Problem:  scaling of point positions doesn't always work in v1.00b

With two sets of points selected at opposite ends (top and bottom) of a mesh and Y axis is selected, applying scaling (moving the mouse up and down vertically) should cause those groups to move up and down, toward and away from one another.  Instead, nothing seems to happen. My impression is that each group is being treated individually instead of as a set: when all axes are enabled, applying scaling using the mouse, the relative positions of the points in the ends contract within each group.

Flattening in the Y dimension has been applied to both sets of end points independently, which might be related.

This works in v0.98: the mesh's end points move up and down.

I've attached screengrabs and a mesh which can be used to demonstrate this problem: vertical scaling works in v0.98 but not in v1.00b

edited to add:

This vertical scaling problem is also present when one starts with a (vertical) cylinder, selects its ends and does an "inset". With scaling selected, the central (selected) inset regions of the two ends won't move up and down relative to one another.

For a long time I've been using models created using Anim8or in my Addons for Celestia (as have other people). Usually my models are rather simplistic and low-poly: I'm not into hyper-realism or adding lots of "greebles" as some people are.

A recent project used particularly simple objects. Distorted cubes became interactive maps and their buttons. It works under Windows, Linux and MacOS.

Another project used quite a few models with somewhat more sophistication to create an interactive notebook. Unfortunately, it works only under Windows.

I need to adjust the location and orientation of the rotational axes of a mesh, but for some reason its origin and axes aren't being shown when the mesh is selected. What am I overlooking or doing wrong?

Thanks!

Is there any chance that the documentation for entering the class parameters for the Ray Tracer could be updated to include some explicit examples?

Although they mention the Attributes menu and list class settings, they don't actually say how and where to enter the various multi-level class parameters.

I'm in the process of searching the forum for posts describing how to use them, and I've found a few, but it's quite frustrating.

In particular, I'm trying to make ripples in a cup of tea look realistic, but it's a struggle.

Soren,

When I ran Pixie3D again, it managed to get past the 71% point. Unfortunately, it's now complaining that my graphics hardware doesn't support the necessary high level shaders (which I suspect might be incorrect), then it crashed when I asked for the debug info.

FWIW, here's what it says in its initial command window:

Starting Pixie3D...
Multi Sample Successfully Supported!
OpenGL has been enabled!
Graphics Card: NVS 3100M/PCIe/SSE2
Max Modelview Stack Depth: 32
Max Projection Stack Depth: 4
Max Texture Stack Depth: 10
Max Texture Units: 32
Max Texture Size: 8192
Max AntiAliasing Samples: 4
Max Clip Planes: 0

==========

I then ran Pixie3D again and did not ask for debug info. It opened a 3D presentation window and I could click on its buttons. However, although the various "create object" buttons highlighted when clicked on, no objects appeared in the window.

While it's initializing, Pixie3 opens a network connection to the IP address 46.30.213.255.

Why?

If it can't open the link, it hangs at the 71% point.

Network connections should not be made without the permission of the user and software should continue to work even if they fail.

See the attached screengrab.
