Hi all,

I was wondering how to make transparent stickers on transparent bricks with opaque print.
Like the windows on the side in set 40252. 



Reading this thread I don't quite follow
https://forums.ldraw.org/thread-22204.html

I thought I'd just make a png image with transparent background and the azure blue triangular shape.
But applying that and make the brick transparent makes the pattern transparent too.

Can I achieve an opaque pattern?

Greetings.  I was surprised to find that BB-8 (or BB-9E) weren't anywhere on a list, and neither were the base parts.  If someone is board, no real need for it, just some pieces that would be good to have done.

Hello guys
i have a main model with a callout. Inside callout i use the command to remove a group

I've been trying to make some stickers for a NES I made in LeoCAD, but everytime I load the .dat file in LDCad, it doesn' work!
   
If someone could tell me what I'm doing wrong, that would be great! Here are some more pictures:

Hi all,

A while ago I posted this thread:
https://forums.ldraw.org/thread-17401.html

Now I am struggling with the annotation for Technic Beams.

I haven't got a clue how to write a regular expression, so is there anyone here who can?

What I am aiming at is that the length of beams is annotated for beams of length 3 or longer and not the lift arms or bent beams.
[Edit]: and including the half or thin beams, but not the modified ones.

Thanks in advance!

[Edit]
Here is the list I want the length to be annotated:

Guys i want to make a very simple custom part. its a rectangle with a png snapped on front with transparent background. its possible to make this? (EASY WAY)

 something like this. its to add into a model in a building instruction. that will be overlapped to a model

This thread is for sharing my learnings and war stories from the LDraw web-rendering project buildinginstructions.js.
You can see how it evolves on BrickHub.org.

Here is a current example of how it renders a LEGO model:



It was not always like this. While there are at least two other web renderers that I know of, I still decided to start this project from scratch. This way I would get practical experience with the technologies involved (WebGL, Three.js, GLSL, etc.), and focus on having performance in mind from the very beginning. While the project itself hopefully ends up being of practical use for many, my goal with this thread is to share my experiences, wins and losses, and perhaps even get some good feedback to help drive the project forward.

The project started in July 2018 with the first breakthrough being in August 1. Back then I had finished an MPV of the .ldr parser while trying to adhere to the Three.js best practices for building a Loader. By modifying one of the Three.js sample files, I was able to get it to render:



As you can see, there were some massive BFC issues, but that was alright for a start. The important part was to get started and get something, anything really, up and running.
My top 3 takeaways from this early stage are:

- Ignore everything that is not absolutely needed in order to get started. This includes conditional lines, quads, BFC, colors, metadata, viewport clipping, etc, etc. While it is important to do things right, the proof of concept both gave me something tangible and came with a morale boost.

- Three.js and the LDraw file format work well together from the perspective of placing things in 3D. It is obvious that James Jessiman knew what he was doing when designing the specification.

- Depending on your approach of design, BFC can be very difficult to get right. There is psudocode in the spec, but unfortunately it did not fit into the data models I had chosen. The pseudocode assumes a single pass of computing both BFC information and triangle wrapping, while my code handles the BFC computation in a separate initial step that creates reusable components.

That is all for the first post. I will try to keep this thread alive with more war stories.

I'm working on a rendering application which requires very accurate models of all LEGO parts.
Naturally the LDraw library is a first stop for me, but I am running into some curious cases of lack of detail even in very common parts like 2xN bricks.
If you look at the underside of a real (modern) 2 x 4 brick for example, you will see a number of small supports, as well as divots where the studs stick out. However, such details are not present in even high resolution LDraw models.

I think it's fair enough if LDraw has some sort of philosophy that the part authors don't worry too much about this sort of detail. But I was just wondering if I was missing anything, or if there was a way to access more detailed part files, especially for very common elements such as these.

Thanks!

Sorry if I'm missing something obvious, guys. I'm now fully-converted to LDCad and loving it, but now that I've completed my first serious model using it (1400+ pieces) I can't seem to find an easy method to get a listing of all the parts used in it. I tried BrickUtils from years ago but it no longer appears to run and I can't quite follow all of the discussion about Rebrickable providing a parts list. Is there no parts list file export directly from LDCad?

Thanks again for all the great work and help!

Hallo community,

I designed an escape pod for my USC MF and wanted to save it in an proper building instruction. So I´m an bloody beginner with MLCad. I send a request to LEGO, about the used color palette. I received this list:
