[MagicaVoxel / Bug] Empty/blank shader

[homiczke]

[never mind, i forgot that I have to first select the color(!) then apply shader]

Hello,
I'm using noise shader in MagicaVoxel 0.99.6.2-macos-10.7 I'm sure I'm doing everything right, I've watched some tutorials on youtube and I'm trying to use the shaders exactly the way authors used it, but it's empty and plainly doesn't work. I've tried restarting/reinstalling the program. The particular shader worked before, I used it in the project before.
Help :(
