanism of

Hi, Indeed there is redundancy there. There's just one reason it hasn't been merged: cycles has its own f-stop number. Ideally we would import the camera f-stop from blender during rendering but that would require us to do a version patch -from- cycles camera data to blender to keep old files

2015-05-11 Thread Jeroen Bakker
Hi all, just noticed that there are currently 2 places where you can/need to set the F-Stop. 1. In the camera settings (was first only visible in cycles, but since viewport project it is also visible for blender renderer) 2. In the compositor defocus node. The compositor defocus node does not

I'm not sure how you can drop F-Stop from the defocus node. it's not guaranteed that render scene is used for compositing, meaning different value might be needed. On Tue, May 12, 2015 at 2:27 AM, Antony Riakiotakis kal...@gmail.com wrote: Hi, Indeed there is redundancy there. There's just

Is it not so that you set it in cycles and then live with the results but in the compositor you can change it real time and see the results? I would not want to loose the interactive aspect. On Mon, May 11, 2015 at 11:55 PM, Sergey Sharybin sergey@gmail.com wrote: I'm not sure how you can
