Pretty cool! I tested it a bit, it would be nice to have, as a GM, a way to paint an area in one go. Like a paint can function. Also, it would be nice to have some smoothing functions to the brush. I was trying to paint a road for a town and it was a bit stilted. Is there a way to create the sharp cliffs in the demos? my raised terrains seem to be more like hills. A paint can tool would be nice if it could be used on the props as well. Either way, a cool project so far. I'll definitely keep an eye on it. I think, if it were improved, I could see myself using it instead of Roll20.
Hey! Thanks for trying out The RPG Engine and for the very kind words. It's great to hear it's heading in the right direction.
At the moment sharp edges can be created by using a smaller brush around curved top of the slope, this will push the edges out and create more of the effect you are looking for. In future I will absolutely be looking at how to optimise the building process, both in the terrain sculpting as well as the Prop placement (and colouring). There are some things I will be adding first such as a major Ui update, custom item importer and player sheets. After these core elements are in, tools update and many more features will be added!
