Member Kaa Posted October 22, 2017 Member Report Share Posted October 22, 2017 Hi, when I import my STL file and use smart materials, the preview fill windows shows correct view. After filling the whole layer, all the model is too dark and not sharp anymore. Any hints? 1 Quote Link to comment Share on other sites More sharing options...
Carlosan Posted October 22, 2017 Report Share Posted October 22, 2017 Hi, Diffuse, specular and normal channels are active ? 1 Quote Link to comment Share on other sites More sharing options...
Contributor Michaelgdrs Posted October 22, 2017 Contributor Report Share Posted October 22, 2017 (edited) Your texture resolution?? And paint channels as Carlosan said. Edited October 22, 2017 by Michaelgdrs Quote Link to comment Share on other sites More sharing options...
Member Kaa Posted October 22, 2017 Author Member Report Share Posted October 22, 2017 Thanks,- too much info for me as a beginner. I made texture resolution 2048. I tried to do the same as in this video: But if I mark the checkbox "Lock normals", the result is a dark model without any contour / (without UV map?) Did the guy on the video has an UV map in his loaded obj-file already? My file is a STL-file... This all happens when importing directly without scene. When importing into a scene, there's no checkbox for "Lock normals"... the result is a model then, which has triangles disturbing flat surfaces,- no sharp edges.

Member Kaa Posted October 22, 2017 Author Member Report Share Posted October 22, 2017 mhmm.... seems so... Actually, there's the only problem on the flat surfaces as on the panel picture above: At the front, You can see the white lines as a cross. This has influence on all layers, no matter what I try,- except "Ambient Occlusion" seems to cover / hide this lines. Meanwhile... I like my wooden Screw: Quote Link to comment Share on other sites More sharing options...
Carlosan Posted October 22, 2017 Report Share Posted October 22, 2017 Which camera projection are you using ? Quote Link to comment Share on other sites More sharing options...
Advanced Member houGenie Posted October 23, 2017 Advanced Member Report Share Posted October 23, 2017 I think you have only one smoothing group on your model. So your normals seem not to be correct. I had the same problem with objects which have hard edges when importing in vortex room. There is no option for normals when importing?

Long time ago, Andrew Shpagin wrote: "Smoothing groups are supported via OBJ format. But you need to export normals also from your 3D-model app. 3D-Coat uses normals in OBJ file to recover smoothing groups." Is it the same until today? My CAD can't export OBJ,- the only mesh export option is STL-format. Any hints? Please note that I am a beginner and I have absolutely no idea about mesh modelling 1 Quote Link to comment Share on other sites More sharing options...
Carlosan Posted November 25, 2017 Report Share Posted November 25, 2017 Hi ! 3D printing uses the geometry as it is, there is no smoothing applied. A lot of 3D software has smoothing applied to the render based on how "light is calculated on the normals, but that smoothing isn't "real" and won't translate to 3D printing.
