Mudbox mirroring

Valkier

I did a search and found someone with a similar problem but it didn't seem like anything suggested actually resolved the issue.

Basically I import my obj into mudbox, and the mirroring is slightly off to the left. I don't know how to correct it to the center, and using the mirror tangent tool keeps telling me I haven't selected any faces when I clearly have. I tried cutting my model in half, detailing it, then putting it back into max to mirror and weld it, but that too did not work well due to welding too many vertices.

I considered trying to project the normal without the high poly being connected in the middle, but I'm fairly certain that will produce a nasty line running down the center of my low poly.

At this point I'm not really certain what to try and am hoping someone here can tell me. Searching on google is producing nothing, and all the suggestions I found in an earlier topic haven't been working well.

Thanks for any help.

had this problem in ZBrush, so my solution may not be the same since you're using Mudbox...

Make sure the model is 100% symmetrical, down to the vertex locations on the fingers.

Valkier

It's definitely symmetrical. I tried moving the pivot point of the model as well. Still no dice.

Have you made sure that the faces your selecting when you go to fix the mirroring in mud are right along the seam..ie:touching.

Valkier

All right. finally got that sorted out.

Now when I try to bake the high poly onto the low poly with xNormals, I get this.



It's quite obviously nothing like my map. any clues?

Care to show the high poly over the low? This looks like it could be a simple or complex issue

Ged

Ive had lots of problems getting xnormal to export maps, sometimes models export from max/mudbox fine but in xnormal they are sooooo small that the baking will not work so you have to make your mesh about 10 times bigger or even more in the mesh scale options in xnormal. If this still doesnt work then try making your cage mesh a little bigger so theres more distance between your meshes and the cage as well as making the meshes scale larger.

As Ged said, try to scale up a bit the mesh to increase the floating point accuracy.
Also, try to enable the "smooth normals" option.... a lot of subdivision programs don't care about correct vertex normals winding... that should help.

Valkier

Scaled it up and it worked. Thank you ^_^
