med lab wip
 

here to confuse everyones eyes again with my PLE watermarks!

Ive been working through the med lab scene. The modelling went ok. but its more for the texturing/lighting/rendering that I want to learn. I spent the day yesterday agonisingly sorting out uvs, and I have a question.

When you apply a texture to check the uv layout, i.e, the checkerboard pattern, as seems to be popular and that I used for this, when I see other peoples work, the squares on the checker pattern are always very small and very neat. The squares on mine, lay fine enough, square edges generally running at 90 degrees, but the squares are huge!!. Does this mean that my uv's arent laid out well enough, or is there a way to scale down the texture so that the pattern is more identifiable?

are your UV shells in the area between 0 and 1?

i.e the top right square of the UV texture editor?

You can change the tile/repeat in the 2d-texture node.

hammer horror, - yes they are in there.



how do i find the attributes to change in the 2d node?

ummm... have you unwrapped them?

yeah they are unwrapped. Its just the checker texture comes out very large...

I don't have maya in front of me right now.. so...

Excuse me, but you probably don't have a Texture2D since you used the checkerboard texture... I think it has an attribute something like "checker size" (and color aswell). I guess you assigned the checker to the color slot? So go to the material editor, double click the material and then click the little checker to right.

ok , i changed the coverage in the 2d texture placement attributes in the place2dtexture tab of the attribute editor, which seems to have done the trick. cheers

can you post a screenshot of your uv snapshot?

Also, i would use a checker jpg rather than the checker texture in maya.

uvs

it could be that the shells are just pretty small or that hte maya checker is crap...

i know you have already fixed it, but this would be a good thing to use in future.

thankyou. I can maybe use it for my next steps. ive got some subd surfaces in my scene. how do you go about arranging a uv map for them?

latest shot...

The checkerboard is a good texture to apply to your mesh after you've laid out your uv's to see if there is any distortion going on. To get the small sharp checkers change the repeat u and v to a larger number like 10. (by default I think it set at 4) you'll find that attribute under the "place 2d texture node". Then get to the attributes for the material itself, lambert if thats what your using. Go to the "hardware texturing" attribute and change the texture resoulution to "highest (256 x 256)".

That should do it!
