nPose Sit Pose/Animation Tool – Tutorial

by

nPose is an open source tool for placing and controlling animations in furniture, or other prims which avatars can sit on. The tool has been around since at least 2010. (reference) I need such a tool for a sofa I am making. In my search I found nPose and thought it might be the answer. This tutorial is the outcome of my research. I am writing it in the early stages of my use of nPose, so expect this tutorial to get updates as I learn more. But, it should get you started.

The older nPose v0.028, also labeled as version 1.27, can be found here: User:Nandana Singh/nPose. nPose has had considerable work done on it since then. So, I do not recommend using this version, but it works.

A newer version is discussed here: User:Rev Eponym/nPose. The page does not include a download link. You can get the latest version of nPose at Builder’s Brewery. This SURL should pop you right in front of the vendor for nPose (free), at least as of October 2014.

The in world SL Group for nPose is named: nPose. There seem to be more people online in the SL morning than afternoon. I had better luck getting answers in the morning than afternoon. But, I haven’t been in the group long, so that may not be accurate.

Several people have been involved in advancing nPose. The latest work I found was done in June 2014. So, this is a script I consider under active development.

Second Life Animation Gotcha

by

I ran into this problem a few weeks ago. I even went through a trouble ticket with Gaia Clary, of AvaStar fame 🙂 trying to find what I was doing wrong. Today I filed a JIRA Bug Report: BUG-7185 – Animation Import Failing in ADITI.

I finally imported the problem animation to the main grid and found out it works as intended there. The problem was only on ADITI. The video shows the problem in action.

Second Life – Blender Animation Problem

by

I need to create some poses and short animations for use with an sofa I am making. I’ve been using Blender 2.71a and AvaStar RC3 to make models. So, of course I thought I would use that setup to make my poses and animation. It didn’t work. So, a couple days later I’ve figured it out.

Animations exported from 2.70, 2.71, and 2.71a using any version of AvaStar don’t work… mostly. To explain mostly… I want a pose of an avatar laying on the sofa. In this pose the avatar is reclining and I want the hands on the tummy. Everything worked except the hands. See the image. It shows the hands where I want them.

I rotate the hands about 40-45 degrees in the pose. So, the movement should show up. But, it doesn’t whether I use anim or bvh file types. The hands show in SL with no change from the forearm to hand T-pose positioning.

New Blender 2.71 Weight Painting Video

by

Medhue, of Medhue Animations, has a tutorial video up on weight painting for Second Life using Blender 2.71. The information in general works for any modeling system. But, is specifically for Second Life and Blender w/AvaStar users. While the ideas are transferable to any system, the button presses are specific to AvaStar users. He does not get into Fitted mesh, but for a button press or two it is the same.

There is a commercial in the middle if you watch on YouTube. Its short but it is a surprising burst of sound.

This tutorial is based on Medhue’s work flow, which is very much like the workflow pattern I use. The basic idea is to make one master weight garment or body and then use that for all future weighting. Medhue shows how to do that.

You can discuss the video with Medhue in the SL Forum here: Tutorial – Rigging & Weighting in Blender  2.71 with Avastar for Second Life. (I modified the title a bit…)

The Ditko University in Second Life

by

Update: Ditko University’s in-world location closed May 28, 2014.

Somewhere in the information flowing past me I came across The Ditko University and the classes they teach. Their class schedule is here: Ditko Class Schedule. This item caught my eye: Blender Avastar Animations 101 by Haven Ditko.

I’ve done animations, but my animations (about 6) were done before I got Avastar. While I did a lot of work figuring out animation retargeting last year, I was having a tough time of it. Blender had problems at the time and I am a novice when it comes to animating. So, I wanted to check out this class and make sure I have a good understanding of the basics.

Second Life Animation Sync Problems

by

This video shows problems with animation sync since some Interest List roll outs. Notice the dates changing as the video plays.

A JIRA is being filed today. If you want to file a JIRA on the same problem, please do. Since referencing JIRA numbers other than your own is difficult, make a reference to the July 30 Sever-Scripting meeting and ask your report be referred to Andrew Linden.
