Mega Shapes v2.38 (Latest version)
Mega Shapes v2.33
We’ve all seen games with beautiful rolling backgrounds – now you can have them too!
Making a racing game? No problem with Mega-Shapes. Draw a spline for the road, draw a cross section and then loft a road. Want more detail? Then loft a barrier and it will automatically conform to the road surface. Slide the barriers in or out, scale them, twist them – your imagination’s the only limit! Use the powerful rail clone feature to repeat and position sets of objects along your path, like fences, power-lines, trees, etc! You can even have your lofts conform to terrains or any mesh under them, and now you can carve your lofts directly into terrains to get a perfect blend from your loft creation to your game terrain.
MegaShapes also gives you a scatter system that will take any objects you choose and scatter them along your road and have them automatically conform to the existing mesh’s surface.
Other included systems are a complete Bezier spline creation system and convert those splines to meshes, dynamic hoses, tracked vehicle systems, basic rope and chain system, and path following.
