Yep, my head never shuts off on this stuff - a problem when it comes
to getting anything in particular done. I wondered this morning about
no_bump_scale and how it gets handled with normals...
The first paragraph of section 3.6.1.2.4 Scaling normals ends with the
sentence: "Think of this like the way no_shadow gets passed on to
objects contained in a CSG." which we know not to be generally true
today in v3.7 or v3.8 - and I expect never completely true.
However, seeing that comment got me thinking about Christoph's statement
about hollow treatments changing v36 to v37 with respect to which shape
in a CSG was used to propagate hollow statements to a CSG result
changing from the first to last - or maybe visa versa.
"Maybe," we could support some limited universal propagation of
no_shadow et al through csg by always propagating always from ONLY the
first object in the csg block? Is this what the pre - v37 coders intended?
In any case. If someone gets the time to dig. Maybe something limited
like a first shape only csg propagation could be supported in v38 which
would be of some help.
