Octane standalone - decals alpha masking

[iverty]

Hello guys!
I am currently working on some sci fi concepts, and decided to render the images in octane. I got stuck on alpha masking the decals with baked details of the helmet. Once I apply the black and white mask to the opacity slot, plane doesnt seem to be transparent at all, I have been experimenting for a while with the texture parameters, but I didnt manage to get it working properly. Inverting and stuff didnt help, it also changes the way, the material behaves.
I used these maps in blender, and everything was working perfectly.
Id really appreciate your help, in case this is the obvious, super easy matter, sorry for being retarded : (

Maybe 2 geometries too close to each other? Octane doesn't like that.
Try moving them further apart or play with the "Ray Epsilon" setting.

I have absolutely no idea what kind of wizardry is that, but the ray epsilon fixed the issue. I owe you badly, thanks so much for help!
