Export tangent space to 3dsmax format

[Rodent]

Hi.

I know that Crosswalk can do it with "Export Tangents as Vertex Colors". How use this vertex colors in 3dsmax as tangent space. My employer has big problems with correctly display models with my normal map baked in XSI.

I found solve for this problem. This is not export tangent space problem. We must invert green channel on normal map. In this way, my model was correctly displayed in 3dmax.

"....One note of caution, you need to invert the up and down channel of the resulting normal map to match the rendering inside of the engine. Open the normal map in photoshop, open the channel section in the layer window, then select the green channel. You'll now need to invert this channel(ctrl+I)..... "
