I've been using Sams "Odd Tiles Object' include (get it in 
p.b.scene-files) forever and just noticed a problem. The 1st image shows 
the problem ... 2nd image is how is supposed to look.

Builds from the latest uber beta, /and/ povray master branches on github 
have the problem, povray 3.7 stable (github) and perforce repository are 
ok fine.

Is that the "OTOc.inc" 3rd version?

The Sam's test scene (OTOTest.pov) renders fine here with the latest 
POV-Ray and UberPOV stuff (Windows versions).

here's what I'm doing:

#declare Floor =
union {
	object {
		OTO( <-2.5,-2.5,0>, <2.5,2.5,1>, 0.075, texture { BaseTexture scale 1 } )
		}
	box { <-2.5,-2.5,0.075>, <2.5,2.5,0.075> pigment { srgb 1 } finish 
{diffuse 0.6 specular 0.15 roughness 1e-5} }
	rotate x*90
	rotate y*0
	}

kind of funny that it works with some versions (perforce/git 3.7 stable) 
but not other git repos ... 32 vs 64 bit? compiler?? configure changes???

With 3.7.1-alpha.7681813 compiled straight from the GitHub code, the 
above scene snippet (with standard OTO_Object) gives me this:

I stayed out of my local git repos as I've made some changes ... Instead 
downloaded the zip package made available from povray github with the 
master filter selected, it has this hash 
ad6d545729bbd92800fc2d65fe74dcac86408c27 and has the problem. With 
3.7-stable filter set, this hash 
39ce8a24e50651904010dda15872d63be15d7c37 tis ok fine

Well, what can I say, other than "I can't reproduce it"?

Unless you can trim down the thing to an extremely minimalistic scene 
(say, one or two primitives with one or two textures) that is rendered 
differently by the builds you're using, or can nail down exactly what 
GitHub commit broke it, I might be able to do some guessing; but until 
then, unfortunately it looks like I need you to do more experimenting.

That's 3.7.1-alpha.7681813, so same version as I used.

That's the genuine 3.7.0 release proper, aka "3.7.0 stable".

well it's after 3.7-stable for sure ... OTOc.inc sources math.inc dunno 
if that could be a clue.
