Hi

I’m not totally sure, so sorry if I’m wrong (if someone can confirm), but here is what I think :

The implicit truncation of vector type is when you assign a float3 to a float4 for instance.
The “output parameter ‘o’ not completely initialized” means that you did’nt assigned all the fields of the ‘o’ struct.
And I guess the performane issue is because you are not using the parameter which as the TEXCOORD3 assigned.
