I deleted etc in the first attempt with .upper, now with .lower the game takes into account the delay but the transition is not applied, just 1000 ms waiting and then the new scene appears.
The log say:
22:38:32.555:Failed to run string in Lua:
22:38:32.555:String content: --[VISMODULE,id,version,chksum]
then write all the shader script ..
and at the end of the shader script ..
22:38:35.689:'Load/Save autosave' action part of action 'At beginning of scene' (data id: 1508) was not executed because scene is currently faded.
I think the last string is related to the fact that it overlaps the starting autosave with the script.
I think I'll use the values, it looks better suited to a Lua noob like me
Thank you so much Lee for your effort, you're always kind.
P.S. Well I'd have another crazy idea, but it includes Lua too.
