Vertex Transparency

by Tom Swogger · in Torque 3D Professional · 03/24/2011 (10:48 pm) · 5 replies

I can't seem to get vertex transparency to show up on my imported mesh. Is this supported? I'm using OpenCollada to export my models. I'm using 1.1 Beta 3 of Torque.

Any help is greatly appreciated!

    Is the "vertColor" property set on your material (and the right pass)? If not, vertex colors will be ignored. If it's set, vertex colors will be multiplied with diffuse colors and then interpolated across the polygons which should make your transparency show up correctly.

    I think he's talking about using Alpha vertex information...not (having the vertex color blend down to a texture/materials alpha).

    aka: see through a mesh due to it's alpha vertex information.

    example: 3dsMax -> vertex Paint -> paint alpha (not RGB)

    Yeah, I tried using the Vertex Color flag, it only seemed to work for color, but not vertex alpha. "pain in the butt" is right, I'm trying to get vertex alpha information from 3DS Max to show up in Torque.

    well, Tom Spilman mentioned that it should just work however he did admit that he was unaware if that was the case.

    It doesn't work..if they don't get it into 1.1 then I will snap it in and resource it..(if I am still using T3D at that time).

    This is a very important feature that should take little work to add.

    Awesome, thanks for the response!

    I'll play around with it again tonight. It could very well be the way I'm exporting or something.
