How to make lighting effect desired objects only?

Hello sir,

I want spotlight to light specific objects only not all.How do i make it do so ?

ThankYou .

It should be a pretty regular problem but there are no tutorials on how to do this.

A common problem would be a lamp shade. How do you simulate light coming through the lamp shade without having it cast the shadow of sed Lamp shade.

An example is of this is my hanging lamp.
I have a point light inside to simulate the bulb light, allowing a concentration of light to hit the floor and sealing. But the light being partially transparent it should allow light to travel though.
I then create a secondary light also inside the lamp. But the only way to allow light to travel though the lamp is to un-tick ‘cast shadows’. This also resulting in no shadows to to cast from the ceiling beams.

In short, to resolve this I would only need to stop the lamp being effected by the secondary light.
But how can I do this???

Don’t know why It posted the image twice…

Did you find a solution??

There used to be lighting channels with UE3 to specify specific meshes but they are not in UE4 (yet?).

@reedandrader

With 4.11 Light channels will return, but only for dynamic objects.

Oh really? They still haven’t implemented this? I have 4.10.4.
