texture mapping Q

[sdds]

Just a quick and maybe obvious question guys.

 

When texturing how do you all go about adding detail like bricks in arches, ridge tiles & bonnet tiles, angle bricks & plinth bricks etc? I guess they can all be modeled without bumping up mesh res much. Also do you all use box and planer uv projection, unwrapping and mapping textures can be a bit of a lengthy procedure, how do you add dirt etc?

Model it ALL I tell ya, Model model model:rolleyes:

 

just joking

apply the texture and throw on a uvw modifier onto the object, select the right mapping(box, sphere, .... ect) and bob's your uncle;)

 

dirt and so on is added mostly in a post production apps like photoshop, either before on the map itself or after on the render, but i guese now with some new 3d features in cs3 most will do it in post

 

unwraping is mostly used for game development where a building needs to be small in file size and the lighting baked into the texture. I would say that a minumum of the people here that does pure arch viz dont unwrap (maybe less that 1%)

thanks for that mate, so your saying just layer up maps using the box, planer uvw's. So for your arch map the basic bricks then flat project the arched bricks on top etc.

Hi,

 

This is what i do for Arched or Voussoir headers:

 

Make an line drawing of a soldier couse header (ie just bricks on edge) to the required width of your window etc.

 

Then take that image into photoshop and I then have some individual bricks of the required type. I then apply these to the outline, transform them to fit etc. Basically I end up with a library of Soldier Header images. I then in max model a box with segements in and then either apply the bend modifer for the arches or a FFD box for the Voussoir. Then all you do is slap on the soldier header with the correct width and apply a UVW map (usually a box). Then as long as the UVW map is below the bend/FFD modifer the uvw map will bend/stretch accordingly.

 

This works a treat and looks pretty accurate. Oh I also create a black & white image in photoshop of my soldier header, plus going over the brick joints in black. This creates a really nice bump map which is pretty natural.

 

Hope that made sense.

No problem mate happy to help. I also forgot to say I do my Soldier Header outline in AutoCAD then just do a print screen and paste that in photoshop. I then save that as a PSD file so I can use it to create other headers of the same width but with different bricks.

 

I can go into more detail on the photoshop side of things as I just explained brifely what I did. I do a few other things to the image as well. If you want more info then you can get me on MSN messenger if you like.
