Triplanar Mapping Deeply Explained (UE4, valid for UE5) 

Thank you So Much, your Comment makes the Video clear

Took me like 10mins to figure out, thanx mate!

Thanks, sure!

Oh well, I suppose you don't want to miss my next couple of videos then 😬

The first version (without the smooth transition between the different planes) it's quite a lot more performant, the second one is basically the same :)

Sorry about that, in my most recent videos I've been trying to zoom in more :D

I answered you in Discord :)

Bias 0.5, scale 2

I show that in the very last part of the video (7:06), but just with the Base Color. You have to do the same thing with all the other textures (pbr maps, normals) :)

@@VisualTechArt Thank you! I thought I had to sample/ blend them in a separate package 😅 I didn't realize it was all done in engine - thank you again 👍

@@VisualTechArt Wait, you didnt show how to get the stripped textures? Or do they look stripped because of the "X plane" code before the stripped texture asset? It's hard to read because not zoomed. Can you please paste the code at blueprintue? Ty

@@kenalpha3 What do you mean by "stripped texture"? :O

@@VisualTechArt sorry forgot the stamp 7:06. Two of the 3 texture sample [previews] look stripped because one is stretched wide, the other stretched tall. How do I make those 2 textures, to work in your code? Or what are the details of its stretch/scale value? I don't remember seeing you click on each one (scene cut) to see the Left panel details. Ty

I have to be honest here, I know the technique at a high level but I didn't take the time to study that deeply, even though few years ago we were testing some of its implementations at work (with poor results since the world of the game I was working on didn't have a landscape conformation that made that technique appreciable, so we dropped that). It consists essentially in a change of the texture tiling relative to the distance: if the surface is further than a certain threshold, scale up the texture. That's the basic idea behind that, but I don't remember/know all the other bits and bobs added on top of that. I'll redo some research on the topic, it could be an interesting video to do in the future :)

@@VisualTechArt It would indeed. Thanks

Of course, that's where it's actually used the most :)

Maybe this can help ;) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-13Br0xNZMBw.html

Do you mean the Marketplace level blockout thing? I don't have it but it looks like the materials are already world alligned.

@@VisualTechArt Thanks for getting back, yes that's the one. They are world aligned but they are not using triplanar mapping. If you rotate them, the materials rotate with the actor.

@@hakametal Sorry for the delay, I didn't see this comment :D It can be achieved by doing the very same thing I do here in Local Space, instead of World Space :)

If you're projecting on all 3 directions you shouldn't get any extreme stretch... Can you explain a bit more your issue? :)

@@VisualTechArt turns out removing the Constant Value Scale nodes completely has solved the stretched seams. I followed the tutorial to the end and did the 3 projections and everything. I assume your scale value was 0 then.

You have to correct the normal vectors :) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-13Br0xNZMBw.html

@@VisualTechArt thanks
