Rough Corner plugin

Box

With Twilight you can add a Texture to the material which will give a Texture to the image.
For example for wood you would add a wood image to the Bump option which would create a wood texture on your wood material. So you could do something similar with your stone corners.

You could do this with the erode plugin. Best round with the round corner plugin before.
Sketchup Plugin Fractal Terrain Eroder. fredo6 round corner(not necessarily)

The looks better, just other parameters

Thanks for the suggestions. Ended up doing a bit of the old "join the dots". Didn't take too long & now I have some rough corner inserts that I can scale/rotate/adjust to customize if needed. The erode plugin works ok too, although I think I like the sharper "chipped" look by doing it manually. Still, forgot I had that erode plugin. Very handy. Cheers Sofie9536

I've attached an Explorer Twilight Render image with the stone materials & I reckon that should just about do it for this job. I could muck around with weld edges etc in TR but not sure if it requires it.

might turn the bump down a little bit in TR actually. Looks a bit rougher than the real thing.

Getting there, roughed up the edges a bit. Starting to look like the real thing. Just need to turn on the water now.

Oh wow, that looks good. Do you mind if I ask what erode parameters you used for that last screenshot?
