General Anim8or Forum / bug: cuts create spurious surface extensions
« on: March 30, 2009, 12:09:23 pm »
The following sequence of commands causes surfaces to extend beyond their edges. Sometimes this can be "fixed" by additional cuts, other times the cuts cause other spurious surface extensions to appear.

[edit] This bug can be seen in Anim8or v0.97d [/edit]

1. open Animator (in object edit mode)
2. create a cube primitive
3. convert to mesh
4. switch to point edit
5. make two cuts across only the top line
  there now are four points in the top line,
  call them 1,2,3,4 from left to right
6. select the two points at the top right (points 3 & 4)
7. move them upward

bug: a diagonal (grey) surface extension appears between points 1 & 3.
It's an extension of the cube's front and rear surfaces.
This should not have happened: point #2 represents the ends of an edge cut across the top of the cube between the front and rear edges.

Here's a view of the result, with the front rotated down slightly, showing the edges created by the cuts and the inappropriate diagonal extensions of the front and rear surfaces.

The script I've been using to export CMOD models no longer works when run under v0.97b.
No error messages are generated.
It works fine with v0.97a.

The script writes two output files, one listing all materials, the other contains the mesh and vector lists.
An empty material file is written under v0.97b.

The script has not been changed since November 11, 2006.

It's available at http://www.lepp.cornell.edu/~seb/celestia/files/export_cmod_plugin.a8s

When running either Anim8or v0.97a or v0.97b, I discovered that they're generating a script error message when loading scripts but do not indicate what script has the error. All of the scripts listed claim to have 0 errors. See below.

Here's the output seen in the debug window:
