Okay, I’m trying to make a coin, and have succesfully unwrapped it, made the texture in PS, and applied it to the mesh, which gives me the desired result in the 3d view. However, when i render it, I end up with a texture as if I’ve applied it using the wrong type (cube/flat/sphere/tube etc).
Also, I only want this texture to affect the object as a bump map, rather than appear on it as an image.
Here’s what I mean. I am stumped…
Okay, Just found the ‘Texface’ button and that puts the image on the mesh, but with the radial shading still there that can be seen in the pic above. Trying to follow this: http://blenderartists.org/forum/archive/index.php/t-5250.html to get the texture to affect the normal and not the colour, but to no avail…
Okay, seems that the weird shding if from the ‘smooth’ option, but I till can’t for the life of me get the texture I created from the UV unwrapping to affect the normal.

Since you already unwrapped the mesh and set it up to match uv’s to the image, load the image in your material’s texture channels as an image, and in the mapto panel set to ‘uv’. In the tab that says ‘col’, uncheck ‘col’ and check ’ nor’ and bump up the nor slider to get the surface to bump. Make sure you have enough vert count to do so though.
Hmmm, just made an icosphere, on default settings, set it to smooth, applied subsurf, and got the bump map to work on that…
How many verts is enough? Maybe that’s the problem…
I wrote an entire tutorial on how to correctly bump map a coin a while ago but the moderator never approved it. Kind of disappointing because I did not save a copy of it. I wrote the moderator with a “what’s up” message and never received a reply.
Right, I’ve made another cylinder, with more verts, and re-done all the UV bits and it now seems to work, so perhaps it was a problem with having too few verts…
Thanks for the advice, it got me there in the end…
Not amazing close up, but good enough for what I want to use it for…
TA!
Looks good!!
