hi finally we got this to page 3
normalMaps from cs4 = normal Maps from c4d ?
to export from c4d to away3d, i am using a selfmade awd2 exporter. i am planning on releasing it as soon as i got rid of some minor bugs.
i had a hard time with uv-seams too, but finally it was all about the normals having to be calculated by c4ds-phong tag correctly. i did not encounter any issues with normalMaps, they just worked on first try. (they are not exported via awd2 right now, i have to put them on my model after its loadet in away3d)
edit: when the tangents are off, maybe thats causing the problems. maybe the tangents get auto-calculated before the normalData is set…that could explain the issues. (mesh loadet with autoderiveTangents = true and autoderiveNormals = true, than the normals are set manually (autoderiveNormals = false), but the tangents are still autoderived (but wrong))
to be honest i dont know much about tangents in away3d or any other 3d-app. richard olsen once wrote somewhere that you would nearly never have to set them by “hand”, but they are needed for some of the shading stuff going on under the hood.
