?STL file mesh limits

Questions
1

Hi
Am ‘migrating’ from Java3D to ‘modern’ 3D tooling :slight_smile:
Have got the basics working - But am failing to load a large STL file

moon_lamp_10_inches_refinement_level_360.stl
Have downloaded this from NASA CGI Moon Kit 2019 Moon Lamp by moononournation - Thingiverse

This file fails in my app
Also fails in Babylon sandbox

A medium sized file
moon_lamp_1.33_inches_Y175.stl
available at 1.33 Inches NASA CGI Moon Kit 2019 Moon Lamp by moononournation - Thingiverse

This loads OK in BOTH my App and also in Babylon sandbox

am using ---- code-snippet

assetsManager.addMeshTask(meshTask, , file:, filename);
assetsManager.load();

???Am I hitting some limit within Babylon JS or is there something I can configure/tweak to fix this

Many thanks

Welcome to the forum !!!

cc @bghgary who might know about stl but my guess is that your asset might be to big to handle in web :frowning:

Loading the large file (253Mb) in the sandbox does work for me:

Have you some errors in the browser console log?

Browser console log info as below
Thanks for taking a look at this for me
Have had to cut parts of the log away as too big for these text panes
Let me know if you need the full text of any of the sections

That seems to mean “out of memory” or a driver problem => https://bugzilla.mozilla.org/show_bug.cgi?id=1532525

Checked my Graphics settings
Seems Browser(Firefox) wasn’t making use of the Nvidia Graphics card
Have enabled that & can now load/see the Large file as expected

So I guess the default (Intel) graphics card was not up to the job

Thanks for your time
