I am trying to make a part on a Texture transparent so that it is not displayed in the texture file on the final model. Basically a part on the engine needs to not show as the engine type and version has changed and this part is no longer required in the repaint, would an alpha channel make it transparent or would the model need work to make this part disappear?

It depends on the model.Most of the times the alpha layer is resposible for the amout of gloss on the model.Only when a mdl file has an alphadefinition for tranparency , the alphalayer can be used to let parts disappear.Leen de Jager

The Model is the JBSimulations Falcon 20Kevin

I have no idea I do not have the model.Just give it a try.Try to make one alhalayer pure black and see what happens.Leen

In the program Dxtbmp - when you use the option create alpha channel it say's that any pure green will be rendered fully transparent? I have created a pure green layer for the part I am trying to make transparent and then ccombined the two in Dxtbmp to make the texture but it did not work? should I create this layer in Black for this part and then create an alpha channel and combine my master and then then alpha to create the master texture?

Do not use the craete alphalayer option.Just export the alphalayer to your painting program, change it into black 0.0.0 import it back into DXTBmp and save the file.
