so a long time ago, roughly 2013 so... roughly 7 years ago i used to make alot of maps, i've looked through the fourms and currently all of the mods and such are off (T_T) so i've tried changing rendering system, changing graphics checked that if it all correct, even changing the coding for the map, here is where it gets weird, ive checked, my map is in greyscale, has no alpha layer, is 513X513 a png ect, i think it may be my pc since its kinda old, but its only feral heart that crashes, so here is what happens i open map maker with my height map (i've made several and none of them work) and everything is fine, can do whatever i want, until i add in the terrain map, then it crashes and gives me the "feralheart has stopped working" popup, then forcefully closes it, now heres a step further, my map is exported, so when i go into the cape of distant worlds i can see my terrain map, but the overall terrain is flat, i have a picture, but unfortunately i am not sure how to attach a picture, i was never really on the fourms T_T, every other topic of this that i've found has been solved, and i have tried the methods there, and the tutorials but nothing seems to work, can someone help me with the pictures then check if it is just my pc chugging, or what.
also sorry if this is wrong topic or there was a preexisting thread that did have my problem that i did not find, thank you for taking the time to read and assist.
