VirtualKitten Posted July 2, 2019 Share Posted July 2, 2019 (edited) I have created three objects (that I upload at one in SL), and set the origin in Blender 2.79 . I have created a single node a denoted in several threads to increase the bounding box of my object in a hopeful attempt to move the origin in SL . this is how it looks in blender Now this used to work if you import to SL but it seems something has changed . Is there now a constraint to do this or am i missing something as it imports with the actual item centre not the bounding box centre?

Fritigern Gothly Posted July 2, 2019 Share Posted July 2, 2019 Although I can;t help you with this issue, I have to say something. You say that you are using Blender 1.5, yet your screenshot shows that you are using 2.79. Is the 1.5 for some other piece of software that you are using?

VirtualKitten Posted July 2, 2019 Author Share Posted July 2, 2019 Ok I have managed to take a picture of my node and am not getting any answers as to what i need to solve this import Link to comment Share on other sites More sharing options...

If so, you have to osrt the elements and make the loose vertice no. 1 on the list before you export. If you don't, the uploader will delete it. Put the 3D cursor at the same location as the loose vertice and in the Mesh menu (near the bottom right of the window: Sort elements by Cursor distance.

VirtualKitten Posted July 2, 2019 Author Share Posted July 2, 2019 Hi chin thanks for your reply You can see the main item is selected so is the node (single vertice) My export setting do not have a 'export only selected' either so everything is exported. Is it just because its one single vertices and has to be a empty mesh? Link to comment Share on other sites More sharing options...

I have now tried with an empty square mesh joined in place of the node this didn't change the centre point in SL either . If i edit the mesh the box is missing from the import. I really don't know why as its joined to the mesh . It should be there ? Link to comment Share on other sites More sharing options...
VirtualKitten Posted July 2, 2019 Author Share Posted July 2, 2019 When i try and join these two items it says there is no mesh to join, uh . There must be something i am missing? Link to comment Share on other sites More sharing options...

The general rule for making render efficient mesh is to work in Edit mode as much as possible, switch to Object or Sculpt mode only when absolutely necessary and when you do, always be prepared to clean up the mesh in Edit mode afterwards.

VirtualKitten Posted July 2, 2019 Author Share Posted July 2, 2019 OMG this is stupid . I created an object cube in my mesh and now its an object and wont convert to a mesh with Alt +C what is happening feels like i am loosing the will Link to comment Share on other sites More sharing options...
Bitsy Buccaneer Posted July 2, 2019 Share Posted July 2, 2019 Delete your cube. Toggle into Edit Mode. Create your new cube. It will now be part of your original object. ------ Create in Object Mode -> separate objects; Create in Edit Mode -> part of existing object. 1 1 Link to comment Share on other sites More sharing options...
Aquila Kytori Posted July 2, 2019 Share Posted July 2, 2019 (edited) Repeating what Bitsy and Rey have already said. 1: In Blender start a new file. 2: In Object mode Add your first mesh Primitive (cube, for example). 3: Tab into Edit mode and do all your editing of this primitive. If you need to Add a new primitive then do this in Edit mode. Adding new primitives or duplicating existing mesh etc in Edit mode will result in in you having a single mesh Object when you tab back out to Object mode. You will have one mesh object to export and import into SL. Adding new Mesh Primitives in Object mode will result in a new mesh Object each time. If you have two or more mesh objects and want to join them into a single mesh object then : In Object mode, select the first object, hold down the Shift key (Shift Select) and one by one select the other objects. With all the objects selected use the keyboard shortcuts Ctrl + J to join them into one object. Now when you Tab into Edit mode you will find that what was previously several objects is now a single editable mesh . Generally you want to do all your Editing, extruding, rotating, scaling and moving about in Edit mode. If you do Scale or Rotate your mesh in Object mode then you should Apply the new Scale and Rotation in object mode before Exporting. (Same applies when using modifiers on your mesh. Apply Scale and or Rotaion before using Modifiers) Ok, now about using a single vertex to increase the size of the bounding box so that the origin (pivot point) appears to be offset when your mesh is rezzed in SL. Normally single vertices (loose vertices) are automatically deleted when exporting to Collada format. There is an exception to this. If a vertex is made to be the first in the list of vertices then it will not be deleted. To make a single vertex first in the list you need to do the following: 1: In Edit mode and with only this vertex selected open the Mesh menu > Sort Elements > Selected. The Selected Vertex will now be first in the list. Edit mode: Single mesh object: Offset pivot when rezzed: Note that if you need a Physics model then the physics model (collision model) should also have an extra vertex (edited to be first in the list) and this physics model will need to be Analyzed in the SL mesh importer. Recap. Generally do ALL your meshing in Edit mode . ☺️ Edited July 2, 2019 by Aquila Kytori 1 2 Link to comment Share on other sites More sharing options...
Aquila Kytori Posted July 3, 2019 Share Posted July 3, 2019 (edited) I was rummaging around in Blender 2.80 beta and noticed that we can see the vertex and or face (or material) order if you enable Developer Extras in Preferences. Edit > Preferences > Interface > Display > Developer Extras. Then enable Indices in the Overlay drop-down in edit mode of the 3D view-port. We now have visual confirmation, if needed; that the extra vertex, (using the method mentioned in the previous post) is the first in the list. the images are big because otherwise it would be difficult to see the numbers. Sort faces by material order: red is first in the list of materials and now sorted again but this time with green first in the material list: Edited July 3, 2019 by Aquila Kytori Link to comment Share on other sites More sharing options...
