I have just made a 3D model on blender and I exported it into a .glb file so I can use it on my PowerPoint, however, when I added it on my presentation on PowerPoint, it is significantly laggier when trying to add an animation to it compared to the preset models on PowerPoint or the ones I’ve downloaded from Sketchfab. I have tried unsubdividing the model and trying to compress the file size in some other ways but it doesn’t seem to work. Can anyone help me please?
Without your file or screenshots of it, we have no way to help you
Welcome 
…
…can you help us to be able to help you ?
For example:
Number of polygons? For yours and for the ones you are comparing?
And for example this:
Is a bit vague… compress ?? Compressing the file doesn’t make the 3D object any smaller (decimate is the keyword).
You may have to elaborate this to get a more suited answer.
Well sorry, I don’t know what word to use and what else to tell you. I’m new to Blender and I’m just trying to get my model to work without lag on PowerPoint. My problem is that I made a molecule using this video https://www.youtube.com/watch?v=zXJKYvuCPYY and exported it to a .glb file so I can use it for PowerPoint but when I use it there, the model doesn’t move around smoothly without lag when adding animations to it.
It won’t let me upload since I’m new, how long do you think it takes before I can?
Minutes… or the forumbot tutorial… see FAQ or your forum inbox…
hmm i checked the faq and it won’t let me upload a file still
It’s some SPAM precaution… so you followed the discobot tutorial… ?? Or you may spent some little more time here than the…

i think this should work now, will this be enough?
Right off the bat, looking at your model…each sphere has been duplicated if you select one oxygen ball and use “H” to hide it in the viewport…there is another under it… It is also very mesh-heavy…way too many subdivisions for a simple scene like this…and you had every instance parented…slows down animation trying to keep up like that…
I fixed a few things and ( Ctrl+J ) on your mesh it now loads 10x faster and moves very smoothly in 3dviewer… ( it’s just an example of a way to get more speed for your presentation…)

Omg, thank you so much! Would it be possible to know how you fixed it so I know what to do next time? I’m new to Blender and I’m looking to learn more of how it works.
Just be careful of your key presses…It seems that somewhere along your modeling you duplicated your geometry, HOW < I don’t know but it can be very easy to do when you go to Shift+S, and accidentally hit Shift + D, something like that.
In object mode, you see something that looks like this
That usually indicates Duplicated Geometry (it’s called Z-Fighting) two or more meshes occupying the same location…Then you need to figure out why it was like that…I usually select at the darker location and hit H to hide in the viewport…If I see the same sphere still but cleaner, then I know…
In this case, using Merge by Distance didn’t eliminate the extra geometry…so had to remove them ( checking the whole model) manually
Then looking at the geometry and seeing the dense faces, I first converted back to quads ( it was triangulated )…then used Unsubdivide a few times Just until I started to see edges on the perimeter…
Selecting one item on the sticks showed me they were all separate geometry ( 1426 of them? ) when each should be one continuous cylinder. That is just a waste of resources…
The dashed lines are relationship lines which is another hint there was something wrong…
All in all…just take your time. Maybe watch some of the beginner tutorials on modeling and basic UI functions to get familiar with Blender…
Good Luck
Happy Blending!
thank you so much for your input!
