Invisible avatar instructions using Kokua on Opensim grid simulators.

Secondlife servers provide a default Invisible Avatar as inventory item Library->Body Parts->Alpha Masks->Invisible Avatar. On Secondlife it is easy to use this invisible avatar alpha mask with a rigged mesh avatar to make the underlying mesh visible.
OpenSim does not provide this in its OpenSim Library. There are iar files that can be used to import the invisible avatar to an avatar’s inventory however, this requires access to the OpenSim server console. If there are procedures to perform a client import of an iar file someone please comment. Following the procedure below results in an Invisible Avatar Alpha Mask in your inventory.

Adding an alpha layer when none exists in the avatars inventory.
Right click and select Appearance.
Select Edit Outfit.
In the drop down next to Add More… button Select Alpha.
Since there are no alpha layers in inventory Loading… will be present.
Towards the bottom there is a bar with a gear icon. Notice two text lines icons. The one next to the gear is grayed out. This is for a full inventory display and the selected one next to it is for a filtered display of Alpha masks.
Select the grayed out text lines icon. The entire inventory is now present.
Right click on the Body Parts folder.
Arrow down to new clothes and another menu list will be present.
Select New Alpha Mask.
New Alpha object is now present in the Clothing folder.
Right click and wear the New Alpha. The New Alpha has no alpha mask selected so, there is no change to the avatar.
Cursor up to the upper part of the Edit Outfit panel and under the Body Parts folder select the worn New Alpha.
Select the wrench icon and the Editing Alpha Mask panel will activate.
Enable all five default alpha mask with the check marks next to the alpha texture thumbnail graphics.
The avatar is now invisible. Attachments will still be present.
Select Save As. Name it.
Close out the Edit Outfit panel.
The only thing left visible of the avatar should be a name tag and attachments.
Invisible Avatar may be worn to expose rigged mesh avatars and then taken off as desired.

Note: This procedure could be avoided completely if Opensimulator project provided the Invisible Avatar in its OpenSim Library.
Comments to improve this procedure are welcome.

    I treid going to teh forums to ask a question unrelated to this topic, but got an error page stating …

    SQL ERROR [ mysql4 ]

    Table ‘kokua_phpbb.phpbb_config’ doesn’t exist [1146]

    As to my question …

    Will Kokua become AuroraSim compatible as was promised in the past?

    @Sarge Misfit

    Yes, our forum is down due to a hacked master table. I don’t know if it can be recovered.
    Concerning AuroraSim:
    Some preliminary work was done in September 2012 and a repository of that work is here.

    Work has not progressed because:

    I need a local server to test viewer changes and have been unable to get a response from AuroraSim forum to this there are others having the same issue of not being able to make a local server version of AuroraSim work.
    Not being able to make AuroraSim work on my local machine is a showstopper for me.

    I saw that Firestorm developers are active making FS work on AuroraSim. FS has the resources to develop and test so I think it is best to wait until that work is available publicly and then port from FS to Kokua.

    Thanks, Nicky. I’ve always preferred Imp over Phoenix and hope to be able to say the same of Kokua vs Firestorm.

    Regarding the testing of AS compatibility, Timothy at Zetamex (a new hosting company) is making resources available to viewer developers, not sure if links post properly, but here goes. http://forum.aurorascape.com/showthread.php?tid=60

    Hello! Does anyone know if this alpha layer/rigged mesh business possible somehow with Imprudence at all?? If not, is there a viewer that would allow mesh uploads for free??

  5. NickyP

    Imprudence does not support mesh display or upload but, it is in work. Kokua supports mesh upload and display. Free up loads depend on the grid used. SL Beta Grid aditi charges against a free non transferable Linden Dollar account. Several OpenSim grids charge $0.00 for uploads. That is as close to free that I am aware of.
