Trying to get height map working

Is there like a restriction for how big a heightmap can be? I'm trying to convert a map with the map converter, but somehow no matter how much I put at max height the map remains really flat, except for two mountains that are moderately high. Anyone here know how that works/why that is/made maps before?

Any input appreciated.

Also there is limitatation(sorta) because there is only 255 values so if you make map really high even 1 value diference is very clearly vissible and looks very ugly. By the way when you defining height in smd you dont even need to recompile map. Read .smd description in link or something. PS i have made only 1 map(WWF_RAW) so I m not pro.

Height values has limitations in theory, but basically you can go very wild with it (I think, though never tested the limits.) It's all about how many grayscale levels you use and how you set your levels in relation with each other through smf height values. For 8-bit grayscale its 255 levels. However, spring map format supports 16-bit grayscale images so it means 65,535 levels. This is what you should always use. 8-bit heightmaps looks ugly and limits the height variations. Usually 8-bit maps end up being jagged.

Height values are always written and hardcoded in .smf but you can override them via .smd. It makes the whole process a lot easier as wolas said: you dont need to recompile just to change heightvalues.

If your problems with flatness still exist please post a screenshot from ingame, heightmap and height values (both).

The texture seems to be broken or something, anyone any idea what might be causing it?
