Normalize Sizes crash dump - Hank - 09-05-2016 Hello all W3D users, Currently I'm working with quite complicated object and now when I want to UV map it I got W3D crash dump like this: Dump written 2016-9-5_21-7 Version: 1.5.4 Window: {autouv,4} Reason: badarith Short stack trace: [] Long stack trace: [{wpc_autouv,'-handle_command_1/2-fun-4-',3, [{file,"wpc_autouv.erl"},{line,874}]}, {lists,foldl,3,[{file,"lists.erl"},{line,1262}]}, {wpc_autouv,handle_command_1,2,[{file,"wpc_autouv.erl"},{line,883}]}, {wpc_autouv,handle_command,2,[{file,"wpc_autouv.erl"},{line,830}]}, {wings_wm,handle_event,3,[{file,"wings_wm.erl"},{line,825}]}, {wings_wm,send_event,2,[{file,"wings_wm.erl"},{line,797}]}, {wings_wm,do_dispatch,2,[{file,"wings_wm.erl"},{line,698}]}, {wings_wm,get_and_dispatch,0,[{file,"wings_wm.erl"},{line,612}]}] All objects are combined to one and separately had UV mapping. When I select whole object and go to scale -> normalize sizes the error shows up. What cause it? Did I miss some UV or some vertices are too close each other? could you analyse it with attached crash dump? BR, Hank RE: Normalize Sizes crash dump - dgud - 09-05-2016 badarith indicates a division by zero och sqrt of a negativ number, so to small faces/face regions could probably cause that. RE: Normalize Sizes crash dump - Hank - 09-07-2016 True. I did not notice it before but some UV's were deformed during creation. I extruded the faces once again and delete the vertices. Now it's OK. See the print-screen for the root cause: Thanks for the help! BR, Hank.
