There always be modding. With or without official support or whatsoever. The only difference is that with official support it will better for everyone.
For personal, offline use I think we can use (and make videos with it) any model (mesh) we find on the internet, including from another games, but with the current polygon limits is close to impossible to recreate a detailed model, so please think about this.
Well, I can find or buy this model from another place - in that case? Or I should recreate it by pictures from scratch? I mean how someone would know if the model is ripped from Forza or made from scratch if not told so? I think this is more Mazda's copyright infringement than Forza's.
1. Collision box problem - what if the mods have a different types of collision box models - someone makes a mod -> this mod first must be approved by the moderators -> send to the developers to add the new collision box model -> add it to the game.
2. Copyrights infringement - what if the real car models have a different name, no emblems, no badges (like in some low budget movies or tv series) so there is no advertising - example - CarX Drift Racing (we all know the car brand):
Even if it is non-profitable for educational purposes, offline only?
I'm talking about an offline use only. But anyway what if we can change the collision box - so the mods can fit the exactly ... but that can happen only with official mod support.
What if I change the name of the car, remove all of the logos, badges etc. so only the base shape is the same? I'm not a very familiar with the copyright infringements, but something that Chinese car manufacturers do - copy the base shape and change some minor details.
This. Please, LFS needs that. (The both solutions will be better than how it is now.) ^^
EDIT: Don't know if this is the right moment, but i've been thinking about adding a subtle motion blur effect. It would be amazing for the video makers. It can only be in replay mode (like Gran Turismo Sport).
