Optimising model size anomaly

Question

Hi all,I am trying to optimize a model of a wine bottle for delivery in AR.The base model is built in Sketchup, imported and textured in Dimension before being exported to Aero resulting in a GLB. This process all works.The anomaly occurs when I try and optimise the model and end up getting a significantly larger file out the other end - the original dimension file is 4.6Mb but the "optimised" version is 25.4Mb!My process is simple. Starting with the SketchUp model I reduce the number of faces=3393/edges=6892 to faces=846/edges=1403. Great so far. However, when I use this version to texture in Dimension the result, using the same materials and identical graphics jumps, as mentioned from 4.6Mb to 25.4Mb.I'm a bit lost. I can only guess that dimension doesn't like triangles??? The Sketchup models are shown below  Thank you

i assume what Dimension doesn't like is those triangles being so stretched... try going back to the first model made in SketchUp, import that into a blank canvas and ask Dimension to remap the Uv i.e, select the bottle and auto-generate a new Uv, then give it a basic texture\material and export that model to see how big it is now compared to the other workflow

as a side issue that model will not take a label correct because of that extreme stretching so its value as a mock up is very limited
