thank you, yes there are a lot of features in engine some need adjustament and debugging, a script system can control each element of scene so create traps is simple by write a simpre javascript script, we have inserted now terrain alpha blending painter, thanks to your character we can test engine features.
You can use alpha-blending on terrain not only as material-to-material mix (to prevent looking as separated repeating tiles) but also try light-to-dark mix (and maybe imitation of static lightning system). Some places of terraing must look slightly darken, some lighter. This way even abolutely same tile package will not be looking weird.
