Transparent Wall error

Hi,

I built a cube and selected the front and back and gave them both the color red.
But when I rotate around the cube the walls are transparent when watched from the back and red when I watch them from the front.

Here are the lines of the rule:

CubeMass-->
comp(f) {object.front:CubeFront|object.back:CubeBack}

CubeFront-->
color(1,0,0)

CubeBack-->
color(1,0,0)

I also provided two pictures.

anybody knows what is wrong?

cheers,

Brian

Hi,

based on the code, you only define front and back. Means top, left, right, bottom are not defined, thus don't generated actual geometry ( no geometry is not the same as transparent geometry .. 🙂 )

ok ?

Sorry, maybe I should have wrote it down more clear 🙂

When I look at the wall from the front it's visible but when I rotate my camera and look at that same wall from the back it's transparent.

already solved the problem.

I disabled "Backface Culling" 🙂

ah..

ok.

that'd have been my next guess, since by default it's deactivated.

glad you found it ..
