There is a material that looks illuminated, but does not emit light.
That is to say that at night it has its own lighting but does not participate in the lighting calculation, without radiating light to other objects.
Many times the lamps have their own file or way of lighting, but it is necessary that the light source be illuminated, without that object being the one that produces the light.
Is there such a material or parameters in a material that allow this effect to be achieved?
Para los que entienden en español, por si la traduccion no fue correcta.
Existe un material que se vea iluminado, pero que no emita luz.
Es decir que de noche tenga su propia iluminación pero no participe del calculo de iluminación, sin irradiar luz a otros objetos.
Muchas veces las lamparas tienen su propio archivo o forma de iluminar, pero es necesario que la fuente de la luz se vea iluminada, sin que ese objeto sea el que produce la luz.
Existe un material así o parámetros en un material que permitan lograr ese efecto?
I share the images, family and parameters of the material.
In the images place the lamp with the active IES or without them and only with the led material.
The image “2022-07-23 Material Lamparas 10 Con material 130000 cd m2 y luz IES”, is in my opinion the best. But in that image the LED material has 130000 cd/m2. If I turn off the IES you can see how the LEDs emit light and also participate in the illumination of the image. I don’t know how much this affects the performance of the program, but I think two forms of lighting are duplicated with the same lamp.
In another file that I upload later, this duplication of lighting generated a problem in the video files.
It is not something serious.
What I see is that by raising the intensity of the material that it illuminates, so that the lamp looks more real, this lighting superposition is produced.
The little LED dots are trivial in size. I wouldn’t expect the dots to respond well to self-illumination viewed at a distance. Suggest apply self illumination to the entire surface occupied by the LED dots (shown).
Thanks for sharing, I found a lot of interesting information here. A really good post, very thankful and helpful that you will write many more posts like this one.
