Welcome back. Once again everyone in this video Our goal is to create some materials who apply to our BP secret wall and BP secret platform whenever the user activates their Lens of Truth scale, here I am back in my older version of the project, let me just go ahead and activate my Lens of Truth ability. You'll notice that when I use it, our secret wall over here is going to turn the shade of C to purple. My sticker platform is the shade of C through yellow. Those are the materials that we're going to be working on creating. So let me just hop on out of here.

Reduce this version of the project. Here we are in our version of the project, and we're going to navigate down to our Metroidvania materials folder. And let's right click, create a brand new material from the right click menu and when Call this first one m underscore Lens of Truth underscore wall. And with that created, let's double click on it to open it up. This is going to be a relatively simple material. Now you can get pretty crazy creating all kinds of complex materials.

This one is going to be way, way, way simpler than that. Let's start off with this master material node selected. Over in the Details panel. We want to change our blend mode here from opaque to translucent, and when we do, it is going to make this opacity inputs suddenly activated, meaning we can plug something into it and so we can make this material see through. Okay, so with that done, we're going to add a few notes here. The first note I'm going to add is going to be known as a constant three node.

You can find that by either right clicking and look Looking for a constant constant three vector rather, that's one way to find it or if you hold down the three key and left click, you can get one that way as well. So with this selected, I'm going to come under the Details panel. And I'm going to set this to be a a b value of one. So I essentially want a blue color here and I'll leave R and G or RNG alone. Next, I'm going to add a Texture Sample mode we can get one of those by holding down the T key, t as in Tom left clicking there is a Texture Sample node. With that selected over in the Details panel, I am going to slot in our what was that clay old clay.

Brick clay old brick clay old, the diffuse version, not the not the normal matte version there the black brick clay old D that's the version. I'm looking for. What we're going to do is we're going to add these two together. So you can drag off of our output pin up here, type in and bring in add node. And then out of our Texture Sample, we're going to drag out of this topmost pin. And if I click right here shows that result kind of this purplish brick, if you will.

Next, I'm going to drag out of this and simply type in a multiply. And I'm going to multiply this with this selected by a constant b value that says b value right here, a value of two just to kind of punch this up a little bit so that when we now plug this into the emissive color, it's just gonna kind of pop out a little bit and to see the difference as to what that multiply node can do. You know, you can play around with this number set it to 20. You know, you see something more like that which is a little bit too strong. I think two is a pretty good value. And now it's still not see through it at all.

Yeah, so we needed to plug something into the opacity here. And if I hold down the one key and left click, you'll bring in a constant, one node and I just did something, did something crazy here in our multiply node, let me just reset this. And let me go back to here. Okay, and what I just added down here was a constant one node. So if I right click, and type in constant is actually just known as a constant node, you can get it that way or by holding down the one key and left clicking. What this allows you to do is simply enter in a value over in the Details panel, and I'm going to set our value to be point 5.5 is going to be my opacity value.

So that means it is going to be 50% transparent. You can see kind of this image beyond now if I scroll around a little preview window here. That's looking pretty good. All right, let's go ahead and see That that's gonna do it for our secret wall there. Now for a secret platform, I could use this same material, although that is a little confusing, because we're going to be able to pass through our secret wall where we can land on that is collide with our secret platform. So I just want to give a little bit of a visual difference there.

So what I'm going to do is I'm going to come back to my content browser, right click on our m Lens of Truth. let's duplicate this and we'll call this Lens of Truth platform, not plat from platform. Let's double click on it to open this material up. And really, the only change that I care to make here is with the color here. So instead of this bluish color, I'm going to set the are the red to be one, the G two B one and our b value is going to be zero. That's gonna give us this yellow color.

And you can now see what this looks like. Let's go ahead and save that as well. And guys, that is going to do it all for this video we now have a couple of Lens of Truth materials that we are going to apply to our platform and our secret wall respectively when we activate our Lens of Truth, that'll do it all for this one guys. See you in the next one.
