Problems with Remere's Map Editor --------------------------------- So for ease of research, I will put some common RME errors and their solution in this topic along with a simple mapping introduction tutorial, to make searching and solutions easy, all together in one topic. **troubleshooting:** Could not locate tibia.dat and / or tibia.spr, please navigate to your tibia insalation folder. - To solve this problem, open your RME, go to preferences and uncheck the "Check file singatures" box. If the error continues, download the tibia version corresponding to your map (if you want to open a 8.6 server, download tibia 8.6) copy and paste tibia.dat and tibia.spr to your RME destination. Invalid Items (gets one red floor, or certain item sprite from another) - To solve the problem, copy items.otb from your server (data / items) and paste it into the RME folder that contains your server version. If you can't find the RME folder, open execute (windows + r) and type% appdata% and enter. Lag in the RME - Often inevitable and caused by the machine itself. Something that may help is to "clear" the screen, so in the "view" tab uncheck things like: Ghost higer floor Show shades Show Spawns (if necessary turn it on and off) Gird show or any other show that may be disabled at the time of editing. Rme stop working - The rme stop working out of nowhere can be caused by several things so i will cite solutions by topic. Disable your anti-virus. Upgrade Your Visual Studio and DirectX Search for invalid items on map and remove them See if you are using a compatible version.
