I wonder if anyone out there can help. I've created a detailed model of a lobster in Rhino (obj format and imported in to Poser Pro pack, creating poseable joints etc. Looks great and works perfectly within Poser. However when I export in obj format for use in another program (Bryce5) poser seems not to take long enough_ and then when I try to open the file in Bryce I get the following error " file error has occured (i/o,bad media)" If I export in 3ds Bryce seems happier and will open the untextured/unsmoothed model. I've hunted high and low for problems within the model_ can't find any orphaned polygons etc. Ive created other models which are fine_ this one is larger with over 30,000 polygons_is there a polygon limit in Poser? Any ideas / advice gratefully recieved

did you run it through uvmapper at all? if not try that with the deafult settings (the geometry obj i mean) thats fixed a ton of problems for me......Steve

Thanks Steve, I did prior to setting up the model in Poser (to create the texture map)I had presumed that poser didn't alter the base obj file and that the cr2 did all the poser specific work (ps I'm new to the internal workings of Poser)I will have another look at the obj file in UV mapper and report back.

Steve you're a genius! I didn't really understand what I was doing but had a fiddle with all those (previously undiscovered) 'tools' functions in UV mapper pro and it seems to have solved the bad media problem (I had a few facet and vertices problems)_ My only problem is that small parts of the model look transparent in the poser preview (it renders ok) Does this mean the facet normals are round the wrong way?_ I guess if so I'll have to select them individually in UV mapper and switch them. I'm going to have to do some serious homework on UV mapper_ I hadn't realised it did all that problem solving!!!! Look forward to Lobster thermidor on the Renderosity menu!

it should have been ok if you did in uvmapper before poser as poser shouldn't mess with the obj, but looking at the 2nd message it may have been one of the things you fixed so no worrys as long as it works ;o)......yep that probably means a flipped normal but if it is and you render it white it should show up with black marks around it (unless its detached from the surrounding polys) like this pic... so be careful that its not just invisible coz its at an extreme angle to the camera.....Steve

heyas; that's a nice pic of a shirt with a large burn hole in it, steve. :) uvmapper pro has an 'align vertices' tool (not sure if the preview version has that). although i had to run it several times to finally get all my vertices facing out. that was odd, but it worked.

Yep bloodsong_ looks like Steve was a bit heavy handed with his smoothing iron :) Its funny this inverted normals thing_although my model exports fine now and when rendered you cant see the problematic facets_they are there! The strange thing is when I imported the model in to Cinema 4d (which in facet view mode show the normals as sticky-out-things) they all seem to be pointing the same way. Ah well I suppose the moto is "If it works don't try and fix it"

thats bloodsong didn't realise Steve had got that one going ;o).....yep Noggin if its looking ok just leave it...mind saying that i think they must be the right way around but just at an angle to the camera if c4d is showing them all pointing out (or in in this case LOL)......Steve
