Just got CC3 world pack last weekend and really like it but having a bit of difficulty figuring out a couple of things. Hoping someone here can help.

1. How do you or can you import your own images as symbols, floor textures or wall textures. I have an extensive collection I've built up in the last few years and wouldn't want to waste them.
2. I was working on doing a cave complex and it has a small river flowing through it. What is the best way to add that. I tried the water but it does a smooth polygon which doesn't look right and I'm not sure how you would feather the edges to make it look more natural.

Any help would be much appreciated. I've spent some time leaching all of your excellent maps off this site and want to be able to give back to the community.

Thanks very much,
