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.

floyd,

I created the torus manually so that the surface texture could be applied correctly.

Bent and merged solids should not be able to crash Anim8or.

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.

Unfortunately, the UV editor's middle mouse button only seems to change the tiling along the length of the cylinder. Is there any way to persuade it to change the tiling around the circumference?

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.

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.

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.

If you make all of the vertical faces the same width, you could display four different images. This wouldn't work so well in reality because the vertical bars would have to be farther apart than with thin slats. It'd work fine in graphics if you don't mind them interpenetrating.
