VR Hub Update

The VR Hub got a re­design. Jump in­to WebXR games from with­in VR bet­ter than ever!

Ever since its ini­tial “pre­view” re­lease in Oc­to­ber 2018 (al­most 2 years ago!), we planned on im­prov­ing the Con­struct Ar­cade VR Hub.

We en­vi­sion the VR Hub to be an in­vit­ing “home base”, which you re­turn to whenev­er you switch between games. A place that one day may even be cus­tom­iz­able—to make it your own.

Today, we are su­per ex­cited to show you our first steps to­wards that: huge visu­al im­prove­ments and new un­der­ly­ing tech­no­logy.


The VR Hub is where you find what to play next. You re­turn to it after every game! This means that with the help of Won­der­leap we can place ad­vert­ise­ment in form of a non-in­trus­ive poster there.

Mon­et­iz­a­tion al­lows us to con­tin­ue work­ing on Con­struct Ar­cade and put more of our time and ef­fort in­to the plat­form, im­prov­ing your ex­per­i­ence and to bring you more games.

If you you’d like to mon­et­ize your game, find us on the Con­struct Ar­ca­de Dis­cord Serv­er.

Technical Background

The ini­tial ver­sion was already pretty great! We even used light bak­ing for the first time. Back then our bakes with Blender’s Cycles were really noisy, es­pe­cially be­cause the tex­ture res­ol­u­tion was so low that the noise was ex­tremely ap­par­ent.

Now with Basis Uni­ver­sal com­pressed tex­tures, we can have very high res­ol­u­tion tex­tures with low file sizes.

Our new scene has rad­ic­ally high­er tex­ture res­ol­u­tions and we spent way more time on bak­ing the light­ing in Blender to re­duce the noise dra­mat­ic­ally.

This gives us visu­al qual­ity more com­par­able to Moz­illa’s Hello WebXR. Check out their blog post “Visu­al De­vel­op­ment in Hello WebXR!”.

Some baking results for the VR Hub.

The ori­gin­al VR Hub was built on top of A-Frame. Ever since the re­lease of Barista Ex­press, which re­quired cus­tom op­tim­iz­a­tions, we planned on switch­ing tech­no­logy for our pro­jects.

The Con­struct Ar­cade VR Hub is now powered by our WebXR fo­cused game en­gine that we are build­ing to make WebXR de­vel­op­ment more ac­cess­ible to any­one. We will share more info on it soon, so keep an eye out for that on Dis­cord and Twit­ter.

The Future

What we fi­nally re­lease to you today is a great first step for the VR Hub. It is still far away from our vis­ion, though. We’re already work­ing on the next ver­sion.

We really hope you like the new VR Hub.

Best, Jonath­an from Con­struct Ar­cade.
