There's a table that's working for someone, in the thread under the Tables subforum. Crashes for me, but it uses the same method I used, before he beat me to posting. Find your weight's float value, right click -> what accesses... -> Should find an opcode with the following: adds xm..[rax+1C] -> change 1 to 0. It sets your weight to 0.
Thanks. I tried the debug function for fast travel. It shows 3d rendered "fast travel" and the character is moving without animation at a rather slow pace compared to horse riding. I wonder if it's possible to change the fast travel speed.
