@gbz, if the server is set up to use gzip & a .babylon file is registered as a text mime type, transmission compression / de-compression happens at a lower level automatically.
If you wish to get a ball park of the compression, Windows file explorer does quick zip creation by
right click -> send to -> compressed (zipped) folder. Double click resulting to size ratio. DO NOT give the server the zip file. This is just a quick way to see transmission size.
@Ariel_Gimenez , The tags feature is one of the few things someone else did. I know very little about it.
No there is no real time connect. I also worked on the MakeHuman Blender Add-on though. The other person rigged up a localhost:xxxx socket server in MakeHuman, and the add-on is the client. Meshes can be sucked through directly without any import / export involved. Something might be possible, but I am not working on that.
@DeepDeeh, yes either STD or PBR materials can be exported with shadows Must set the custom mesh properties for the caster & receiver meshes of each mesh involved, shown below.
For PBR, environment textures do not contribute to shadows, soshadows can be very faint. You probably need to make the shadows “strong” on the directional light properties, shown below.
Also, you might want to adjust the intensity of the environmental texture down, to make them show up better. The intensity for all materials is set in world properties, but you might only want override to lower the intensity for the material of the mesh receiving the shadow to make it stand out a little more.
