00:23 <kintel> Guest49: I believe this particular issue is related to preferences from Qt5 not being compatible with Qt6, and we upgraded to Qt6 not too long ago.

02:38 <Docfxit> Hi,  I have an .scad file with colored text that is defined.  I needed to produce a STL file so I pressed F6.  The colors didn't show anymore.  How can I get the colors to print in Bambu Studio?

03:58 <InPhase> Docfxit: stl does not support colors. Although if your colors disappear when you press F6, you must be using the release and not the nightly build, which has color support for rendering.

03:58 <InPhase> But I don't know what Bambu Studio will read.

04:21 <Docfxit> InPhase: Thank you for the reply.  Where can I find the nightly build?  Should I be saving the file in a different file format to print with Bambu Studio?

04:21 <InPhase> Docfxit: Those are the development snapshots on the download page.

04:26 <Docfxit> InPhase: Thank you.  I will install the development version.

04:28 <InPhase> Docfxit: Make sure you go into the settings and select "Manifold" as your rendering engine. This will be so much faster.

04:28 <InPhase> (On the development version.)

04:29 <InPhase> Like, game changing faster.

04:33 <Docfxit> InPhase: Thank you.  I changed my rendering engine to Manifold.

04:34 <Docfxit> InPhase: I'm now running ver. 2025.06.23

04:38 <Docfxit> InPhase: I exported it as .3mf.  It still lost the colors.  I'm guessing there must be a way to change the text color in Bambu Studio.

05:32 <InPhase> I believe we're still waiting on the 3mf library to release its support for color.

05:32 <InPhase> That should be coming at some point soon, establishing a good standard for color export.

07:52 <teepee> slicers don't show color even if it's defined in the 3mf

07:52 <teepee> that is irrelevant for multi-object slicing

08:12 <J25k96> one way to trigger the color matching in the slicer is to import colors as *.obj

17:25 <sparsh-n> Hi bitbasher sorry I just checked the logs again, I've written a few small updates to the project blog. From the most recent meeting/discussion the current progress is a headless build works, I'm trying to figure out getting vcpkg to install using manifest mode on GH Actions.

17:27 <sparsh-n> ^ nvm, I realized the ping was from the start of june, not end. :)

17:35 <sparsh-n> https://en.wikibooks.org/wiki/Talk:OpenSCAD_User_Manual#Proposal_for_some_updates_to_the_documentation_structure

17:35 <sparsh-n> I'm the anonymous reply haha, I haven't gotten around to making an account on wikibooks. The new (proposed) arrangement/formatting looks good. I remember theres a bunch of disconnected/different ways to view examples/theyre kind of all over the web so having a update there would also be a good addition. But at the same time, maybe updating the

17:35 <sparsh-n> project's README would be of more immediate help.

19:37 <bitbasher> hi folks .. can i get confirmation that the OLD preview renderer was OpenCSG using OpenGL and that Manifold replaces it?

19:39 <bitbasher> and .. how is the snapshot tesselating the model for the "proper" rendering .. and what engine is doin that ?

19:40 <bitbasher> I see some mention of how Manifold is replacing OpenCSG (is that correct?) but i think that is just for Preview??

19:41 <bitbasher> and .. the docs say full up rendering is a two stage process .. or is it three?

19:52 <bitbasher> is it compile then tesselate then render ? and which are the menu options that may be used to trigger each step ? My first read of the docs suggested that Display - F5 did "compile and preview" and F6 the compile-tesselate-better render option?

19:55 <bitbasher> i see output from Manifold in the console when i do an F6 render so that confuses me

19:57 <teepee> no, OpenCSG was and is preview

19:57 <teepee> old mesh engine is CGAL, new one is Manifold

19:58 <teepee> preview does not generally know about any geometry, it's a clever way of painting stuff to look like it did calculate the objects

19:59 <teepee> preview = draw pixel

19:59 <teepee> render = fully calculate the 3d mesh (and display that)

20:01 <teepee> tesselation is not relevant, it's used here usually with the meaning "split complex polygons into triangles"

20:02 <teepee> that's mostly a technical / internal / file-type thing

22:20 <bitbasher> ah ha !! exactly what i needed to know .. and that i had misunderstood. which means that there are some errors in the Wiki docs that i will have to fix .. tomorrow cause i am sleepy now
