Anim8or v0.98 Discussion Forum / Large OBJ mesh (4 million vertices) crashes Anim8or build 1185

« on: September 20, 2015, 12:22:17 pm »

What's the maximum size of an OBJ mesh that Anim8or can import?

I tried to import a 724MB OBJ mesh (2Kx2K subdivisions: 4 million vertices) which had been created and exported by Blender, but Anim8or crashed.

A smaller version of the mesh (173MB, 1Kx1K subdivisions: 1 million vertices) imported with no problems.

I'm trying to create a 3D map for use in Celestia. Here are low resolution screengrabs of the 1K mesh with a couple of different surface textures.

Anim8or v0.98 Discussion Forum / BUG: Animator v0.98a [build 1179] crashed when not run as admin

« on: July 28, 2015, 03:01:08 pm »

Bug:

It would be nice if Anim8or did not need to be run once from an Administrator account.

The first time Anim8or (any version, including the most recent v0.98a [build 1179]) was ever run under Windows 7 (x64 Enterprise in this case), it crashed immediately with no error messages when it was run from an account that did not have administrator privileges.

It crashed (with no error popups) every time it was run until it was been run once from a privileged account.

When it was run from an Administrator account, it ran with no errors.

When it then was run from a non-privileged account, it generated an error popup complaining that it could not register a file type but otherwise seemed to work fine.

The next time it was run from the same non-privileged account, no error popup appeared and it worked fine.

My guess is that when it was crashing, it was trying (and failing) to create an entry in the system registry and was not failing gracefully. If that is what was happening, it'd be nice if it tried only to create entries in the registry of the non-privileged user.

Anim8or v0.98 Discussion Forum / Taper modifier distorts textures incorrectly

« on: May 31, 2009, 06:13:25 pm »

Problem:

When a taper modifier is applied to a 16 sided cylinder, the texture
which had been applied to the cylinder is distorted on the result. The squares drawn in the texture are stretched irregularly.

The texture's coordinates should be stretched linearly, just as the
points in the model are.

I tried cutting the cylinder's facets to provide more xyz coordinates
for the texture to be "anchored" to, but that made no difference
whatsoever.

The attached zip file includes a model which has a cylinder before being tapered and the results afterward. I've also included a text file describing how to reproduce the problem.

General Anim8or Forum / Can one change the mouse precision?

« on: May 30, 2009, 07:11:47 am »

Is there a settable option somewhere which can increase the resolution of mouse control?

In the object editor, one can use the mouse to move an object in extremely small increments: placement seems precise no matter how much magnification is being used.

However, this is not the case for rotation, scaling or UV placement. They all have rather coarse increments when using the mouse. This makes it very difficult to orient or size objects precisely.

Scaling and rotation can be set much more accurately when using their numeric menu options, but it usually takes a half-dozen tries for me to find the right values. Also, there seems to be no corresponding set of numeric controls for UV placement. Am I overlooking them?

Anim8or v0.98 Discussion Forum / anim8or crashes when faces are subdivided

« on: May 21, 2009, 06:25:02 pm »

Symptom:
Anim8or v0.97d crashes with no error message: its window simply disappears.

To reproduce:
Load torus.an8 which is included in the attached zip file
switch to point-edit mode
select all faces
select Edit/Subdivide faces (U)

Anim8or disappears without even a *poof*

The zip file includes some comments about how the torus was created.

General Anim8or Forum / how to tile textures around a cylinder?

« on: April 25, 2009, 07:17:49 am »

Is there any way in Anim8or to tile a texture around the curved surface of a cylinder? The UV tool tiles textures but just does face-on projections.

Will I have to create the cylinder out of a bent cube which already has been textured?

Googling the Web and searching the forum didn't find any discussion of this, but maybe I used the wrong search terms.

Thanks for whatever help you can provide.

General Anim8or Forum / Build/Subdivide faces breaks joined solids

« on: April 25, 2009, 06:52:14 am »

When I try to subdivide an object created by joining solids, the original objects are subdivided individually, breaking apart the joined object.

Is there any way I can prevent this, or is it a bug in Anim8or?

I haven't been able to find any mention of this problem in the forum or the manual. Have I overlooked it?

Here's a picture of the result after joining two cylinder meshes and doing a merge points (so there's no gap between the original meshes) followed by a build/subdivide faces. Build/ create subdivided breaks joined solids in the same way.

General Anim8or Forum / bug: cuts create spurious surface extensions

« on: March 30, 2009, 08:09:23 am »

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.

Anim8or v0.98 Discussion Forum / CMOD export script breaks under v0.97b, works with v0.97a

« on: June 20, 2008, 06:09:43 am »

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

Anim8or v0.98 Discussion Forum / v0.97a and v0.97b: error message for unspecified script

« on: June 20, 2008, 05:56:09 am »

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:
