artifact on image after save .mxi and reopen

After render is finished image quality is correct but when I save it as .mxi file and reopen it there are white dots and black boundaries around edges.
This is irrelevant from image resolution.

I am using many IES sources there - there could be reason for this bug as I have this scene with less amount of objects and IES and it was fine.
I am using Learning edition v 3.2

You can download mxi here

Here are images png

Correct one - 20160112.png - directly saved after render finished
Image
20160112_broken.png - saved after reopen
Image
20160112_brokenSunSky.png - saved after reopen with only sun&sky lightsources enabled

Hi!

That reminds me of a problem we have with color multilight, but it's been a long time since this problem showed with intensity multilight.

Could you send us the scene without all the geometry but leaving the outside walls, windows and emitters?

In the last image "saved after reopen with only sun&sky light sources enabled" are the rest of the emitters not being rendered or just turned off in multilight?

Thanks!

Fernando

important thing is I enabled color+intensity multilight in 3ds max but in Maxwell Render I am not able to see option to change colors.
On the image with sun&sky I only switch off lights in editor.

Scene exported with pack and go , I saw that IES cannot be loaded but as you have it in pack I hope you will manage it quickly.

I enabled color+intensity multilight
That explains many things. Color multilight has this bug currently.
IES emitters are not supported for color multilight. That's why they are not showing any color box.

At first I didn't notice that it was color multilight. As it was not showing any color box I assumed it was intensity multilight.

If you use Intensity Multilight this won't happen.

In Photoshop plugin there's an action included with which you can play with light colors like in multilight when you open an mxi file.

I hope this helps.

I have tried this and I can confirm that it works. Hope to see color with IES some day.


thanks.
