Member uuderzo Posted April 6, 2016 Member Report Share Posted April 6, 2016 Hi all! I'm working on a 3D model of a cave, built with photogrammetry technique from a set of 200+ shots of inside the cave itself. Then, the model was produced with normals facing the inside, and that's what i'm expecting to use for my final result as i need to render the model from the inside. But i have some issues sculpting in 3DC, it happened that it reversed all the normals (i selected the remesh tool). I need to sculpt around rocks to give them more depth and working from the inside will be the more intuituve way. Is there something i can do to ease the process? I attach a screenshot for better understanding. Thanks! Umberto 1 Quote Link to comment Share on other sites More sharing options...
Contributor Michaelgdrs Posted April 6, 2016 Contributor Report Share Posted April 6, 2016 Hi , on similar projects , i cut in parts (left right or top down) or hide the opposite part that blocks my view so i can sculpt / retopo / paint as usual. 1 Quote Link to comment Share on other sites More sharing options...

Thanks Michaelgdrs, I didn't consider that! Anyway, when i import the model from obj format, 3DCoat renders it in a strange way. If looked from the outside, the whole model is rendered fully visible but some polygons over the surface flash continuously, as if the object were composed by two overlapping surfaces with inverted normals. If i look at it from the inside, i see the correct surface as expected. On the other hand, if i import in ZBrush i see it as expected (invisible faces if looked from the outside, ok from the inside, as usual with reversed normal meshes). And, moreover, when i start sculpting from the inside, it suddenly flips the faces and i only see it correctly from the outside. I don't understand what i'm doing to cause it flip all faces. I'm working in surface mode. Quote Link to comment Share on other sites More sharing options...
Member Solution uuderzo Posted April 7, 2016 Author Member Solution Report Share Posted April 7, 2016 Issue solved. All was caused by my misuse of the import mesh tool. I always ended loading the same mesh twice. Cheers! Umberto Quote Link to comment Share on other sites More sharing options...
