14933	ChimeraX GLTF embedded in PowerPoint has bad lighting	phil.cruz@…	Tom Goddard	"From the March 28, 2024 NIAID ChimeraX meeting:

Phil: ChimeraX gltf outputs look washed out when embedded into Microsoft documents (Powerpoint and Word). Due to their oversaturated lighting model, which is unlikely to be addressed by Microsoft, so we have to try to work around it. I can generate ChimeraX gltf files that look better after embedding in such documents by using different settings in ChimeraX (I have my own preset for this, which uses ""color modify"" to lighten the colors) but that may require yet another set of output options. Kristen: I hacked Powerpoint to get around it but it's not trivial. See this in the forum for the Microsoft lighting: ​https://answers.microsoft.com/en-us/msoffice/forum/all/3d-model-lighting-inside-powerpoint/d0c0c316-8019-4c25-b0f6-86500e512f91 ... The suggested solution is what I've done in the past to fix the lighting.

Meghan: are there ways to fix the gltf after it's output? Blender, but having to download Blender is another barrier. Kristen: maybe NIH3D could have a ""optimize gltf for Microsoft documents"" service that runs our own Blender. Phil, Darrell: it may be a useful utility. Darrell: does gltf outputs from ChimeraX include lights? Kristen: I just checked, and no, these gltf files do not include lights or camera."	enhancement	closed	moderate		Input/Output		nonchimerax		meghan.mccarthy@… kristen.browne@…				all	ChimeraX
