AFAIK, you don't need a blend at all...
Just use a glossy transparent material and add your texture as an exponent map...

Yes, Kram has the best way. But exponent mapping on glossy transparent won't be supported until the next Indigo release.

Oh, ok^^
Then, until the next release (thx alot Ono, btw^^), try blending two glossy transparents with different exponents....

Oh and btw - just noticed now, kinda...
Can't see your third pic for some reason

Just me?

OnoSendai: Version 1.1.5 or later?

Kram1032: I'll continue testing as you've specified.

Thanks to two.

Excuseme Kram1032, but the glossy transparents material has not Albedo texture, only Bump Map. Where I put the texture?

Oh, sorry...
use your texture as blend map between two glossy transparent. One with a very high exponent (the one where you see through) and one with very low exponent (the one where you don't see through)

Alternatively, you can replace the high-exponent-glossy-transparent with a specular...

WHat do you mean by between? In the blend material, you can only select two textures.

unless you use a blend which has for textures a phong and a blend....for example...you can get as many textures as you want to ....

I tried using a clip map for a glossy transparent but nothign shows up. My image is pure black text on a white background.

A blend map within a blendmap? Heh, i didnt even know you could do that. I'll give it a look. thanks.
