A while back I posted an issue on github about 2048+ size heightmaps, soon I discovered that the problem with that size could be with the vram memory, but the thing is that in cryengine and UE4 I can import 4096+ heightmaps without any problems. Loos like this is a T3d problem after all. https://github.com/GarageGames/Torque3D/issues/411 My specs: Inter Core 2 Duo 1.8ghz 4 gb ram Radeon HD 6950 1 gb ram
