Hello, i would like to make a request on a Tunnel Sign. And if you want to, maybe some more danish signs?

https://en.wikipedia.org/wiki/Road_signs_in_Denmark

I'll add the tunnel sign thanks for the suggestion, and about the danish signs: I thought about creating resource packs for different countries. You can do that yourself though, I'll make a template where you can just put in your files with the correct name. I'll make a tutorial on my website and give you the link when I'm done.

I hope this covers everything: https://derfl007.000webhostapp.com/tutorial/custom-road-sign-textures/

That's some good ideas thanks very much

I am gonna take a look at it.
I got some more ideas/improvements:
Diagonal Fence?
Sign with lamps pointing from bottom and up on the sign?
Some road construction signs/fence? Maybe concrete barrier?

Is it possible to add either road textures, or new things on the road blocks, like shark teeth using resources packs?

Oh, and if i follow the tutorial for the the resourcepack, will it override the ones there already are in the mod?

You can of course change any resources you want, adding new stuff would require changes in the code.
And yes mod textures should override by resource packs

So if you wanted for example yellow street markings, you just need to change the textures and put them in the resource pack

But i would not be able to have both white and yellow on the same time?

Unfortunately no
