Probuilder Advanced 2.9.8f3 Unity 2017.1.0f3 Personnal I still can't autostitch on some faces on all PB Polyshape objects: Mesh.uv is out of bounds. The supplied array needs to be the same size as the Mesh.vertices array. UnityEngine.Mesh:set_uv(Vector2[]) ProBuilder2.EditorCommon.pb_UV_Editor:ApplyUVs(pb_Object, Vector2[], Int32) ProBuilder2.EditorCommon.pb_UV_Editor:RefreshUVCoordinates(Nullable`1, Boolean) ProBuilder2.EditorCommon.pb_UV_Editor:RefreshUVCoordinates() ProBuilder2.EditorCommon.pb_UV_Editor:ClickShortcutCheck(pb_Object, pb_Face) ProBuilder2.EditorCommon.pb_Editor:RaycastCheck(Vector3, Int32) ProBuilder2.EditorCommon.pb_Editor:OnSceneGUI(SceneView) UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr) Is it possible to have an hotfix for that? All PB Polyshape objets have these issues.
