Hello,
I want to boolean union two surfaces together. I have two different textures and every time I try to join them, the other piece just picks the texture of the other object. Is there a way to join two pieces with different textures? Im trying to make realistic modelling for 3D-printing, which requires the objects to be in one single piece.
Thanks
Anybody? 
Hi @Modelling_help
Whast format are you exporting to? Inside Rhino you can use sub-object selection and assign the two materials to each surface, but this will not carry over to eg. *.wrl files. My guess is that your best bet is to either create the UV map manually or - of the slicer allows it - send the two meshes off as separate geometries and let the slicer figure it out. Sometimes it helps to mesh the surfaces as one (inside Rhino using the Mesh command) and then explode them afterwards, apply the right materials and the export.
If this isn’t helping, post more details: What print-format, 3D printer and slicer are you using, what file format and what type of textures (are we talking bitmaps, displacement etc.). Or even better: Post your file!
HTH, Jakob
Hey, meshing the polysurfaces and then doing a meshbooleanunion seems to do the trick. Thanks! Im exporting the files to .stl for the printing.
