Hello,
I've been having some problems with shadows on a mesh2 obj created on PoseRay
from an .lwo object. The original mesh works fine in Blender, Lightwave and
MeshLab but when I export it as a Mesh2 and render it shadows look hard in
certain areas. Here's the resulting render:

I've used a mesh camera type 3 (which rocks) but result is the same for all
camera types so I guess it has something to do with lighting??
Please let me know if theres a way to correct those shadows. THANKS!

I think the normals may have problems. You can recalculate the normals
in PoseRay's groups tab. Since this is an organic model you may want to
use a crease angle of 180 deg.
PoseRay reads the normals from the input file even if they are wrong. It
only automatically calculates them if they are not present.

Thanks FlyerX. I recalculated the normals. It actually improves the final
result. The surface looks better smoothed but the hard shadows are still there.
I've also tried to scale the geometry *100 but the result doesn't vary. I also
ran some test with a 100% reflective surface and the result came out fine.

THANKS WARP!!
The first link has an easy solution: make the object shadowless by using
"no_shadow". As I'm just using the mesh camera to bake the mesh surface I really
don't care if it doesn't cast shadows. Actually there's no other objects in my
scene. So this solves it for me!!

Actually, this is a very good solution... the only drawback I see is that,
if you are using radiosity, you will get bounces from parts of the scene
that otherwise would have been in the shadow. But you can always use another
instance with the "no_image" flag, I suppose... hmmm, this could be a very
good "general" solution for baking meshes without the "shadow line"
artifact. So, now I've to revise my almost-finished baking tutorial... :)

Is it still your intent to also include your latest in with the
distribution as a sample scene? If so, let me know, and I'll make it happen.
