The properties of the inherent metal material seems to have changed quite a bit. I can not seem to keep it from reflecting a lot of light that I would not typically expect to see off of it. Even turning the roughness way up it still seems to have a lot of reflected light around it that seems unrealistic to me. In 2.7 it acted a lot more like I would expect and I am not sure how to get back to that look.

In V3, the Metal Character is using the so-called Material Assistant. So, there is no way to return to the previous behavior, except for creating MXM files; here is the previous logic used to build metals in the plugin, which is just basically a per-type list of Nd, K, and Reflectance 0/90 values, which get applied to a single BSDF (referred to below as "base"):

Code: Select all

if (character.type == "metal")
{
    double nd = 2.0;
    double k = 4.0;
    color metal0 = refl0.toRgb();
    color metal90 = refl0.toRgb();

    if (character.metal == "custom")
    {
        metal0 = refl0.toRgb();
        hsl metal90hsl = refl0;
        metal90hsl.changeLightness(0.15);
        metal90 = metal90hsl.toRgb();
    }
    else if (character.metal == "aluminum")
    {
        nd = 1.143;
        k = 7.135; 
        metal0.assign(167, 167, 168);
        metal90.assign(171, 184, 189);
    }
    else if (character.metal == "chromium")
    {
        nd = 3.21;
        k = 3.3; 
        metal0.assign(151, 152, 152);
        metal90.assign(237, 240, 246);
    }
