@Teila Not sure if there would be a conflict with Distingo or RTP... but I really wouldn't think so... Tenkoku is just using normal Unity lights. For the dark shadows you can adjust the 'Ambient Tint' color under configuration tab to be a lighter grey (instead of black), or even shift the hue if you prefer. If this isn't adequate then send me an email and I'll send you back the latest patch fix which will allow you to manually adjust the lights shadow intensity and a few other fixes For the washed out light... you can adjust the light intensity using the Sun 'Light Amount' under celestial settings. This will give you an overboost/underboost depending on the setting. If you need to adjust the tint of the sun lighting this needs to be done in the 'Color Texture', which provides gradient lighting control based on time. Let me know if the above helps or if you still have issues getting the lighting you want. If you can send me (PM or email) a screenshot showing your scene lighting before and after it might help narrow down what specific settings need to be adjusted.
