GPU: Issues using triplanar and normal maps.

Hi,

So I have an issue with tri-planar normal map, offsetting slightly from the diffuse, when using identical scaling etc on the tri-planar maps. Needless to say it works fine on CPU. See images, the last one showing the normal on top of the diffuse, you can just make out the offset.

I’m not entirely sure if this happens all the time, but I’ve attached the scene which does have the issue.

Also, there’s something odd with the scaling values, which I’m finding, to get the look i want, I’m having to use 0.001 type values..which it doesn’t like. I cant remember if the scale was getting looked at already? ( I can increase the texture tiling itself but it would be good to not have too)

Thanks.
