Texture and Mesh Exporting crash

The program is crashing every time i try to add texture. it is also unable to export mesh.

Hello asmaa,

what version of RC do you use? Does any error message show up during texturing? If yes, can you post a screenshot?

Can you please specify the error with exporting mesh? Is the button disabled or any error message shows up? In which format are you exporting?

Same problem after updating to latest version. coloring / export xyz is ok but unwarp, texturing, export obj… all crashing.

It gives me this error message. i was trying to export 3D object extension. 

Can you please try to use legacy unwrap algorithm? In the RECONSTRUCTION - Settings - Advanced - Use legacy unwrap algorithm set to ‘True’ and try unwrap again. Thank you
