Problem can be lighting in powerpoint and you can remove it by editing .pptx file. I tried and I got first black 3D model and then slightly better (I didn’t remove "am3d:ambientLight"). For me this didn’t fix the colors. I tried with PyMol and it’s glTF file
works. Maybe there is something which could be changed in ChimeraX.<o:p></o:p></span></p>

<p class="MsoNormal">For the washed out colors, one problem we have seen before is that macOS uses a special Apple color profile which is not sRGB and if that is not preserved the colors are faded it. glTF does not appear to have support for color profiles.
Another possibility is that the default material in glTF fades the colors. ChimeraX does not export material information into the glTF file. Also glTF can handle camera positions but ChimeraX does not include that.<o:p></o:p></p>

this is an issue on Microsoft's end though?<br>

Hi Mikael,<br>
ChimeraX can save glb, stl, obj, etc. The save formats are listed in the User Guide help page for "save":<br>
<br>
<<a href="http://rbvi.ucsf.edu/chimerax/docs/user/commands/save.html#formats">http://rbvi.ucsf.edu/chimerax/docs/user/commands/save.html#formats</a>><br>
<br>
... or you can list them in the Log with command "save formats." <br>
I hope this helps,<br>
Elaine<br>

Hi! <br>
Is it possible to export 3D models from ChimeraX? Preferably in formats GLB (best for powerpoint), FBX, OBJ or 3MF? You can in old Chimera, but for powerpoint presentations it can only give STL files which do not have textures.<br>
<br>
Here are supported file formats for Office products: <a href="https://support.microsoft.com/en-us/office/3d-content-guidelines-for-microsoft-03a7b493-d549-4f1a-9735-f2457adf6261">
