I want to create an interleaved array, but my model has multiple normals for each vertex, if I create the array interleaved I can only use one normal per vertex. If I average the normals to find the "middle ground per say" how much lighting quality is lost?? Most of my objects are not going to be boxy, so there will be lots of polys. I dont have to interleave the arrays, but I can really cut down on the number of normal calls if I do. So is it ok to average the normals?? Or is that going to be a HUGE lighting quality hit??
