Sculptris to blender to unity

Hi, Looking for someone who can help or has had a similar problem. I am working with sculptris to create concepts, sculptris exports in a .obj format but will not import to unity, i get a blank mesh with no verts or tries so essentially no model. I can import to blender and have tried messing with normals, weight painting, adding normal maps, texture maps, bump maps. I have also tried exporting the model from blender in .obj .fbx and .blend (.fbx works for models i made in blender but not for models i imported from sculptris). Thanks for you time any help would be great

are you importing in 2.5 or 2.49?

does your model have any Uvs?

I had an issue importing some objs, (they wouldn’t show an image uv mapped, despite uvs being there…) but when I import in 2.49 and break objects by materials, groups and materials it works fine…

you may not need to do all 3, so try for yourself!

Does Unity have tech support for their obj importer?

I doubt it will work, but sometimes programs don’t like quads so convert to tris?

I converted to triangls, but didn’t work. will try later
