Solution found for you JC Leon:
Found the issue with the one you sent. Unmodified, it causes the LM to crash. I opened the fpe file and commented out the effect line like so.
;header
desc = gv_obj_oldcity_03
;visualinfo
textured =
;effect = effectbank\reloaded\entity_basic.fx <------ **** rem this line or remove the shader effect call
castshadow = 0
Kept the rest of the FPE file the same. deleted the dbo and bin file for that object and tried again.
Setting it in the editor, running test game, and using F4 Lightmapping, and it finished fine.
The error refers to the assigned shader, not being able to find the listed texture. This would be true as you are using multitextured models, and would not have the texture listed in the FPE file for the lightmapper to find.
Hope that solves the rest of them.
Thanks
