Hi all, is there any way in which LW can read an OBJ file format?
could anybody help me with this?

thanks in advance

Yes, it can. In Modeller go to load object, and change the "Files of type" dropdown list to "All Files" instead of "Objects".

Open Modeler's config file with a plain text editor; find "FileType Objects" and add ";.obj" at the end of the line and save.

Modeler will (at the next start) show OBJ files this way. ;)

geoff3dnz and Exper thanks for your tips.
First, I tried sellecting All Documents from the drop down menu.
I can sellect the file, LW crashes as it attempts to open the file.
I will now try Exper's tip. but where can I find the LW config file.
in which directory would this file be on the MAC system

guys, thanks again

If LW crashes loading an OBJ: the OBJ is bad, includes somthing that LW cannot understand or your LW installation has some problems (rescan the plugins from "Edit Plugins" ALT + F11).

Adding the .obj extension to Modeler's Config let you directly see OBJ files (but not solve the crashes).
LW's Config files: go to the directory in which you installed LW, then Programs dir (at least for Win... I didn't used a Mac in the last 10 years).

Hope it helps.

I appreciate you help. I am using sketchUp five. It just got released. One of its export options is OBJ. I am trying to open up the OBJ exported file with LW to render the model with a more realistic appeal. Every time I try opening that file in either LW or Modo, I doesn’t work. I LW it crashes and Modo doesn’t respond.

Now I am able to export it to a 3DS file format, and open the file successfully with LW.
Well, I guess this is good for now. As long as the model opens up, I can get my work done.

Thanks again guys

I had many crashes when opening obj files in LW. Though the obj structure is "standardized", it seems that some interpretations of this structure cannot be read by LW.

I have a file modeled using Milkshape that I could open with XSI and a couple of free programs but LW could not.

just my two cents: I'm using the free DAZ Studio beta, and the, also, free model Aiko 3 LE, and after exporting it from DAZ as obj, it can be perfectly opened in LW, keeping the information on textures and uv mapping, although you've to re-apply the textures using the UV map provided.

Try loading the file into layout (yes, layout can load 3ds/dxf/objs) :)

I have had a few obj files that crash modeler but Layout load them fine. You can then save the object out as a lwo file.

yes, layout can load 3ds/dxf/objs

now THERE'S a cool tip! thx:thumbsup:

Over triangulation

Hi all, I was able to import the a 3DS model to modeler, but the model is over
Triangulated. I have to go over the entire model to merge adjacent polygons.
Is there a way to import the model without it being triangulated?

Thanks

Not in .3ds format - it only works with triangulated polys. If you search Flay for MergeTrigonsX you will get a plug-in that is able to convert triangles into nGons automatically, and very fast on a PC (the Mac version is only a LScript that takes a minutes for about 1000 polys last time I tried).

Yes, but as mentioned earlier, it triangulates the polys, something you *do not* want with an object.

You could try DXF, although that only supports basic geomerty and QUADs. Depends on how complex a model you wish to export.
