All my answers are based on previous versions (most specifically FH3, but they should apply to 4 since they’ve been pretty consistent over the years
edit- just tarted reading about influence, didn’t know about that until now- sorry I can’t answer how the rewards will work that way
Is the ability to share paint jobs available in FH4 and do you get influence for others using them?
not sure about influence, you got in-game currency in previous games
Do you have any idea how much influence you typically get from this activity?
100 credits per sale, 500 per ‘like’, 200 per use (based on FH3)
Are primitive shapes and decals unlocked or are they all available from day 1?
Everything is available right off the bat. There are several pages of primitives and 11 different fonts. Here’s a place that some painters hope things change every game, but so far nope
Is it possible to share just the decals I have created?
Yes. The pay is the same as liveries
Can you ‘follow’ or subscribe to a particular player to see what paint jobs they have available?
Yes .
Do paint jobs have a time limit for how long they are shared before needing to be re-posted?
No, they stay shared once they’re posted. It seems to me there’s been a glitch or two where things got knocked down, but it isn’t very often.
Is there a limit on the number of paint jobs you can share and if so, can you increase that cap?
Yes, there’s a limit to how many you can share (I think it’s 300 in FH3, which is also the limit to the total number that you can have in your game period. Which is ridiculous because you can have over twice as many cars, so not even being able to have one on each car is kind of dumb. Also something we hope changes in each new game. Let’s keep our fingers crossed lol). edit- and no, you can’t increase it.
Can you browse through a player’s collection of paint jobs or are you limited to just seeing what is available for a car you own?
Each player has a ‘storefront’ in FH3, and I think you can browse other players’ storefronts, but I’m not 100% sure on that.
Is there a system whereby you can to an up-vote or like for a paint job even though you aren’t currently using it?
I think you can like them after you download them without actually having it in use, not 100% sure on that one either.
Are the devs planning on having featured paint jobs of the month based upon the number of people using them?
There are usually top-rated designs when you go into the paint section for specific cars. Plus, in the past they had contests where the winners would get top spots.
Can you privately share a paint job with another player? (ie. they’ve asked for a one-of-a-kind commissioned design)
Not really. I think the closest you can get is to share it then remove it after they get it.
Are there any copyright restrictions for what you make or is it all considered ‘fair use’?
Not copyright restrictions per se (since you can’t import anything and have to make them from the primitives) but they will drop the ban hammer for anything someone finds offensive (and I mean anything). Then you can get banned for a month first time and much longer (up to permanently) for future transgressions.
Can you update or edit shared paint jobs or do you need to recreate it again if you want to make changes once it is published?
You can update them, but when you re-share it the counts start over I believe.
Again, this is mostly based on previous experience, not knowledge about FH4 in particular. Most I’'m sure will stay consistent based on experience with previous titles.
