I was currently adapting the installer to Steam (detecting install path, adding a steam group icon, etc), then testing the mod on it. (thats also why for now i didn't posted the last mod release everywhere cause i thought there could be some issues so i just wanted to wait a bit to post something that actually works solid enough )
So, i think we are facing a first "issue" (nothing critical), i'm not 100% sure but i can't find the reason for now.
The bug i'm facing is, using the modded game on Steam, in 3D mode, several stadiums are textureless (not all, strangely, but lots of them). I double checked, the pk3's are exactly the same, not corrupted (the courta01.jpg our courtin's extensions in the paks are fine, not corrupted), and all works properly when running in a standard installation without steam.
-30 min later - :
i think i refined the issue a bit. The problem was not with custom additional stadium textures, but with the default ones (in_green, mid_synthetic, gs_clay etc), when i was using the no-ads patch, witch is restoring default game stadium textures on 3D courts, in the gamesys.ini.
Since a long time in ITST mod, i kept the default stadium textures folders, in_green, mid_synth, etc, present and replicated in the pak03.pak. Wich
shouldn't lead to issues anyway even if not necessary. Running TE non-steam versions shows no issue at all, but the behaviour seems different with the steam version, like it doesnt allow to replace default pak01 stadium textures folders in this environment in the mod pak03.
I made the simple test to delete these folders from the mod pak03, and then all worked flawlessly. Except one point : the only court i left unmodded from
vanilla TE, being Carpet, was leading to some missing data error #531, under steam again. In the mod i also replicated all the court01-court09 default folders,
to have basic reference court surfaces (modded physics), but kept the orginal carpet. So i just made the test, deleting the court05 folder, and then again,
it worked without any issues. (but here my physics modded court01-04 and 06-09, works flawlessly under steam, wich leaves me very dubious when seeing the
behaviiour with court05 and stadium files
So it's not critical at all, as i have a workaround here, but i think it was worth to report because the behaviour here is clearly different being in a non-steam or steam environment, so there is maybe something a bit fishy in there
