After successfully testing FS Skyworld 2004 clouds in FSX, I began to investigate for the water.
In fact, the 1x water looks like the default FS9 water, same kind of color, same sun reflection, etc... For FS9, we had for example the famous morewatr.zip file that would bring some new water textures and colors, and some better reflections, we could get waves reflecting the sun.
I tried it in FSX and but it didn't work, the reflections in 1x mode still look like the default FS9 ones.
For info, I would like to get some waves/reflections like that:

What I have done is rename the OceanHeightField.bmp that can be found in this pack to OceanHeight20field.bmp, like the one that can be found in the FSX directory. The plot is getting at least some nice sun reflections without having to switch to 2x water (too much impact on my video card).
I suppose of course that nobody here cares about that, but I ask anyway: Is it possible at all ?
