Na also!

Ich hatte schon befürchtet wir hätten hier einen "Lizzy".

Viel Spaß mit dem Brigde-Tool.

Hallo und guten Abend!

Mit der o. a. Funktion sollte man Objekte für "Second Life" erstellen können.

"Second Life" ist oder war quasi eine Art Lebenssimulation ala "Sims".

Wie so etwas vonstatten geht ist hier beschrieben.

Hexagon 2.5 - Second Life Sculpties

Hexagon provides sculpty primitives for modeling objects that can be exported in TGA format then imported into Second Life (SL) and applied to a sculpted primitive in SL.

See the following topics for information on creating, exporting, and using sculpties in Hexagon:

Using the Sculpty Primitives

The following steps are used to create, modify, and export scultpies in Hexagon, as well as importing and applying the maps into Second Life.

• Create an SL Primitive and click on

Validate.
[*]Modify the sculpty as needed using the tools listed as safe to use in "Hexagon Tool Use on Sculpties."
[*]Save the scene file as a .HXN file.
[*]Texture the sculpty.
[*]Export the sculpty map.
[*]Texture the sculpty (hints only).
[*]Import the sculpty map into Second Life.
[*]Apply the sculpty map to a sculpted prim in Second Life.
　

Creating Second Life Primitives

To create a Second Life primitive (sculpty):

[*]In Hexagon, click on the
Second Life tab next to the 3D Primitives tab. This will bring up the Second Life primitives panel: OR
1 Hexagon Second Life Sculpties
Choose Tools > Second Life > <primitive> from the menu.
2. Click on the primitive tool icon you want to use.

3. Create the primitive in the viewport just like you would a regular 3D primitive.

　

Importing Sculpty Maps

If you have previously exported out a sculpty TGA file or have one from some other source, they can be imported into Hexagon and worked on. One caveat is that some older sculpty files (like those available on the Second Life web site), may come in too "crumpled" to work with.

To import a TGA file into Hexagon:

• Choose

File > Import from the menu.
2 Hexagon Second Life Sculpties

• Change the file type to Second Life Sculptie (*.tga).

• Locate and select the TGA file and click on Open. The object will be imported into Hexagon.
  　
  

  Hexagon Tool Use on Sculpties

  By default, the SL Sculpties in Hexagon are already mapped and you should not need to remap the primitives. It is not recommended that you remap the sculpties but if you absolutely insist on doing so, remap the sculpties following the guidelines in "Remapping SL Primitives" but do so before you make any modifications to the primitive.

  Tools that can be safely used

  The following Hexagon tools can safely be used to modify sculpties:

  
  

• All manipulators: Translate, Rotate, Scale, and Universal
  

• All selection tools: Object, Faces, Edges, Points, and Auto Select
  3 Hexagon Second Life Sculpties

  • Displacement

  • Inflate

  • Orient - Does not break SL primitive by itself, but unknown what other tools used with this might break it

  • Pinch

  • Quad Tessalation - Lessens edge smoothing on map and may provide better results in SL

  • Stretch

  • Soften

  • Brush

  • Export Bump

  • Increase Smoothing

  • Paint

  • Smooth

  • Taper - All types> Taper Deformer, Bender Deformer, Twister Deformer, and Deformer but may flip the requiring that the TGA file be flipped horizontally in a paint program. Do not re-UV map after using any tool.

    Projection tools that can be used

    The following mapping projections can be used on the sculpties prior to modifying them.

    
    

  • Spherical - Cube (on Y-axis), Sphere, Cylinder, Cone

  • Cylindrical - Torus
    　
    [b]

    Tools that can be used with caution

    The following tools may break the sculpty when using, but judicious use may fix problems with the mapping. Save a backup of the file before using. Results will vary and are up to the user’s skill.

• UV Stretch

Tools that cannot be used on sculpties

The following Hexagon tool(s) should not be used to modify sculpties as using them will "break" the sculpty.

Bend - Breaks the SL primitive and even if UV Mapped before using, will still not perform as expected. Interesting results can be made but it is not generally recommended.

Remapping SL Primitives

The Second Life Primitives are mapped correctly by default so should not require any remapping. But if you must remap (and be very sure of this before doing so), use the mapping methods detailed below. Do not remap after you have used any tools that moved points, edges, or vertices.

To remap sculpties in Hexagon:

1. Click on the [b] & Paint tab.
2. Click on the appropriate mapping projection depending on the primitive type:

• [b]Cube: Spherical Projection on Y-axis

Click on the

[b]Spherical Projection tool

. The cube will look like the image below.
5 Hexagon Second Life Sculpties

• 
  
• In the Properties panel, click on the Init Gizmo on Y axis tool. The cube will look like the image below.
  
• Click on the Validate button.
  
