Update January 27th, 2013: The Zen viewer has been discontinued by its creator.

Zena Juran released a new version of the Zen Viewer over the weekend – something I almost missed due to being busy with other things in-world (of which I'll say more another time). As mentioned in my original review earlier in the month, Zen is aimed at bringing an enhanced build experience to the V3.2 environment.

Currently still only available for windows, this new release (3.2.8.7) remains based on LL 3.2.8 Development / Project Viewer code, but sees some major changes and additions in terms of the TPV code that has been merged.

Installation and Start-up

The EXE retains more-or-less the same size as the 3.2.8.6 release, and the Viewer installs the same, complete with dedicated user folders and cache locations (rather than using the SL defaults).

Logging-in reveals little in the way of changes between 3.2.8.7 and earlier releases – other than the fact that the UI buttons are no longer transparent (more on this in a moment), the layout is the same as 3.2.8.6 and prior releases. However, open up Preferences, and the updates immediately make themselves apparent.

New Preferences Tabs

In my original review, I commented that Preferences were little-changed from V3.2, but Zena would be adding to the list of capabilities over time. Well, she has – and massively so! At the same time she's also re-arranged things somewhat.

Release 3.2.8.7 sees one tab in Preferences removed (LSL Pre-processing), and five new tabs added, together with an overall re-ordering of things which may initially catch used to operating by wrote a little off-guard (Graphics, for example has gone from near the top of the tab list to fairly well down the order of things). This shouldn't interfere with overall usability, however.

The five new tabs are (in the order displayed:

Name Tags : Pulls together the V3.2 (usually found in the General tab) and popular TPV options relating to name tags (setting colours, etc.) together into a single tab

: Pulls together the V3.2 (usually found in the General tab) and popular TPV options relating to name tags (setting colours, etc.) together into a single tab Shadows : pulls-in the shadow options popular among TPVs, and which can be found in a variety of locations (a sub-tab under graphics, for example)

: pulls-in the shadow options popular among TPVs, and which can be found in a variety of locations (a sub-tab under graphics, for example) Camera : pulls-together "standard" options such as view angle & distance (from MOVE & VIEW), disabling camera constraints (from the Advanced menu), depth of field on/off (duplicated from Graphics), and camera / DoF sliders again found in other TPVs

: pulls-together "standard" options such as view angle & distance (from MOVE & VIEW), disabling camera constraints (from the Advanced menu), depth of field on/off (duplicated from Graphics), and camera / DoF sliders again found in other TPVs Build: presents the Build enhancement tools first seen in the likes of Emerald / Phoenix, and now widely used in TPVs

Visual Auto-Mute

This is perhaps the most interesting change within Zen (and potentially the most drama-risk feature to pop-up in the Viewer code in general for a while), and is the first merge I've seen of a new functionality from LL that was recently released as a changeset (my apologies to other TPVs if they've in fact merged it as well, I'm still trying to catch up on 3 days of missed blogging and updates).

Essentially, this functionality allows you to set thresholds above which avatars with a very heavy load (high-res textures, complex attachments (multiple prims, flexi prims, sculpts, and what have you), etc., – but not scripts, which are a completely different kettle of fish) will not be rendered by your Viewer. Instead, they will appear as "grey ghosts", similar to when you've muted someone; however, you will still be able to IM them and chat with them. This should theoretically reduce the load placed on the Viewer and your system in terms of rendering, and lead to an improved SL experience.

I've covered Visual Auto-mute elsewhere, so will not dwell on it further here.

Graphics Preferences

The Graphics tab in Zen's Preferences has also been updated, with an improved overall layout, largely due to the removal of the low-med-high-ultra slider from the top of the tab (
