Time for another LDConfig update?

[Philippe Hurbain]

362 Transparent Blue Opal, see https://www.newelementary.com/2020/01/le....html#more
Seems we missed two other colors already available in 2019, 351 Transparent Bright Green with Glitter and 341 Transparent Bright Orange with Glitter (above linked page, at the end)

And another:
364 Transparent Medium Reddish Violet with Opalescence: https://www.newelementary.com/2020/01/ne...edium.html

I don't see these as "Transparent with Glitter".
They look more like a soft, milky, semi-transparent, sometimes pearlecent, plastic.

I think these "new colours" might show a need for Trans colours with values for Alpha, Luminance and Material.
Look at the trans-green Bar 4L and light blue transparent Lightning Bolt part, in the same video review, in the post from New Elementary.

And in the new Trolls sets there's also some parts made of felt or foam.

(I've updated my table above.)

Concerning material, I got one of the fairy-tale books and the book-cover has different surfaces. One glossy one, like the usual parts and partially a bit of a matte finish. Ideally that should be modeled, respectively rendered.

Here is a third opalescent colour, Transparent White Opal, (and lots of new patterned 1x1 tiles)
Interesting part too. Could this be the first part we make using only lo-res prims?

I started drafting it, and had the same thought! the top would perfectly fit the lo res prims :-)

Unless I'm misunderstanding, I would strongly suggest against, since circular primitives represent smooth curves, and this appears to be faceted.

Yes!!! no way to use those prims!

I'd like to resume this thread. BL has new listings:

228 - Satin White
223 - Satin Trans-Light Blue
224 - Satin Trans-Dark Pink
222 - Glitter Trans-Orange

Are these the colors we are looking for?

I mentioned this during the last update of ldconfig.ldr, but unfortunately did not receive an answer.

There have been a significant amount of changes to standard colors last time the file was updated, and I'm wondering if all of these changes were intentional. For instance. The color tan (19) has become very gray-looking:

Previously (#F4DC96):


Latest (B0A06F):



The colors are now less cartoon-like, which is good for realism, but not as good for distinguishing colors in building instructions.

The new train-wheels (38340) are listed at BL as Black, however it is a different black than the ABS Bricks, IMOH it tends to be slightly grayish or even dark brownish. It is a duller material.

Thanks. That explains from where this change comes, but the reason seems to be "Colours were compared with Ryan Howerter colour list.". Does that mean that wherever a color deviated from their list, the LDraw color was simply changed? That seems to have been a rather significant impact. Going back to tan (19) as an example, the previous color seems more accurate when you look at parts in this color.

Yes, I think you're right. But these are the Bricklink numbers. Why should we use them when we know the correct TLG numbers?
228 - Satin White,  seems to be a Bricklink invention. It is not present in Ryan's Colorlist.


We are also missing some Transparent Rubber colours:
This part, 21987/35583
https://www.bricklink.com/v2/catalog/cat...138630#T=C
is made in:
Rubber trans bright green
Rubber trans light blue
Rubber trans red
None of these are in ldconfig.

[Magnus Forsberg]

IMHO, Lasse is right.

Ryan's list is not flawless.

Edit:
Maybe it is. ldconfig is not flawless.

Could you make two new images, using the same rendering engine, but with only different rgb values?

Even better. I can use them both in the same image by modifying my local ldconfig.ldr:

I have a model that will need Rubber Medium Blue on a flex axle, which doesn't seem to be in the config.

Why did you name 10351 "Glitter_Trans_Green"?   Shouldn't it be "Glitter_Trans_Bright_Green"?

[Magnus Forsberg]

Could someone please make a hi quality render using the standard brick 3003?
I want to see what the opalescent colors look like. If they have some sparkling effect at all. Neither LDView nor LDCad can show that.
It looks to me as if they both have difficulties handling the opalescent colours.

Or maybe I should ask: How do I set up POV-Ray export, in LDCad or LDView, to give me decent transparent parts?

[Roland Melkert]

By default LDCad only supports 'normal' transparency. But if Pov-ray can do it you can modify the colors.pov file LDCad uses as an include file to get whatever you need.

I would be interested in any improvements on transparency as it has been a troublesome issue from the start for me to get 'right'.

This is how it currently renders 'out-of-the-box':

It looks good.
And all you changed now was the name of the "Glitter_Trans_Bright_Green" and added "Rubber_Medium_Blue"?

I have codes ready for the Ldcfgalt file.

[Magnus Forsberg]

Here is another interesting colour, or coating.

"Her hair is Light Royal Blue [TLG]/ Bright Light Blue [BL] Mini Doll, Wig, No. 37 (6261350) and is interesting as it has iridescent ink applied as a drum lacquer coating."  
From this review at New Elementary.

Yepp. Checked also the RGB. I however find it odd that Rubber_Medium_Blue. Could also be Rubber_Dark_Azur.

I see that Tan (19) in this latest version is #B0A06F, which is a color closer to dark tan.


This color is unfortunately causing a lot of confusion in building instructions, so I am leaning toward using a hybrid ldconfig.ldr where the color 19 is the previous non-ambiguous value.

I thought so, too—it seemed that, surely, one of the existing colors would be sufficient. But those flex axles do perfectly match the medium blue bricks in real life (maybe just the tiniest shade darker), whereas azure renders as something a tad more greenish.
