Quick help on a MXI, please!

Hi everybody,

I am seting up a scene lit by an emitter material that includes an MXI, but I just cannot make it bright enough. How can I crank up the intensity on a MXI based material?
I know this must be a begginnner's issue, but I have not used Maxwell for a while, and I just can't figure it out. Attached is a picture of 3 materials. All three are emitters and all look dull.

Reopen the MXI in MXCL and up the intensity. Resave the MXI from the file menu and reload into your MXM.

Are you using the sliders in multilight for the emitters?
If so you can adjust past the end of the slider value by typing in 5000 or 10 000 as the value for the emitter.
Other than that you will have to adjust the brightness and resave the mxi or you could do it in photoshop or gimp.

Thanks for the ultra-quick response!

I understand there are no controls for intensity. All depends upon the contrast on the image. But, is there no way to control how much light is emmited from the plane? when I apply the mxi -as it comes- the light intensity is very dim, and it won´t help if I turn it x1000 on the multilight settings post render. In a minute I am uploading a picture. Thanks for all your help.

Here it comes the image. Sliders 4 & 5 are the MXI emmiters. As you can see, they contribute almost nothing to the illumination, altough they are multiplyed by 1000.

you can also type in numbers over 1,000 in multilight. I think you can go upto 10,000 if I'm not mistaken.

Thanks to all for your help. It seems it has been solved by cranking the sliders to 10,000.

Have a nice day!

Remember also if you use Physical Sky it's going to be MUCH stronger than most artificial emitters you have in the scene, MXI or not. So if your camera is adjusted to proper exposure for daylight, your emitters will contribute almost nothing. If you solo out the MXI emitters you get a better idea of the lighting they contribute.
