Maps, mapping and textures
show user profile  vikki sixx
I have been battling with what is probably a very easy bit of work.

What I want to do is to use a GRADIENT RAMP on a basic texture so that I can simulate something that has a hot glowing tip. To demonstrate my problem I will use a basic Vray material with a mix of Blue and Red and a Gradient Ramp as per my first image. This image shows the two maps that I have used to create the material. It also shows the views of the material on The Material Editor depending on whether the Gradient Ramp is set at UV, VW or WU.

I now create two simple blocks and apply a UVW Map to it, select planar and apply the texture to it, using the three rotations of the material, namely UV, VW and WU. These are the 3 images that I am left with. I am hoping to achieve the results shown in the WU view but alas the top of the block has a horrible purple color (probably from mixing red and blue).

Is there someone who would be so kind as to explain to me what I am doing wrong ?
- is it the way I created the material ?
- is it the way I created my UVW mapping ?
- is it the way I apply my material.

Please help - Thanks

Personally, I would just use a colored gradient ramp - but there are instances where this wouldn't be the best idea. Also, I'd go with UV over the others, because it's easier - just rotate the mapping.

Otherwise, I'm not entirely sure what the problem is. Is that not what you're looking for?
Specialty: Non-organic modelling and effects.
Setup: 3D Studio 2010 with finalRender.
Rig: No, no I can't.

Yeah, you just need to map it right. There's no need to fiddle about with "UV" VW" etc. for this.

Just expanding one of the mapping gizmo's dimensions should do.
