Whitewraith: From this page:
I have tried to get the high resolution pack to work . looks great till i get the missile launcher and missing texture. I was wondering if anyone else ran into this?
Please also be aware of the fact that we are still missing models and textures because these have not been remade yet by the community. They will probably be featured in upcoming releases of the HRP.
I think it's just due to the fact that the HRP is a work in progress.
