Steep parallax in UE3 / Brothers in Arms (UnrealEd)

Jonathan

Just looking at the UnrealEd version that comes with BiA:HH, and I see a steep parallax expression. I checked some of the parallax materials in the game, and I haven't seen any yet that use it, so does any know how you would hook it up in the editor? Nevermind the textures, they were just quickly created this morning before heading to work. (the vector 3 input was just a quick color test, BTW)


Info on steep parallax mapping,

I'm assuming it works, and is for steep parallax, which would be cool.

Thanks for your time.

Nice info, thanks for the links. Any other games using this? BIAHH was the first? Seems like something that should have been in previous Unreal releases...

Not that I can give you an answer to your problem (apologies), but I personally never knew there was an editor for BIA:HH. Might have to check it out at some point.

No kidding?

Might have to get that game now just for that hehe

The Bia Engine was a modified version of Unreal Engine 3.
Benny Wilson created the steep parallax for use in Bia. The steep parallax can get very expensive and was used mostly for small things like bullet decals.

1-Create a new Mask node
2-Click on mask node and add a mask texture. Try a simple hole to start from black to white
3-Plug the Steep Parallax into the mask
4-Plug the mask into your bump and color
You should see immediate results in your preview window. Let me know if this works or not. -S

Thank you for the information. I'll try it this evening and hopefully have something to report back a little later. Thanks again.
