Hello, I'm very new to mesh stuff but I always wanted to learn to make things for second life, so I started working on making a mesh horseshoe as a simple practice attempt. I used bolean modifiers in blender to cut out some parts of the horseshoe, and when I do this I get some errors when uploading the file ; 2022-05-11T15:11:19Z INFO # llprimitive/lldaeloader.cpp(2099) LLDAELoader::processElement : Negative scale detected, unsupported transform. domInstance_geometry: cubesx 2022-05-11T15:11:19Z INFO # llprimitive/lldaeloader.cpp(2122) LLDAELoader::processElement : Negative scale detected, unsupported post-normalization transform. domInstance_geometry: cubesx 2022-05-11T15:11:19Z INFO # llprimitive/lldaeloader.cpp(2099) LLDAELoader::processElement : Negative scale detected, unsupported transform. domInstance_geometry: cubefive 2022-05-11T15:11:19Z INFO # llprimitive/lldaeloader.cpp(2122) LLDAELoader::processElement : Negative scale detected, unsupported post-normalization transform. domInstance_geometry: cubefive 2022-05-11T15:11:19Z INFO # llprimitive/lldaeloader.cpp(2099) LLDAELoader::processElement : Negative scale detected, unsupported transform. domInstance_geometry: cubetwo 2022-05-11T15:11:19Z INFO # llprimitive/lldaeloader.cpp(2122) LLDAELoader::processElement : Negative scale detected, unsupported post-normalization transform. domInstance_geometry: cubetwo 2022-05-11T15:11:19Z INFO # llprimitive/lldaeloader.cpp(2099) LLDAELoader::processElement : Negative scale detected, unsupported transform. domInstance_geometry: Cylinderone 2022-05-11T15:11:19Z INFO # llprimitive/lldaeloader.cpp(2122) LLDAELoader::processElement : Negative scale detected, unsupported post-normalization transform. domInstance_geometry: Cylinderone I'm not sure what this means so any help would be greatly appreciated. I tried applying the booleans, I tried saving the file as a wavefront than back to DAE, nothing so far worked.
