Common/MatDefs/Light/PBRLighting.vert exception in 3.3.0-beta1(after switch from alpha5)

See original GitHub issue

Hi, after switch to new beta1 of 3.3 seems like im getting new issue. i dont think its related to my changes, because i dont trully made any to that Test.

Im using shape keys to manipulate morph shapes of Character models. So its related probably only for morph shapes models.

This refer to:

421	    void Morph_Compute(inout vec4 pos){
422	        #if (NUM_TARGETS_BUFFERS == 2)
423	            Morph_Compute_Pos_Norm(pos,vec3(0.0));
424	            return;
425	        #elif (NUM_TARGETS_BUFFERS == 3)
426	            Morph_Compute_Pos_Norm_Tan(pos, vec3(0.0), vec3(0.0));
427	            return;
428	        #endif
429	        Morph_Compute_Pos(pos);
430	    }
431

below line is problematic:

423 Morph_Compute_Pos_Norm(pos,vec3(0.0));
