Ray Switch map inside light textmap slot gives strange results

[Slava_Celitel]

Hello !

The problem is rayswitch map inside textmap slot of light.
I uploaded picture where you can see simple configuration

it changes when increasing directionality parameter
strange results in other words.. can anyone confirm that it's a bug ?

P.S

it's adding global illumination value to override value in rayswitch , it shouldn't do it right ?
corona light power is 1
I have "ColonaColor" map  into GI slot of rayswitch - output multiplier is 20
in override slot I have "CoronaColor" map - output multiplier is 2
it gives 20 , while override is 2 .

Hi,
I think it's a known limitation: https://forum.corona-renderer.com/index.php?topic=10864.msg69916#msg69916

thank you for response!
light material in corona and light source is the same thing same behavior .
I just need to make lamp that will emit light value 40 , but in render will appear like 3 to apply bloom on post

I see no other way to just use 2 objects here , 1 object is light source 40 with direct visibility turned off
and then plane object with self illumination material to it , it is extremely inconvenient .. rather than just open more artistic controls on lights.

can I have desired results only using one light ? or only one mesh object ?

Unfortunately, i think for now, two different lights / light materials are the only solution.

First of all thank you for support .

The problem I'm talking is that , to have a light in lamp that meets expectations
I have to create 1 real light source and one plane object , then I have to connect translate rotate and scale parrameters to light
so to make plane translate with light source and then hide light source .
little bit complicated I think for simple light setup .

bad we don't have any other solution.
