How about some tweaks in coming RWE 2 ?
1. Re-compile terrain shader to adopt textures of resolution higher than default 256x256 px at 8 meter grid ? That parameter is the weakest thing in TS since 2008 till nowadays. That's guilty to build a modern, high-detailed scenery and tracks, with awesome textures - and place all of them on blurry, pixelated surface, that has no even bump map support.
2. Add shading capability for TrainFacingFlora.fx . I have a giant collection of low-poly trees possible to adopt to TS and make it look modern and beautiful, but it's impossible to shade their fronds without tweaks. Tweaks look bad at some sun beams angles, and also need extra geometry to cast shadows.
3. Fix procedural grass to be lit by light emitters. Really. So useful feature, not worse than TurfFX in Trainz, which can greatly improve terrain appearance (at least, mask low-res textures under the grass carpet) - and it doesn't work well at night, making all look bad.
I'm ready to donate the job, but as a part of the payware TS utility like RWE only. I don't like the idea people that play for free will take a feature that I've been dreaming for years. Any thoughts?
