Member sandman300 Posted February 14, 2016 Member Report Share Posted February 14, 2016 Hello, I've been using 3D coat for a while now, although still feel like a noob. I painted a spaceship in 3DC and everything looked good in the interface; so I exported it using the metalness workflow to lwo. In Lightwave, I get some noticeable stretching of the texture. I thought it might be the UV interpolation. But that is not it. Any idea what might be causing this and how to fix this. I'd post pics but I'm under a NDA. Any help would be most appreciated.

Carlosan Posted February 14, 2016 Report Share Posted February 14, 2016 Do you triangulated the exported model ?

Contributor Michaelgdrs Posted February 15, 2016 Contributor Report Share Posted February 15, 2016 Can you upload a screen shoot as well? Quote Link to comment Share on other sites More sharing options...
Member sandman300 Posted February 15, 2016 Author Member Report Share Posted February 15, 2016 no, but then again I never have before. Tried that, did not help, in fact looks worse. Quote Link to comment Share on other sites More sharing options...
Member sandman300 Posted February 15, 2016 Author Member Report Share Posted February 15, 2016 I would if I could. I'm bound by a NDA. I can upload something else that shows the same problem. the first image is from 3DC, looks good (well enought to show the issue) the second is from lightwave 2015.3 (every thing is stretched) Quote Link to comment Share on other sites More sharing options...
Member sandman300 Posted February 15, 2016 Author Member Report Share Posted February 15, 2016 @ carlosan : looked at those links, I saw them before, I don't think this is a texturing issue. the only changes I made to the lwo after exporting it from 3DC is to change the UV interpolation to Subpatch from liniar (linear was worse) Quote Link to comment Share on other sites More sharing options...
Carlosan Posted February 15, 2016 Report Share Posted February 15, 2016 Could you attach a pic with your export settings ? Quote Link to comment Share on other sites More sharing options...
Member sandman300 Posted February 16, 2016 Author Member Report Share Posted February 16, 2016 This is what I do to export Quote Link to comment Share on other sites More sharing options...
Reputable Contributor digman Posted February 16, 2016 Reputable Contributor Report Share Posted February 16, 2016 (edited) You could be improperly using the "Sharpen Mesh" feature which is designed for when you use a displacement map. It is not designed to be used with a normal map. You have not selected a displacement map for export. Read the tool tip in my Attached image. It might or might not be the cause. I do not use Lightwave. You will have to test by deselecting "Sharpen Mesh" and exporting again. Edit: I added an image that shows the difference between a unsharpened mesh and a sharpened mesh. Model on the left is 3DC viewport and his unsharpened. Model on the right is the sharpened mesh imported into 3DC... look and you will see how the polygon mesh has been altered.

Member sandman300 Posted February 16, 2016 Author Member Report Share Posted February 16, 2016 (edited) Well it seems I can get it to work if I uncheck sharpen mesh and export mid-poly mesh but it adds a lot of weight to the poly counts. it's a difference between 8498 and 543552 polys Edited February 16, 2016 by sandman300 Quote Link to comment Share on other sites More sharing options...

I do know there are a number of Lightwave users that have a good workflow between 3DC and Lightwave...

Member sandman300 Posted February 16, 2016 Author Member Report Share Posted February 16, 2016 I must be doing something wrong then. I watched many tutorials I didn't see any that detail the lightwave workflow. The one that was mentioned earlier in the thread used the PTEX meathod. I always used the per pixle workflow. Is the PTEX better? I wouldn't think so, at least not for what I'm doing. Also I imported a Sub patch object, in the video it looked like regular polys. I never had any problems with other sub patch objects, could it be different since version 4 came out? Quote Link to comment Share on other sites More sharing options...
