How to ask questions in the blender primstar/jass Group so we can help you
Take screen shots and include the UI (user interface) so that we can
- clearly see the model (usually in edit mode so we can see the mesh frame of the model)
- we should be able to see your Outliner (http://wiki.blender.org/index.php/Doc:2.6/Manual/Data_System/The_Outliner), and UV image edit window
You can upload screenshots (free/no membership) at http://pasteall.org/pic/. The URL will change to the image location once it is uploaded, that is the URL we need to see it.
The other way is to provide your blend file. This can quickly solve many guessing problems.
You can upload your blend file at http://pasteall.org/blend/. Please remember this is a public repository, so use the password function. You can IM me with the URL and password.
Annotating your image can be helpful. A really nice, free one is Skitch (MAC/Windows) available at
JASS (for sculpts)JASS Blender is a build of Blender 2.49, the Python scripting language and Primstar 1.1, the scripts which allow you to work with sculpts in Blender. They are in one package: .exe for Windows, .zip for Mac and Linux. The free version is JASS Pub; other versions are paid editions with more and refined features.
PRIMSTAR 2 IN BLENDER 2.5 AND ABOVE (for sculpts)
If you look at tutorials elsewhere, just make sure they are specifically for sculpts.
My friend, Robin (Sojourner) Wood put these videos together when mesh first hit SL. This remains one of the most cogent explanations of mesh and what to expect in SL.
IMPORTANTTo upload mesh, you must have payment information on file with Linden Labs and take the mesh IP test (each for our grid, Agni, and the beta grid, Aditi, where it doesn’t cost to upload).This seems to be working for getting to the Aditi IP Test: https://secondlife.aditi.lindenlab.com/my/account/mesh-landing.php
To see mesh, you must use a mesh-enabled viewer such as V3 or one of the many TPV (third party viewers) such as the latest Phoenix, Firestorm, Exodus and others.
Important to understand is how mesh is accounted for in terms of how many prims it counts as against your land. It’s called LI or Land Impact.
These tutorials are designed to help you with mesh being produced for use in SL:
To learn about the Blender 2.5x-2.6x interface and various topics on mesh, this is a very useful site:INTRODUCTORY OVERVIEWSAfter you view the overviews, you can search the site for relevant topics.
There are also many topics on YouTube and Vimeo.
Try to find topics for Low Polygon modeling, or high poly methods suitable for use in generating baked textures for you low poly models.
It can be very difficult to answer questions without enough details to point us in the right directions.
Please try to provide the following information that is relevant t your problem.
QUESTION 1Are you doing sculpt or a mesh? Check the section below that pertains to your answer.
2. If a sculpt, are you using a version of Jass Blender with Primstar 1.1 (Jass Pub is the free version) or Primstar 2 in a version of Blender 2.5x-2.6x (and which of these versions; 2.63 is presently the latest)?
3. What sculpt mesh shape did you start with (sphere or cylinder or other? 8×8 with subsurf level of 2, 32×32 with no subsurf)?
4. What were you trying to make and what happened?
5. Did you use any modeling tools such as extrude on your sculpt mesh?
Please try to show us your sculpt set up in edit mode so we can see the mesh (select all verts) and also be able to see the UV Image edit window to see the sculpt map.
2. Which version of Blender are you using?
3. Are you doing static meshes or rigged mesh (avatars or clothing that moves with the SL avatar)?
4. Is the problem with your model in Blender or using the SL Uploader or once you have the mesh in SL.
1. What are you trying to do? What is it doing or not doing?
If your mesh requires a physics mesh so you can walk on floors, not walk through walls and walk through a doorway, you may need to decompose your physics mesh. Please be aware that only Linden Labs has the full Havoc license, at this time, which is what is needed to correctly decompose a physics mesh, so you should use the V3 viewer.
What is Decomposition?
Need a video explanation? Cel Edman, who has some great tools, explains Mesh, Physics and LI (land impact) for SL in these two videos where he goes over the process of decomposition.
Making Mesh Physics for SL:
Recently the Lindens updated the Physics Optimization wiki page. Some good info here.RIGGED MESH:
If you’re brand new to rigging, please make sure you look at the tutorials and information here.
1. What version of Blender are you using?
2. Do you use Avastar?
What is Avastar?
How does Avastar work?
For working without Avastar, you may want to look at the Avatar Workbench:
There are versions of the workbench for the different blender versions; choose the one needed.
3. What problems are you encountering with your rigging?
4. Are you rigging an avatar or clothing? Is the avatar human, non-human or four-legged?
There have been some good clothing tutorials, starting with Gaia’s in the Rigging section (see link above under red Rigged Mesh heading).
Other notables are:
There has been little done in terms of tutorials for hair. For sizing clothing for various sized avatars (since clothing only fits the model it was modeled on until changes come into play), it is suggested that you use scaling, proportional edit, hand editing of points and check the model when done to see if it requires the weighting to be adjusted.
Again, pictures will assist in diminishing the amount of explanation at times and, particularly, the amount of questions we may have to ask in order to understand the problem. Refer to the above-mentioned pasteall site for us to be able to see images that illustrate the problems.
Upload errors can be very frustrating. There is no list of errors (as far as I can find) and often the solutions are as elusive as the errors are confounding. Please let us know if you find good resolution for any particular errors. I believe Gaia feels confident in some solutions and I will list as I as find out what they are.
Remember that it can be important for us to see the model in edit mode (rigged models, not so much) in your images.
It is also good to see the interface and have the relevant editors and buttons and palettes showing.
If you are following a tutorial, please reference the tutorial and the timestamp of where in the video you are having trouble or prompts your question.
If you use Avastar or Primstar 2, please make sure that you have the latest update for the version of Blender you are using. If you have lost or did not bookmark your Inventory page, please visit Jass Island in SL and look for the purple octopus with the Inventory Recovery prim that will pass you your URL again.
