I have new problem couldnt find any solution in Google ... im using a qml file and it contain a surface3d , when i show it with a obj file that was in qt examples (oilrig) it could show correct without any problems!

but when i used my own obj file (boat) it couldnt show correct in surface3d application (showing with grid Triangles, not like a volume ...)

my own .obj (wavefront export) file .obj (wavefront export) file from qt examples

in blender(a program for editing 3d models) my boat and oilrig has correct views but in surface3d just oilrig is true! i tested 100 items more that downloaded from internet but cant work , just oilrig that was from qt examples was true can any one help me????

  • looks like you have some problems with normals. try to clear scaling/rotating (Ctrl-A) in Blender and check the model normals. – folibis Jul 09 '20 at 11:18

ok i found a Temporary solution that was usefull for me.

1- convert that model in blender to ".dae"

2- upload it in scene editor online

3-convert it to Model (from NULL)

4-export as .obj file and use it in QT ^_^
