Help with bump map

Support Materials and Textures

Hi all!

Have a soft plastic case for a cell phone. Trying to bump map some details onto this case and I’m getting strange results. Clearly I don’t understand what I am doing here.

Here’s the case with bump map:

mat_help
mat_help720×576 77.5 KB

Case without bump map:

mat_help1
mat_help1720×576 72.5 KB

My node setup:

mat_help2
mat_help21680×987 172 KB

and my .blend file:
mat_help.blend (1.2 MB)

Clearly, I’m not doing the bump mapping correctly, but I don’t understand where my problem is…

Thanks for any help,
Randy

Hard to tell without the image packaged with it, but if you just want the visual appearance of the bump, and you have a greyscale image, this would work:

the displacement channel in the material output CAN display as a bump map, but its usually used to drive mesh displacement, and as you’re using Eevee, i’m going to assume you just want the visual display.

Thanks @Jakebane - that fixed it.

I’ve been away from blender for a few years, last version I used was 2.76. I was also a BI render guy… so I guess I have a few things to learn!

Thanks for helping,
Randy
