Title: Problem Layered Material - Mask
Post by: mvasse11 on 2021-10-21, 12:16:02
Hi,

I don't know the right methdolody to achieve what I want to do.
I explain, I apply red lines on the floor (picture 01) and I want to mask some part of the line (picture03), but I don't know how to do. I create a mask to try to hide some part, but the result isn't good (picture 02),

To be more precise, I want to hide red line where is the black in the picture 03

If someone know how to do, thank you :D

Hi,

It would help to know what's not good in the result you're getting.

Hello,

You can see on picture 03 the result I want to have, I want to keep red line and just mask the line where I fill with black in the photo :)

So you want that area which is solid red, would be solid black instead?

Not black, just mask to see the concrete texture below

I see. I think the problem is in your layer1 mask, it is all white outside of striped area. It needs to be black where you want that base material would be visible. My suggestion is to remove output node, where you do invert operation, then it should work. You may also need to change blending mode in CoronaMix and/or invert your stripes bitmap, depending on your setup and result that you want.

Alternatively, you can use CoronaDistance map to add stripes and avoid hassle with correct mapping.
