I tried an old scene that worked properly in uberpov, but I see no 
effect in 3.7.0 or 3.8.0 alpha.

Here are my global_settings:


global_settings
{
	assumed_gamma	1
	#if (Use_Radiosity = 1)
		radiosity
		{
			pretrace_start	0.1
			pretrace_end	0.001
			recursion_limit	2
			count			3
			nearest_count	20,10
			always_sample	off
			maximum_reuse	0.1
			minimum_reuse	0.001
//			no_cache
		}
	#end
	ambient_light	0
//	mm_per_unit		0.4
	mm_per_unit		1/4000
	adc_bailout		0.001
	max_trace_level	8
	subsurface
	{
		samples 5, 5
		radiosity true
	}
}


Here is my finish:

	#declare lg_solid_finish = finish
	{
		ambient	0
		#if (lg_quality >= 2)
			diffuse albedo	0.9
			specular albedo	PlasticSpecularity
			roughness PlasticRoughness
			fresnel on
			reflection
			{
				PlasticSpecularity
//				roughness PlasticRoughness
				fresnel on
			}
		#end
	    conserve_energy
	}


Are there additional settings I am missing?


Mike
