Texture Mapping curved surfaces

[Jebimasta]

Hey everyone, Im sure this is a well discussed topic, however my searches werent very successful.

I have two cylinders of different diameters connected together so theres a slant between them




Notice how the brushed appearance isnt mapped properly on the slanted edge, Ideally it would remain parrallel to the texture on the cylinders.
Also, the texture breaks at every edge and repeats. I dont think this has anything to do with the smoothing because if you look at this image with a mirror finish material the reflection is smooth.



The material uses a Jpeg as a bump map and the same jpeg as the reflection filter.
Basically if anyone knows how to get good continuity in the material accross the whole cylinder, or how i could map the material properly on the slanted part, that would be awesome.
Thanks

Re: Texture Mapping curved surfaces

Give this free ruby script a try:

instructions for use are on that page.

it sort of projects the map to a curved surface, either cylindrical or spherical. I think for your issue i'd do this:

1. remove all texture from the object in question
2. triangulate the faces of the conical section. this is necessary, as the UV mapping on the cone won't stick when going to the renderer for some reason. this is documented in the Sketchucation thread.
3. soften all the edges if you haven't already done so, the edges between the cone and cylinders don't have to be softened.
3. paint the face(s) with your texture again (hidden lines off)
4. if you kept the edges between the cone and cylinders, select the 3 faces with the select tool now.
5. right click and select "UV Tools" -> "Cylindrical Map".

At least that's what i'd try based on the examples posted. Let me know if that works or you need further assistance.

Re: Texture Mapping curved surfaces

I already have this plugin
I didnt realise the mapping would translate to the vray material too, so didnt considder using it. Daft :P
cheers, I'll give it a go.