• • Sphere, Cylinder, & Cone: Spherical Projection
  
• Click on the Spherical Projection tool. The primitives will look like the images below.
  
• Click on the Validate button.
  6 Hexagon Second Life Sculpties
  • Torus: Cylindrical Projection
  

Click on the [b]Cylindrical Projection tool. The torus will look like the image below. Click on the Validate button.

CAUTION! Once you've used a tool on the primitive, do not remap it! [b]

Using Default Hexagon Primitives

The default Hexagon primitives have no mapping applied to them by default and so will not export as TGA files until they are mapped

While the default Hexagon primitives can be mapped and exported as sculpty maps, their use is not recommended as there may be issues with reversed normals, crumpling, and the mapping will have to be fixed in Hexagon before exporting or in another mapping program to close up any holes in the mapping or move vertices/edges that are off the map area.

Once you use a mapping method (as detailed in "Remapping SL Primitives") on one of the default Hexagon primitives, change to UV View and make sure that no polygons, vertices, or edges are off the edges of the map and that there are no "holes" in the map, i.e., the map must be fully covered.

You can modify the UV in Hexagon or export the OBJ and modify the UVs in UVMapper or other mapping program, then re-import into Hexagon and export as a sculpty map. Check for reversed normals, etc. before bringing into Second Life.

Examples:

Default Hexagon sphere, mapped spherically, exported as TGA, then re-imported into Hexagon: Default Hexagon cube, mapped spherically on Y-axis, exported as TGA, then re-imported into Hexagon: Default Hexagon cylinder, mapped spherically, exported as TGA, then re-imported into Hexagon:

Exporting Sculpty Maps

To export the modified SL primitive:

Choose [b]File > Export > Second Life Sculptie from the menu. A default save dialog will come up. Navigate to the folder where you want to save the file, enter a filename, and click on [b]Save.
9 Hexagon Second Life Sculpties
If you used a default Hexagon primitive and did not map it, you will get the following error message: [b]

NOTE! The Mac version of the exported TGA file may look slightly different than the same one exported from a Win machine, however, it does not seem to affect how the sculpty looks in Second Life although it might slightly affect the rotation of any applied texture. [b]

Texturing the Sculpty Primitive

The sculpty primitive can be textured in Hexagon or in a paint program by exporting in OBJ format then saving the out using UV Mapper or some other program.

You can also used Hexagon's painting tools, then save out the texture by exporting the object out in OBJ format. If you re-import the texture into Hexagon, make sure that the Flip Textures Vertically option is not checked. See the Hexagon documentation for more on using the Hexagon paint tools.

If you apply a texture to the SL sculpty in Hexagon, you will notice a section on the UV map seam (except for the cylinder) that looks similar to the image below:
10 Hexagon Second Life Sculpties

But it looks fine in Second Life. Basically, this is the area at the top and bottom of the that is "blank" and not actually mapped to the object. The only issue is painting in Hexagon and trying to ignore this section at the same time. This appears to be because of the way sculpties are mapped in Second Life and how the Hexagon mapping has to be adjusted to work with the sculpty maps.

And here is the cylinder in Hexagon ... no odd areas in sight.

Importing the Sculpty Map Into Second Life

To import the sculpty map you just created into Second Life:

In Second LIfe, choose [b]File > Upload Image (L$10) from the menu. A default open dialog will come up. Locate the sculpty file, select it, and click on [b]Open. To preview the map as a sculpted prim, click on the [b]Image tab and choose [b]Sculpted Prim from the menu.
12 Hexagon Second Life Sculpties

The object will be visible in the preview window (you may need to zoom in on it). Click on [b]Upload (L$10) to upload the map (this will cost you L$10 to upload so make sure you have the funds available).

The map will be uploaded and a preview window will come up as well. Click on [b]Keep and the map will be placed into your Textures folder in the Inventory dialog.
　[b] 

Applying the Map to a Sculpted Prim

To apply the sculpty map to a sculpted prim in Second Life:

Make sure you are in a location that allows you to build/create objects. Right-click on the ground and choose [b]Create from the pie menu.
13 Hexagon Second Life Sculpties

The [b]Create dialog will come up but don't worry about selecting a particular type of primitive. Just click on the ground to create the default cube.

In the Create dialog, click on the More button if needed.

Click on the [b]Object tab and choose [b]Sculpted from the [b]Building Block Type menu.
14 Hexagon Second Life Sculpties
The default apple sculpty map will be loaded and the sculpty will now look like an apple.
6. Click on the [b]Sculpt Texture box to access the [b]Pick:Sculpt Texture dialog, locate your map, and click on [b]Select. 15

Alles klar!

Die o.a. Objekte benötigen eine spezielle Formatierung, um von "Second Life" erkannt zu werden.
