Parented hidden objects are visible for raycasts

[ArBuZ]

Hi! Sorry for double post, but by mistake Ive posted it in C++ section and as I expected I haven't received any answer.

I think only Josh can take care of this. But he is must be busy now and doesn't visit that forum section.

Its strange that still nobody have met such problem.

This problem even exists for scene entity.

 

Please forgive me for second same post. But I really need some work around on this problem. Thanks in advanced.

 

 

Here is the problem:

 

If I have an object (for example Cube called "mesh") parented to some other object (another cube called "ground"). In main loop I make ray-cast (camera pick). The both cubes are visible and they are visible for ray-cast.

 

Now I hide the cube "mesh" (the child). And it is still visible for ray-cast!!!

 

I want to hide different parts of some model, and make this parts unavailable for ray-casting, but the rest of the model should be visible and available for ray-casting. And the Scene entity - is a parent of all entities, so I cant hide any scene child from ray-cast.

 

As I understand this problem is consequence of new octree culling system in the engine. But I really need the way as raycasting worked before. Or I will need to do a lot of tricks to make things to work.

 

Here is simple example of the problem.

 

Space - hide the cube. In main loop I make raycast each loop and display the name of picked entity.
