Using glass effect in the hubsroom, using spoke or blender

[Thitle]

Hi guys, I have a doubt, I have a project under development and I would like to use glass texture. Is there such a possibility? appreciate!

Hi @Thitle - you can have a 3D model that has transparency like glass. For example, a few of the pieces in the architecture kit in Spoke are transparent windows.

Note that these transparencies are sometimes a bit hard on performance, so I would recommend not using too many of them in a space.

Glass and transparent surfaces are some of the trickier things to make work-- not just in Hubs but with the threejs renderer in general (which Hubs uses).
As mentioned in a previous answer, the Architecture Kit in Spoke has some semi-transparent window pieces that use an alpha channel to control the opacity. They are set to 'Alpha Blend' in their material settings. While this works, it's a bit more expensive when running on mobile or lower-powered graphics processors. Also, there are some visual side-effects that may occur when multiple transparent surfaces overlap.
If you use transparency at all, it's best to stick with 'Alpha Clip' mode. It avoids the common side-effects with overlapping transparent surfaces and is much cheaper to render. However, it wont' give you semi-transparency-- only binary "fully transparent or fully opaque" parts.
It's often simpler to just make windows non-existent.
For other things--like maybe a glass bottle or something more three dimensional-- you can use 'Alpha Blend' but be aware of the possible visual side-effects.

I did tests using blender for glass in Alpha blend but when I export to spoke it doesn't really work, would you have any configuration steps for blender?

Thank you, I will test and send news
