New Distortions with Sculpted Prims

I'm having a heck of a time figuring out why my sculpted prims have started showing texture distortions after uploading.

Here's an example showing two sides. This is a relatively simple cylinder prim squashed and deformed a bit in Max, then uploaded using SL Image Upload.

What you see in the first image is the texture not aligning properly. That seam is not on the sculptie however and the texture is not otherwise misaligned. Moreover, the seam that closes this squashed sculpted cylinder is atop the prim as shown in the second image. In fact, the second image shows the opposing side texture skewing to the left (the grey line) so that the seam aligns with the closure point on the opposing edge of the prim.

The sculptie map was generated by Shack's SculptieGen, and I've tested using earlier and the latest versions with no change. This was not happening just a week or so ago, so I'm assuming it's related to the new software (server/viewer).

Does anyone have any idea what's happening here? Is anyone else experiencing this effect? The Max model does not display the distortion. It only appears once the sculptie is rezzed in SL and is visible with the default texture.

Looking at the kind of seam you have there (very sharp, purely in the texture mapping), I can't help thinking that the only issue is with what numbers are in your Repeats Per Face settings in the Texture tab.

By what process are you 'rezzing' the sculpted prim? Did you by chance resize your prim with Stretch Textures unchecked?

Hey Al,

I left the texture widow visible in the second example just to provide a frame of reference on texture settings. No repeats, angular rotations or offsets. There's simply no explanation I can find to explain why the texture is skewing like that. I used a simple floor tile texture on the prim at the size you see. But the default wood texture shows the problem as soon as the sculptie is created, whether the prim type is changed after to a box, cylinder, torus or not.

It's a real mystery to me. I'd sure like to know what's happening though.

Oops, silly of me not to notice that.

I'm amazed that a texture issue like that can happen at all, with such settings. That is, unless there's some hidden polygons ("degenerate" polygons?) in the sculpt shape, but in that case, you'd see a seam in the shading too, visible even if you set the texture to Blank. Not that a viewer glitch couldn't cause that lack of smoothing too; I'm just really hoping it isn't that.

i've been having to add a 0.03 offset to my horizontal offset on some scuptys. looking at yours im thinking you might get a more appealing effect on yours.
