xNormal normal maps all blue and doesn't work

mahtikebab

What's wrong with xNormal, I have the most simple scene with 1 high poly cylinder and 1 low poly. The high poly has just one inset ring and one extruded ring. xNormals normal maps generated looks like in the image linked below. Any ideas what's wrong?

Have you set the highpoly model in the highpoly model section? Looks like you're using the lowpoly model as highpoly model.

What mesh format you used to export your model? OBJ? .xsi? collada? 3ds?
Have you setup the cage in a way that it covers completely the highpoly model?

Try beveling/chamfer the edges in your highpoly. You've got only 90* angles which might not work to well with the sampling.

btw mahtikebab, we have a dedicated sticky thread on this forum especially dedicated to xnormal! :P

maybe ray distance?

you just normal mapped a cylinder on a cylinder, you will see no change because the normals are not different. the same would be true for a sphere, it dosent matter if there are 2 billion polies on the high res sphere and 30 in the low res, your normals will be the same. try adding some cuts and bevels in the high if you want to see something on the normal map
