The following notes are taken from the Content Creation User Group (CCUG) meeting, held on Thursday, October 11th, 2018 at 13:00 SLT. These meetings are chaired by Vir Linden, and agenda notes, meeting SLurl, etc, are usually available on the Content Creation User Group wiki page.
Environmental Enhancement Project (EEP)
A set of environmental enhancements, including:
- The ability for region / parcel owners to define the environment (sky, sun, moon, clouds, water settings) at the parcel level.
- New environment asset types (Sky, Water, Day that can be stored in inventory and traded through the Marketplace / exchanged with others.
- Day assets can include four Sky “tracks” defined by height: ground level (which includes altitudes up to 1,000m) and (optionally) 1,000m and above; 2,000m and above and 3,000m and above, plus a Water “track”.
- Experience-based environment functions
- An extended day cycle (e.g a 24/7 cycle) and extended environmental parameters.
- There are no EEP parameters for manipulating the SL wind.
- EPP will also include some rendering enhancements and new shaders as well (being developed by Graham Linden), which will allow for effects such as crepuscular rays (“God rays”)
- These will be an atmospheric effect, not any kind of object or asset or XML handler.
- The new LSL functions for finding the time of day according to the position of the windlight Sun or Moon have been completed, and are more accurate than the current options.
- EEP will not include things like rain or snow.
- It will still be possible to set windlight local to your own viewer.
- Project definition document.
- Project summary (this blog).
- Full EEP Documentation.
- Project Viewer – via Alternate viewers wiki page.
- EEP Feedback forum thread.
- EEP sneak peeks forum thread.
- EEP Jira filter.
- Testing still in progress on Aditi, with test parcels for users still available.
- Test region: Aditi EEP Testing (secondlife://Aditi/secondlife/EEPTesting/128/128/23).
- Parcels cost L$1, but as Aditi funds are provided by Linden Lab, you are not paying for anything with your own money.
- You MUST be using the EEP test viewer why trying to purchase a parcel on the test region – if you are using any other viewer, your purchase will time out.
- Feedback via Jira (bugs and requests) and / or through comments on the forum feedback thread.
- An update to the project viewer is expected soon.
- Graham Linden is continuing to work on the shader support.
Bakes On Mesh
Extending the current avatar baking service to allow wearable textures (skins, tattoos, clothing) to be applied directly to mesh bodies as well as system avatars. This involves viewer and server-side changes, including updating the baking service to support 1024×1024 textures, and may in time lead to a reduction in the complexity of mesh avatar bodies and heads.
This work does not include normal or specular map support, as these are not part of the existing Bake Service, nor are they recognised as system wearables.
The update to the Bake Service to support 1024×1024 textures has run into problems. Anchor Linden is working on fixes for the issues, and once these have been implemented then the viewer should receive and update as well.
The goal of this project is to provide a means of animating rigged mesh objects using the avatar skeleton, in whole or in part, to provide things like independently moveable pets / creatures, and animated scenery features via scripted animation. It involves both viewer and server-side changes.
- Animesh User Guide
- Animesh test content
- Animesh LSL methods:
- Animesh – Updated Limits and Cost Formulas
- Animesh feedback thread
- JIRA filter for Animesh
- The RC viewer updated on October 8th to version 126.96.36.1990211. It had been hoped with would be the last RC version, but issues mean this will not be the case.
- Performance issue: BUG-225584 and forum thread. This is related to the new dynamic bound box used with Animesh. Vir is working on the issue, and Beq Janus from the Firestorm team has been involved in investigations as to the degree of potential impact. There have been one or two sensationalist blog headlines – best to read the forum thread and the bug report.
- Part of the thread has spun away into handling attachments on Animesh. While this is not a part of the initial Animesh release, hopefully the discussions can be split off into their own thread.
- Imposters issue: Animesh objects can imposter independently to avatars. This can result in an avatar rendering normally when seen by others, but any attached Animesh being impostered (or possibly vice-versa).
- This is being fixed so that an Animesh attachment will now have the same imposter setting as its parent avatar. The update will be in the next RC update.
- There is a Mac-specific graphics issue that can result in Animesh objects vanishing from the scene when crossing a region. This is also being worked on.
Animesh and the Marketplace
- There has been some preliminary discussions in the Lab on how to make Animish distinguishable / locatable on the Marketplace (e.g. categories, etc.).
- No decisions as yet, but the Lab is interested in feedback at CCUG meetings or through the Animesh feedback thread.
- Problem here is the risk of confusion cross-over. Do trees animated via Animesh require their own sub-category under “Animesh”, should they have an “Animesh” style sub-category under trees and shrubs (itself already a sub-category of Home and Garden >: Landscaping)?
- There’s also the question of what to call an over-arching category: “Animesh” is a truncation of “Animated Mesh”, and has been used within the project, etc., but those unfamiliar with the project might be confused by it; so might “Animated Mesh” be preferable? A problem here is “Animated Mesh” itself is a little ambiguous in meaning.
- Triangle counts have been suggested as an alternative, but this requires some form of automated count system for items uploaded to the MP, which in turn would require significant changes to the MP tools.
- Even if a tri count could be auto-generated, would people take more notice of it or a given LI?
- A portion of the meeting was taken up with Blender / Maya specific conversations on bone placement for making taller avatars or for use in things like snakes and ropes.
- There was some discussion on altering the axis rotation in the mesh uploader to match the likes of Maya and Substance Painter. As Vir noted in the meeting, there are an array of potential improvements that could be considered for the uploader – but as yet, a specific project hasn’t been defined to it – and any such project would likely be open for creator input.
- Support for additional material maps: there has been various discussions (in the forums, etc), but SL supporting additional material maps – roughness, metalness, displacement, etc. Nothing official is on the table from the Lab, but earlier in 2018, Kitty Barnett did some experimenting with displacement maps with the Catznip viewer – although this should not be taken to mean this is something that will be supported by Catznip or other viewers.
- Vir hopes that Graham Linden will be able to give some thoughts on expanding material maps support in the future CCUG meeting.
