ok in the Perspective view it is both i move back and forth... it's just a change of color in the surface ed... if i trun off the subpatches then i don't see the whole eye ball only were there is a hole in the head in Texture. Smooth Shade, flat Shade and when i turn sub patches back on then i only se the outline of the eye ball (the part i didn't see and didn't want to see)... i see the wire outline in Wireframe Shade... which doesn't make senes to me why when i render i see the whole eye ball

Can you post a couple of renders with like 50% transparency on? Like a back and front render?

OK,,,, think i might be butting in,,, but R4s1n is my buddy so guess it doesnt matter... I am curious to why you want to set a face transparent? if you are planning to animate say a ghost or something that need transparency then i think,,,,,, ok. Hmm alright as for the different objects being transparent... I think its simple,,,, just check your transparency value... Make sure its the same. In the picture you can see 2 balls transparent and another without transparency. Both are set to 50 percent so you dont see the part where the both intersect.

Here is the pic

ok this is done at 50%... and every last paeice was done this way... and i put the eye balls on different surfaces

this is from the back... at 50%

this is at 0% from the back

and this is from the front at 0%... this is what i want it to look like but... i want to see the bg thought it... like a ghost

Kumar's second pic is very good at showing what you are trying to accomplish. Just set the same transparency for all the surfaces and render away with the gray background color.

may-be i'm be as dumb as a box of rocks here :P but i set all the surfaces to 50%... is there a place in the render op to do something? in this render... you can really see the inner peice of the nose which is apart of the same mesh of the face... and on the same surface... which is set to 50%... the eyes are on different surfaces and are set exactly the same as the face... but i still see it... in the layout and the modler i don't see it... it's only on a render

Check on your double sided for the surfaces... and you might want to add lights there so that light can travel back to the front

Edit..
Well thats because its trying to calculate the real life senario. So you would want to surface the unwanted mesh parts as like back or unwanted. I use Back,, often.;)

ok this is with the double sided ploys trun on....

Is the color the same on all the surfaces?

Man this is mindboggling :)

Looking better,,, now you can see the back,,, i can see you havent finished it yet. as for the unwanted parts,,, use the 0 percent to turn them off and think you are done.

it is the same color... i tryed filping some of the polys in the eye to see ... it works but you still see but that doesn't help ause you can see it from other angles
