select prim group interactively April 20, 2011, 7:34 a.m.

sorry for my bad English, i don't know weather i understanded your question. in viewport you can select the prims you want to transform,add a “delete” node,change “delete” option to “Delete Non-selected” all primGroups you want transform is here, in textpot type:

echo `primgrouplist(“/obj/geo1/delete1”)`

that's the groups

Thanx for replying,

Nop, that's not what i want to do. Here's to simplify the case : you have 3 spheres, each of the sphere has its own group (group 1,group2,group3). Later you want to modify the position of sphere2 (group2). So you attach a transform node to do the job. In the transform node , select the group/sphere then do the transformation (important : when selecting obj try to pick up from viewport , NOT from the group list !!! ). Done and you're happy with it. Suddenly you realize that u need to update the obj on the top level, and the modification will change the number of point. If you do that, absolutely the transformation u did before will gone wild. You will break your object for sure. So updating the obj will be a very bad idea. Otherwise you have to repeat all the transform. To deal with this thing, do not select obj from viewport, but you have to pick up group name from the group list in the ‘transform’ parameter. With this method , no matter you change your object, the transform node is still working fine.

But the problem with this method is : let say you have hundreds pieces of object (like glass breaking) , where each of pieces has its own group. For sure i don't want to pick up manually selecting group from the list , scrolling down hundreds item, trying to pick up which one is the right pieces, there are gonna be something like : pieces101,pieces102….pieces340 etc to select from. In this case , it's absolutely clear that you'll love to pick up INTERACTIVELY from viewport.

Oops,sorry just read your message more carefully, you were already doing that. Yeah, that's very annoying.

yep, i'll be happy if someone can hack it what i'm confused, it's been version 11 and i believe some people already request the feature … ??? am i wrong ??


select prim group interactively April 18, 2011, 12:57 a.m.

Hi, i got a lot of pieces of breaking object and apply an foreach to spread them randomly, each of pieces has its own prim group. I want to edit some major pieces so i attach an ‘transform’ node (i want to do some custom position adjustment) . I apply ‘tranform for each of selected pieces i want to adjust. Probably end up with 20-30 ’transform' node to adjust some major pieces i want to control. I want to keep this ‘transform’ node ‘alive’ which means, if in case i need to go upstream and do a bit of modification where the number of point will be changed, then i don't want to redo all the edit/transform i've done.

Back to the problem, if i modified upstream and number of point is changed, all the ‘transform’ downstream will screwed up coz it's using pattern based selection. So to have this ‘transform’ keep tracking what it's been done, i need to input group name instead of range pattern. But to get the group name, i have to select from drop down list, which one is which? i have to inspect in the viewport to select the proper group.

My question is it possible to input group name without having to select from drop down list (there might be hundreds items) ? Really i mean, i want to select them interactively the group in the viewport, then get the group name displayed in the ‘group’ parameter of the ‘transform’ node. I switch selection mode to ‘primitive groups’ , it help me select group properly in the viewport, but in the ‘transform’ param , i still got range pattern.

Anyone has any good trick to solve this problem?
