hide_object(), children and lamp
04 December 2015 01:33
Hello,
i try to hide an empty with all his children :
it dosen't work, it seems it hides only the empty, not the children.
The same when i try to hide a lamp :
it gives this error :
B4W ERROR: show/hide is only supported for dynamic meshes/empties
The API doc says it is possible :
Check if object is hidden. Supported only for dynamic meshes/empties and lamps.
is it? how do i do?
Thank u

Hello and welcome to the forum.
Could you tell me, please, what version of b4w engine (b4w.min.js) you use? The hide/show methods for lamp objects and children was supported in 15.11 b4w version. I see the old version of console message. In the latest version it is "B4W ERROR: show/hide is only supported for dynamic meshes/empties and lamps".
If you use the latest b4w engine version, please, let me know.

Also, don't forget to enable "Force dynamic object" property on your empty object.

![]()
Hide/show empty with child:
![]()
![]()
Lamp:
![]()
![]()
Hide/show empty with child:
Lamp:

OK,
thanx Roman, you're right :
I started this project on the 15_10 SDK, and it keeps the old b4w.min.js
I replace by the new one and it 's ok!
Thx

There seems to be a problem with hiding lamps with Cycles Nodes, though. Try your example (fresh scene, cube), put a plane under the cube, make a Glossy Shader (GGX) material for the Plane. My result:
Lamp on:
![]()
Lamp off:
![]()
The cube goes fully dark, but the glossy Cycles material on the plane remains visible. Do you get this too?
As a temporary workaround, instead of show/hide, I simply move the lamp back/forth by a thousand Blender units to simulate the "lamp on/off" state. Works fine.
