Tracks Grass washed out without Post Processing

[GT VIRUS]

Hey, just wondering if anyone knows what might be going on here. I am making a track, and the grass looks was too washed out without PP on. The one on the left is with PP, and the other is without. The Diffuse and detail textures have been borrowed from a default track to troubleshoot, but I've tried a couple different textures and it's all been the same result.

It is likely your shader diffuse and ambient are just too high. PP filters can and will auto expose to make it look dimmer than it really is. The idea is to get the brightness correct without PP filters on and then when you turn them back on it should be fine.

Or the specular is set too high and the PP filter boosts those.
