i'v got object with 10 parts, parts 1-3 use like collision mask: convex + ignor raycast layer. 5-7 parts, needs only "trigger for raycasts", so, got problems: 1 - error "Non-convex MeshColliders with non-kinematic Rigidbodies are no longer supported in Unity 5.0." but, realy, it's collide nicely (as i need for project, do not touch it please). But this error makes consol as red as USSR (3 error per main object, not collapsed, needs 10-30 objects of this type = 30-90 errors...). If it's about - rigidbody don't coolides BY non-convex mesh with others - ok, all works, but, errors... 2 - if i need mesh, with ONLY raycast collision, but it gets holes etc (convex CAN'T be used) - what i'v need to do? Best solution for this - mesh collider -> trigger, but now i'v cant use trigger without convex... So, what magic i'v need for fix this?
