Transparency Tags in .mtl (3dsmax 2012)

TheBat

Heya!

I'm having some trouble with an exported .mtl. The Guruware .obj exporter (3dsmax 2012) exports both the "Tr" and the "d" tag.

The specification (link) says that they're both used for the same purpose, transparency. That they're both exported isn't so much the problem, the real problem is they don't contain the same value!

As you can see in the exported file below, the "d" tag is 1.0000 and the "Tr" tag is 0.0000

	Ks 0.0000 0.0000 0.0000
	Ke 0.0000 0.0000 0.0000

I don't know what to change to make sure that both values are the same. Any suggestions?

Thanks for your thoughts!

Ok, i found out that changing the Opacity in the Material settings changed both the numbers (Turning the opacity down resulted in a lower "d" value and a higher "Tr" value and vice versa).
