Anim8or Community

chuft-captain: I sent you a message.

Replied.

I've made a lot of progress. I'm in Italy now but will return to Califonia in a week and should have an update not too long after.

Great to hear Steve. Along with your re-writes, I hope you also found a solution for that frustrum issue we discussed.

PS. Looks like they don't have the letter "r" on Italian keyboads either. (Hope you make it back safely to "Califonia" though!) :LOL:

I can sympathize Steve as this has happened to me in the past.
On the positive side, I find I usually write better and more elegant code on the second attempt!

Fortunately, though, there is a workaround: Object/Point Edit's "Drag Select" option can be used to select all of the surfaces in the current Object, including those that Ctrl-A doesn't select.

That's interesting because in the scenario I describe above, the drag-select does not select the group in question.
No hurry for me to get a fix though Steve, because I'm not really doing any actual modeling lately ... just using some models I was playing with last year, to test your new code.

Also, to Selden, have you considered importing the STL's directly into Anim8or to see if there's any difference in how they're handled when not converted into OBJ format first?

It looks like I broke this in my latest changes to groups. I'll fix it.

Thanks Steve,

... although FYI I think this has been happening for a while, maybe as far back as build 1269 or earlier, so you might have to look back a ways to find the fault.

Selden,

I've seen something similar. I haven't yet worked out exactly what's going on, so take my comments with a grain of salt.
I think this is related to the Group/Layer changes. It looks like there may be still some gremlins to work out.

In my case I had one group of meshes in layer 6, and another group in layer 0. The (faces of) the groups/meshes in layer 6 were selectable, but (faces of) the group in layer 0 were not.
I disabled the visibility of layer 6, and ungrouped the group which was unselectable. It disappeared, so I re-enabled layer 6, and there were it's constituent parts (whose faces are now selectable). However, if I re-group those objects, they automatically return to layer 0 (at least their group does) and once again, the faces are not selectable.

So there seems to be a few issues here.
1. The sub-meshes seem to retain a "memory" of their previous layer membership when grouped, and on un-grouping, they return to that layer (in this case layer 6). If I then immediately re-group those objects, the new group returns to layer 0. The combination of these 2 things it seems to me makes it impossible to permanently change the layer membership of a group of meshes, because they retain their memory of another layer instead of inheriting the layer of the group.
IMO, if you move a group to a different layer then the sub-groups and sub-meshes of that group should also inherit that change, whether they remain grouped or are subsequently un-grouped.
2. It seems to me that the fact that the faces are not selectable has something to do with the fact that they are in a group. Is this also the case with you?
When I ungrouped, the faces of the ungrouped objects became selectable (in layer 6), but these were also grouped objects themselves, which again suggests to me that this has something to do with the object layer not matching the contained object's layer(s), rather than simply the fact that they are part of a group.

None of this I'm sure of ... more testing is required ... but I hope this helps.

EDIT: Bingo! I've just worked it out.
As I said. the objects contained in my "unselectable" group seem to think they are members of layer 6, even though they are grouped in layer 0. When layer 0 (the group's layer) is visible the group is visible, and the faces are also selectable, BUT ONLY IF LAYER 6 IS ALSO ENABLED. If layer 6 is disabled, the objects remain visible (because they are members of a group in layer 0 (which is still enabled), however they are not selectable because they "think" they're still members of layer 6 (which is now disabled).
It seems that the "selectability" of objects and their faces is linked to their layer membership (and it's visibility status) ... (probably as it should be), but, because they seem to be retaining their memory of layer 6 membership, they are not selectable when that layer is disabled.... even though they are grouped (and visible) in layer 0.

EDIT2:
The selection issue, only seems to be an issue for "sub-groups", "meshes" however still seem to be selectable when part of a group in another layer, even when their own layer is disabled. It seems to me that layer membership is not being propagated down and applied from the top-level group to the sub-groups.

Steve,

I just did a very quick check of the Group/Layer changes, and on first glance it looks great!
Individual and combinations of layers can now be displayed or hidden at will, regardless of the status of Layer 0, and it appears that Layer 0 is no longer treated as a special case. (This I agree with completely.)

I'm sorry, I don't have time to test these changes in depth at the moment, but on a very cursory first glance it looks really good, and I'm amazed you got this done in such a short time since Christmas! Thanks a lot!
I'll do some more in-depth testing of the interaction between Group/Ungroup actions and layer memberships when I have more time, but it's looking good so far.
