I make some test and see big difference of size in file.
(in preview left is export with mesh optimiser option, right without )
model is huge 50 000 vertices
original model is in CTM size 357 ko ( ctm is also compress with lzma )
convert to OBJ and in 3dsmax to SEA result face.sea 1639 ko
o3dgc version is good for 1151 ko
so maybe CTM can give a way to lower size in sea3d (source in three.js)
it's just an idea, sea have lot other advantage.
for info face.obj is 12824 ko :)
Thank you! I will check this encoder.
You can using some CTM exporter or the conversion is done out of 3dsmax?
Hmm. The comparation done for glTF is Open3DGC is higher.
I have to move this optimizer to C#(DLL) to be able to do this with big mesh.
