hello. I have just started to learn Maxwell 1.7.1. I am using MXS. When I use emitter materials from the library or create my own from scratch and assign it to surfaces, they don't emit light. I checked all my surfaces' normals and they are ok. When I use physical sky, everything renders normally, but when I turn off environment settings (none), the render is pure black.

also in the console this message appears: "None could not be imported, maybe the material is invalid or repeated". Please note that the result doesn't change whether I use an emitter from the library or create my own.

thanks

check your scene scale and that the emitters (or camera) aren't inside another object.

Also, to note, emitter materials won't work in multi-materials.

Another thing is to check your camera settings. A camera configured for daylight will not show a 40 watt emitter's light.

Well, my scene is an interior shop design, so my camera and emitters are inside a room enclosed by walls and ceiling and floor. Is there a way to rig lighting inside a space?

Also, is there a way to understand whether my camera is setup for daylight or not, because these parameters for the physical camera are a little bit too technical for me.

thanks

Being an enclosed scene is ok. That won't hurt anything. You really do need basic photography knowledge to use Maxwell effectively, though.

Also, is there a way to understand whether my camera is setup for daylight or not...

A *starter* camera setup for interior scenes: ISO 400, Aperture f-stop 2.8 and shutter speed (ss) 30 (1/30th second). With this setup, dof will be quite prominent and to reduce the dof effect, increase the f-stop. With increased f-stop, 4, 5.6, 8, 11, etc., less light enters the camera and so decreasing the ss, 15, 8, 4, etc., and/or going to a faster ISO setting, 800, 1600, etc., is required. BTW, decreasing the f-stop, 1.8, 1.4, 1.2 and 1 allows more light to enter the cameral lens if needed.

To fine tune your camera, start with the f-stop; shutter speed is the next to tweak and finally, ISO. Most of the time with a basic setup, tweaking one of the three will give you a good setup.

add a couple of 0 at your emitters intensity and check again

you can always post your scene here (or part of it) so we can trouble shoot it

I recall seeing a tutorial over at the Think site that related emitter size and strength.

The same emitter applied to a small plane would emit much more light than the same emitter applied to a much larger plane.

Maybe your emitter strength is too small for the size of the plane (or other object) that you have it applied to.
Hope that helps

thank you all, i really appreciate it. Now my lighting looks quite good. I think I should learn how a camera works. Both setting my camera and increasing the watts of my emitters made it.
