UDK material question

GavinUnit

If I need to connect both a TexCoord and a BumpOffset into the UVs of a TextureSample, how would I go about doing so? I figured I could just Add both of them together then run them in, but that didn't work out (I'm still learning UDK, haha).

Sorry for asking such a stupid question, but I've tried searching this up and simply CANNOT find an answer. I seem to waste majority of my days just searching for answers.

Thanks for any help

I haven't been using UDK very long, but maybe try using Append or Add to combine the two into one.

The Tex Coord goes into the Bump Offset which goes into the Texture UV's slot.



Plug a texcoord into the coordinate slot. You can also have more than one Texcoord nodes. The materials compendium page on UDN is great to reference for materials and shaders.

Isnt there a UV coordinate node-in on the bump offset? In which case you just plug in the texcoord into bumpb offset then into the sample.
Edit: wow, minute instant grill

Add works in the sense that it puts the two functions together, but it doesn't apply the TexCoord (tiling texture repetition) to the BumpOffset.
So I get the texture tiling like I need it to, and I get the bump offset affect I need, but I need the BumpOffset to apply the TexCoord values to itself aswell.

Thanks for the quick reply

Ah, a bunch more replies, yay!
I'll take a picture to show you guys my situation.

It's these little things that are hard to solve when your learning a new program - too tricky to google for! If you're having the same stumbling block I had working out bump offset, then I think you want something like this?

Quick hands Fearian has what I was talking about.

Sorry If I'm not explaining very clear. I was following a water tutorial and thats what all the panners and things are from.

**Edit
That MaterialComp you sent is aaaawesome, thanks Salami! I've read thru a few things like that but this one is really detailed.
I really appreciate the discussion going here, thanks for that

can we see more of the tree? you have to plug it in back at the start I think if you want it to affect the output.

This doesn't directly answer your question, but this tutorial goes over alot of useful material set ups and shows what I mean about keeping the texture coordinates at the back and pluging it in where its needed.

Alright, I've added a few tiny things since the last pic, so it's slightly different, not that that really matters.
I updated the picture up there, in the meantime ill check out those yummy videos. Thanks

***Edit
I ended up just going into all of my TextCoord's at the beginning of the chains and scaling those accordingly. Worked just fine that way haha.

Glad to see it worked out. I had a giant headache after posting (probably due to playing half life 2) and couldnt stand looking at UDK :P
