All metalic like textures turn black

I dont know what's going on.
I retried without the others mods (only the dependencies of SSTU) and its doing the same things. Its only a graphic bug since I can combine parts without issues.

I also reduced the graphics settings to see if it was the memory which was unable to load all the textures but got the same result.

Problem resolved
Its render quality settings, I put it in "most fluid", and when I put it in "fantastic" the problem was resolved.

Thanks for the response.

This is being caused by reflections being disabled or unsupported. Likely either an installation error, or other config or loading error, is preventing the reflection system from being used -- by default things reflect 'nothing', which is seen as being 'black'.

Please upload/attach/link to a copy of your KSP.log file -- this file should contain the information needed in order to determine the cause of the problem.
