Optional image channel are noisy when rendered with mc

[christianbecker3]

Hi everyone!
It seems like that some of the channels are not exported with the additional samples calculated with mc.
Afaik the channels are:

• Diffuse
• Normal (local, not world)
• Shadow
• Specular

Is there a way to fix that behaviour and also is there the possiblity to add more channels for the export (like volumetrics, orbit traps, reflections and so on)?

System information (version)

• mandelbulber2 => 2.30
• Operating System / Platform => Windows 10 - 64 Bit
• Compiler => Visual Studio 2018

Corrected rendering and saving image channels in MC mode. Now the optional channels are averaged in MC mode as main image channels
I will investigate if it is possible to add more channels.
