I know that this has been discussed at length, but in the end it seems to me that Addon ConcerterX is the only solution. In US currency $20 is not much, but in our currency it is pricey. Is there another solution?

I have purchased Addon Converter X and does not work for all sceneries. I wish someone to find a solution about this one and only bad problem in DX10 mode.

Which is exactly why I made this thread. There has to be a way to convert these textures manually.
