Hi all,
Not sure if this has been brought up before so sorry if it has.
When looking at one of my renders today Ross Crawford commented that the
tracks were to reflective. We worked out that this is because they use the
chrome color (383) to define the metal whereas in real life it is brushed
steel which has a different colour and reflectivity.
As such I propose that a new colour should be created for brushed steel
for use in tracks, train wheels etc. I did some looking and think that
color 446 could be a good candidate as it will look closeish in MLCad and
is currently unused.
|
446 has the yellowish shine to it that I see when I look at track. But
color alone doesn’t solve the reflectivity problem does it? I think you’d
need to also work up some surface settings for POV, right?
I suspect changing reflectivity will do more to improve rendering realism
than changing color but I could be wrong. (as an aside I think everything
is a bit too reflective, no bricks are actually that perfect)

Hi Lar,
I have already done that in POVray (see the bottom of the original post, the
material is much less shiny and a different colour) but I am proposing to
use a new colour as a more general solution so that the new material
definition can be merged into lugnet_colors.inc or other colour definition
files more easily (colour 383 is already processed separately as it is
defined to be chrome rather than a coloured ABS).
|
OK, well sorry, I guess I wasn’t very clear. Would this new color be one that
should also be processed separately/special? By POV? By the cad programs? It
sounds like you alreeady worked up the necessary SURFACE settings (I think
that’s the keyword, I forget)...

It may be me who isn’t being clear. I’ve never dealth with the ldraw side of
colours, just the povray end. Yes it would be processed specially like the
CHROME and RUBBER colours. Perhaps a new definition like METAL could be used
which might also cover electrical contacts (494). Are you thinking of MATERIAL
or TEXTURE maybe? In that case, yes I have worked it out mostly. I’m sure it can
be tweaked some more though.
