Hello,
I have an issue with the distributed placement of a vray proxy. I tried to fetch all useful information on the following screenshot:

The vray proxy is a tree. The pivot is placed at the bottom end of the trunk in its center (see fv and rv), but this is not also the center of the proxy itself if seen as a box. After distributing this proxy over a mesh I added two circle splines for distribution of some needles (large circle) and for excluding distribution of grass (small one). Now I tried to place these two areas as exact as possible where the trunk should touch the ground by checking the result in the RT window (camera view), which looks ok so far. But at render time the tree is placed with an offset which I cannot explain.
My thought is that this is the offset between the actual pivot x/y and the calculated center x/y of the vray proxy box, which means that the Forest Proxy (thin box in this case) marks the center of the vray proxy and not its pivot? Well, that would be a problem for me ...
Then I found the "Center Displacement" function which corrects this issue for billboards but is also available for custom objects. To solve my problem I would need another displacement spinner for the y-axis. But even with that it would be hard work to figure out the two values for each object that I want to use in the scene ...
Any hints are welcome
