Max simul. render targets?

hey gang, I am doing some cool rendering, but need to generate MAPS: albedo, normal, shadow_caster, height, reflectivity, maybe more…

I was hoping to do this in one pass, so each entity can just unload data onto all the maps at once..

I actually re-did the project in DX mode, thinking I would get 8… But I’m hearing now 4 is max?
