My experience with POV-Tree is that often the contacts between branches and
twigs and between twigs and ramifications are broken. When viewed from a
distance this is not always a big issue. However, when a tree is near the
camera, this is far too obvious. I have partly been able to resolve the
issue by increasing the resolution of the meshes, but this is not always the
solution, and the file size increases dramatically as a consequence.
Does anybody know how to avoid such breaks? Have they to do with bend, curve
and or snag settings?
Any info will be highly appreciated.
Thomas
PS see p.b.i. for an image illustrating the problem. Tree file size: 358 MB,
with highest mesh resolution.

I personally have not noticed this yet. Just started playing with pov-tree this
weekend. Perhaps you are downsizing the geometry for the branches too much. I
know I take it down considerably, otherwise the mesh is just too rez-heavy.
The problems I've had is that it's cumbersome to apply a proper material to the
foliage, and have not successfully been able to make a tree with the UV mapped
leaves.
But, really only playing a day with it and with next to no support, I am happy
with the results.

Hm. I am not aware that I have downsized them that much really, but I shall
have a look at that anyway. Thanks for the tip.

I suspect this is a problem with POV-Tree. I have not been able ever to do
this properly either.

It is a very nice and useful application.

Having tested POV-Tree somewhat deeper, I find that the problem most
probably resides with the mesh converting part of the utility. The tree
rendered in TomTree, as a blob object, does not show the breaks. :-(
