Thank you for your answers.
I know it is possible to change from one age SDL and hide the objects of this age with Python. This is what I do for a long time.
Import PRP in another age, I do that too and even clone objects.
For the FMT I realized Treasure Light City (TLCity) that way. But to implement all these changes, it takes a relatively long time. Furthermore, as is my robot that performs these operations, it must remove the objects every time a new player arrives at this age. All this slows down the game for both players and the bot.
That is why I intend to recreate TLCity by removing unnecessary objects Ae'gura and redesigning parts. For example, if I remove "Treebolisk" and its collision wall, then the player falls into the void. There are no ground collision around TreeBolisk. I Must redraw an invisible wall on the floor at that location.
I would afterwards, repair the pub of Kahlo and other locations (Tokotah Alley, for example). I know that will take a lot of time, but I have
Regarding the modified PRPs.
Indeed, I do not think Cyan agree to add a new age (TLCity) in Moul: a. But it would be possible, I think, to distribute it to players who use a Client Internal (Plclient). Or, why not consider putting all the FMT in a Shard that would agree to host it?
Anyway, I'm at the very beginning of my studies in modeling of an age with 3DSmax. I have successfully created a simple test with age 3DSmax 2012 and convert the PRP with Drizzle. My avatar can link it by the Nexus then with the command "/Link".
I will try the solution you suggest me: import in Blender, export, and import with 3DSmax. Edit, and then export the modified PRPs.
But I thought of something: Delete objects with PlasmaShop and save the modified Prps . This would be a lot of work done prior to import these PRPs in Blender and work on them. Currently, I'm using PlasmaShop 3.0 beta (build 167). In this regard, is there a most recent version of Plasmashop?
Thank you for your help.
