Thanks for the reply so far!
I will admit I'm trying to avoid a roll out mat. I really like painting the terrain, i did a diorama for my gundam models recently and was super pleased with the results. I'm hoping i can recreate the look and feel of a paper map while also having 3d terrain. I'm not sweating the water for sure. And i really want to avoid flocking as much as possible
What is your experience with plexi that turns you away. I got a small sheet of this optix stuff from lowes. It seems durable and when i used to work there is was a real B to cut. I feel like a 3/32+1/8 sheet would be pretty resilient? And i can get nice sizes to paint up. I feel like bowing might be an issue and I'm currently brainstorming a work around for that. I doubt the bond on acrylic paint would be sufficient to mount a piece of FRP. (that clipboard like brown paneling)
Years ago I made a hex template using plexiglass.
It was the higher quality stuff .
I marked out ALL of the spots needed to drill enough holes to replicate an entire
Battletech board scaled to 1.5 inch hexes . ( To match the Geo-Hex Battlescape terrain )
I then drilled hundreds ,maybe thousands ,of 1/8 inch holes in the plexi , leaving
a sizable perimeter area for my template to maintain it's strength .
I can lay it down on ANY flat surface and spray paint over it to make an entire
Battletech board in one go .
The outside perimeter has been glued back together at least a half dozen times .
The part with the holes has remained perfect .
Plexiglass flexes until it just fails .
The failure lines are rather unpredictable ,and create sharp dangerous edges .
Light hits seemed to cause catastrophic damage while some hard impacts did nothing .
I think the holed section hasn't broken because the gaps have more give .
It seems to be more brittle then it originally was as well so I avoid transporting it
unless it's a necessity to complete a special project .
For the base of a modular terrain system-IMHO I would recommend another medium .
If you're dead set on avoiding a roll out matt- then perhaps you should go back to
a hardware store and check out the various building materials available .
Styrofoam insulation and hardboard come to mind for starters .
