I’m teaching myself blender (v2.5), and so far, it’s been a pretty good experience. I’m using a great tutorial I found on scribd (http://www.scribd.com/doc/8337753/Precision-Modelling-in-Blender) that really appeals to an old CAD guy like me. I’ve made it to about page 69 and now I’m running into trouble with textures.
According to the tutorial, I should end up with this:
Instead, after following the instructions as closely as I could, I get this:
I have a gray material color applied to the bearing’s outer race, but adding the texture, for some reason, turns the base color black. I’ve really no idea where the problem lies, though it’s probably the interface changes between 2.4x and 2.5x require some extra steps that I couldn’t have guessed.
try turning up the exposure in world buttons, or turning up the reflection value of your material, or turning on AO, or increasing the power of your lamp. imo the problem is lack of illumination.
Not entirely sure what your problem is exactly, but it looks like you’re trying to make a reflection map.
Make sure that you’re using “reflection mapping”. In the texture panel click on “generated” and change it to “reflection” or “relf” or something like that (can’t remember exactly)
I’m assuming that the texture is sufficiently light and the lights are sufficiently bright.
Ok, I took a look again and it appears illumination is not the issue, though it did prove to me that the black surface is reflective.
I have set up the mapping coordinates as reflective. I realize I selected “environment map” as the texture type. I switched it to “image / movie” and got better results overall, but the basic gray color of the material is still absent. I proved this by rendering the bearing race with it’s material intensity set to 0.1 and 1.0, with no discernible change in the rendered result.
Attached is the blender file (with deleted geometry to squeeze it in to this post). My apologies for not including it initial posting.
I’m not sure what you’re trying to do here yet. For one you need to pack the image textures into the file. Go File menu->External data->Pack.
If I turn off the Alpha influence in the texture panels the black goes away, but without the images I don’t know if this will work. For some reason I can’t view pages 69-75 of the tutorial, wouldn’t you know it.
I think I figured it out - at least the worst of it.
I took CD38’s hint and started playing with the options in the Influence panel. I ended up changing the diffuse color from 1.0 to 0.5 and viola! the combined effect of the material and the texture. The only difference I see now is that the tutorial’s version is a bit more shiny than mine, which may just mean increasing the diffuse color value a bit more… In any case, I suppose this is close enough…
