Bump map not appearing on rendered object

Support Materials and Textures

Hello, I am very new to Blender (just a few days using it) and have what I assume is a simple question. I have searched the forums and Google and have been unable to find the answer, although it may just be a matter of not knowing the right terminology for my search queries :slight_smile:

I have been following a beginner’s guide to Blender and so far everything has made sense, but I’ve started running into problems with the introduction of bump maps. The instructions are fairly simple: create a Stucci texture, uncheck the diffuse color influence, check the geometry normal influence, and slide the normal influence way up (I assume to exaggerate the effect). However, when I hit F12 to render, I don’t see any bump map effect. I played with the lighting & camera a bit just in case I had managed to find an angle where the effect wouldn’t be visible but it made no difference.

As a sanity check, I found a Youtube tutorial that also demonstrates simple bump maps and followed the instructions closely but my render looks “blank” compared to the one in the video.

I am wondering if anyone has a guess as to what’s wrong… something with my scene (object/material/texture/lighting/camera), or something with my render settings (which were all left as default), or if there might be a bug or hardware incompatibility issue.

I am using version 2.73a. I’d be happy to provide any other info or a .blend file if it would help.

A few releases ago, the default setting for texture coordinates was changed to UV instead of Generated. You’ll either need to UV unwrap your plane, or change texture coordinates to Generated or Object in the Mapping panel of the texture settings.

Thanks Stan, as soon as I submitted this thread I went back to Blender and started experimenting with the mapping and I found exactly that same solution (setting mapping coordinates to Generated). Unfortunately I couldn’t reply to my own thread stating that I had solved it, because the thread was awaiting mod approval.

The guides I had been following probably haven’t been updated for the changes to Blender. Since one of them was part of a wikibook I suppose I should take it on myself to edit it :slight_smile:

Out of curiosity, how would you UV unwrap the plane, as you put it?

With a plane it’s as easy as selecting everything in edit mode and then Mesh -> UV Unwrap… -> Unwrap :slight_smile: For specific things/images/dimensions Project From View can be useful. Open up the UV/Image editor so you can see the resulting UVs and edit them as needed.
