I'm trying to convert a mesh from LightWave 7.5 to be usable in Poser. After exporting as an obj an importing in Poser5, I found that the mesh had some problem : 1- the light reflected strangely on some part of it. 2- the texture was missing at some parts (under circle, the texture has a "LO" marking, of whoch only the top can be seen here).

Here is a view of the mesh : 1- the mesh as seen in the preview window 2- the mesh as "exported as png". There are transparent facets in it. Can anyone give me a clue as to how to fix this mess ? Thanks in advance for any help you can give me. compiler

The reflection distortion looks like Poser's smoothing. Whenever I export something from LW7.5 to use in P5 I first select any groups of polygons that make up a flat surface and have edges that must stay sharp, and then I cut them and immediatley paste them back in. This splits the virtexes along the edges of what was selected so Poser's smoothing won't go past that edge. I also limit my models to quads and triangles. It looks like the surface with the problem is perhaps a multi-sided polygon beyond 4 sides. I don't know if it has any effect, but you might make a copy of the model and do some experiments on that area to see if either splitting the virtexes at the edges, or reducing the number of edges on the polygon.

Best guess is that you have some reversed normals. One thing that can help is to take the object into UVmapper and export with "no normals" checked. On import into Poser, check "make surface normals consistent."

I loaded the Mesh in C4D 7.3 & everything loads fine. 1. Import the .lwo in C4D. Then arrange the group names. 2. Export it to .obj 3. Open .obj in UVMapper, select all Facets, then Reverse the Normals. (Note: if you get a message after loading the obj that says: "Out of Bounds Vertices...", Do You Want to Correct? Answer NO!) 4. Import .obj in Poser & Voila! You should have a correct model. Of course you'll need to apply the Textures manually for the first time. Hope this Helps!! Marco

Poser cant handle polygons with more than 4 points. So in Lightwave select them with the Statistics window in Polygon mode and use the "Triple" command. Poser only handles UV Texture mapping while LW has many.

Forgot my screen grab...

Well, i just finished Importing & texturing it in Poser. And there's no problemo! Everything renders just fine & the textures are intact. I know what you mean about polys with more then 4 points. But, in this model they are all "Tris" & "Quads". Compiler check your mailbox... :-)) Have Fun! Marco

BTW, i first imported the lwo object in C4D 7.3, then just exported to .obj. Imported in Poser with "Invert normals" ON(Cause C4D inverts the Normals on export to OBJ.). :-) Later! Marco

Thanks everyone for your help. This shows that it's a bad idea to do a modeler's job when you're not a modeler : better ask someone who knows... Thanks a lot Marco !
