BI NORMAL CALCULATION USING POD


#1

Dear Team



when i baked a model (render to texture operation) unwrap it correctly i have no problem with the TANGENT CALCULATION use during the deferred process.

But i use a model simply textured without baking i have an error using the tangent .

Sure the data are not present and my question is why…i use the channel 1.

May you tell us what are the requirement to get the tangente and binormal ?



kind regards

david

The solution is to export on channel 0 and it works, i am blind or it s not in the doc :slight_smile:
