sculpty inside-out

I made a sculpty map by hand in GIMP, setting pixles to calculatd colours, and uploaded with or without uncompressed loading checked. It is a candlestick-like object. It has the right shape, but the texture is applied only on the inside surfaces instead of the outside, which is frankly disgusting. I have tried various versions including ensuring monotomically increasing Z coordinates and not tucking the ends inside (which works with others I have made). None of these worked. So my question is, how does the viewer decide which side of the defined surface to apply the texture to? And how can I alter the sculpty to change it? Apologies if I have missed and existing and/or obvious explanation. If someone tells me how to make the tga file available here, I will do that.

The problem is due to the normals direction ( the way the faces point ) being implied by the pixel order. It's simple to fix

Image - Transform - Flip Horizontal

This reverses the image and thus the normals direction so they point out instead of in.

fantastic ... solved in an instance. Don't suppose there's a clue somewhere how to work out in advance whether it needs flipping? To save upload fees?

You can change the upload preview to sculptured and rotate and zoom the 3D view on that. Should be pretty easy to spot inside out ones before fully uploading.

reversed normals
10-01-2007 22:22
I'm using Wings and trying to get a mirror of an object, of course the normals are reversed and when I flip the image (vertically because the poles of the sphere are oriented that way in my model) it points the normals in the right direction but I get strange artifacts on the poles.
Working with 16x16 to keep it simple, do I have to transfer a row of the bitmap from top to bottom or vice versa to get it to come out right? The points on the poles go beyond or fall short, seems to me. might not be noticeable on a larger image.

Drongle if you're playing with sculpties the Beta Grid is your friend. Free uploads :D

Daath if you enable advanced menus in preferences / advanced you will get a mirror command. Go into face selection mode and select a single face across which to mirror your object, then right click, and *right click* mirror. Wings will generate a mirrored object for you. Woo!

Woo! is right if that works, what you're saying is that 'mirror' automatically reverses normals ... works for me as soon as I verify it ... sounds good tho!

Right if you were trying to mirror with a negative scale you will flip your normals. The mirror command will preserve them. There may be some issue with the exporter, but looking at the result in sculptypaint, it appears to look fine

Thanks, tell you the truth, when I saw the Wings exporter I thought 'keep away from the advanced menu and just deform that sphere' but you are right I think. Wings has some useful stuff and will use it. It works.
