Description

In this collection of MARI tutorials, we will be taking a detailed look at each of the filters available to us in MARI. Each tutorial in this course is a self-contained lesson centered on one of the filters available in MARI. This means that these lessons can be viewed in any order you wish, allowing pick and choose content that is relative to you. Over the course of these lessons, we'll discuss not only how each filter works but also the best way to apply it in order to obtain optimal results. Software required: MARI 1.4v2.

Introduction and Project Overview
[Autogenerated] in this lesson, we'll learn a variety of techniques for applying Murray's filters to various areas of our project will also be learning about how we can begin masking those filters. All right, so I have are 7 89 c truck asset open in front of me here. Now the first thing I'm gonna do before we get into the filters is I want to choose a nice color. Let's just choose. Maybe I don't know a green color here, and I'm just gonna paint that right and it's on the side of our truck here, just like, so great. So now, with that done, just know that there are a variety of different areas here within our project that we can target with Murray's filters. So let's open up a filter here. Doesn't really matter which one. I'll just choose brightness and let's go ahead and skip all these options and jump down to the bottom. Now we do have several lessons in our library covering each one of Maurice filters. If you want to look at these filters and mawr in depth detail, feel free to check those out. I'm gonna go ahead and drop this down and noticed that we have two settings right now for areas we can apply this filter to. We can apply it to the current painting or the current channel. Let's look at both of those. I'll just apply it to the current painting first. Here, make some changes and you can see that the changes I'm making are being applied to the information in our paint buffer, that green spot we just painted. Now, if I go ahead and change this to current channel, note that the current channel I've selected is my diffused channel. That makes some changes at this point, and we're making changes to all of the pixel data that lives on that particular channel. You can see everything, but our paint buffer is being changed now. There's a little different iteration on this current channel setting. Let me go and cancel this out, and I'm gonna go ahead and use my selection tool to select the patch that has our tires on it. Here. You'll need to be in patch mode to do that, but it's going to do that and access that same filter here at this point. Noticed there is 1/3 option available to us, we can apply our filter to the selected patches on Lee of the current channel. So if we select that, you can see here that my changes air on Lee being applied to that patch that has the tire on it I selected. Now let's cancel this out and look at one other way that we can apply. Maury's filters wouldn't clear my paint buffer out, and at this point, I want to jump over to my image manager. Now, I have some images in here already, but you can find these images in your images folder within your project files. Go ahead and select. One of these images may be this rust colored image here, and I'll actually double click on that just to open up the image just so you can see the changes. We're making a little bit easier. Let's go ahead and access or Brighton's filter again here. Now, at this point, if we look in the drop down for apply to, we'll find 1/4 option available to us. This one is for selected images, so at this point, we're not gonna be applying this filter anywhere on our canvas. It's only gonna be applied to this image we have open. So let me just make some changes to that here. There's blow that one out really bad just to make a nice contrast ing image, and it's quite apply that notice what happens over here in our image manager. We didn't overwrite the Thean Mages to that we started with. Rather, we made a copy of it here with those changes applied. So we're not gonna worry about damaging those original Image is good and close that out. And I tell you what. Let's do. Let's go ahead and d select any geometry we have here and let's go ahead and paint some information back into our buffer. I'll go and choose a right green this time. Paint that in on the side of our truck, just like so, and let's begin to talk a little bit about how we can mask thes filters out. So this'll first method is really only gonna be available. If you're wanting to mask out data that's in your paint buffer. We can do that using Maury's Marquis selection tool here. So let's just say that we've painted a lot of things green here, but we There's something here in the middle that we don't want to paint green. I'll use my lasso and we'll just make a selection here. We'll just draw sort of a shape. Maybe like that. Maybe we've drawn a lasso around the object that we don't want to actually make green. And let's say that this point we want to make changes to everything that's not massed out here. Well, let's go and bring upon a filter to do that. So well, just choose. Maybe the hue filter this time and we'll go ahead and switches over to the current painting. And now the mask information below. This is what we're gonna pay attention to. Now, if we drop that down, you're gonna notice that we have a marquee selection option. But we also have options for all of the images in our image manager. We'll come back to those here in just a moment. But let's go and choose the Marquis selection option, and we'll make a change here before I do that. Let me just so like none and I'll make that change and you can see that that changes being made on into the area we have selected But if we decided well, we wanted to use this selection is a mask notice it's back to the original green color. So what we're going to do is by hitting apply on this. And if I d select that information now, you'll see that we on Lee made changes with that filter to the area that wasn't selected here, So the selected area was protected. Great. So there are a couple of other ways that we can actually mask out Murray's filters. So we just clear that paint buffer out one more time here and let's go ahead. We're gonna jump over to our default shader here, and I want to show you that this bump channel right here contains simply scaler, bump information, black and white information here. So let's go ahead and jump back over here to our diffuse and I'm going to. But I showed you that because we can actually use a channel to mask out of filtering effect as well. So let me go ahead and again bring up the Maybe the brightness filter will apply this to the current channel and for mask, let's go ahead and jumped down here and choose our bump channel noticed that we can select current channel bump and diffuse, but we can't selecting the images or the, uh, marquis selection. So and there we go. We've got our bump channel selected, and now we've got some new options available to us here. I tell you what, Let's go ahead and just bring the brightness up here, and we'll just kind of take a look at how that is affected with the default settings here. Now, what we've got here is an invert check box. We can invert that channel and how it's being used it to mask out our information. And we also have a masking curve down here that little our button resets the curve. But essentially, this curve controls how the mask is being applied. So black being over here on the left, white being over here on the right. I'm familiar with masking. You know that black is gonna hide it. White is going to reveal it so we could come in here and begin dragging these little green circles around to kind of adjust the way that particular mask is masking out that filtering effects so we can drag these around, reposition them if we want to. We can also add additional control points to the curve here. Just simply like clicking on the white line. That way we have a lot more control over the curve itself. We can remove those control points by control clicking just like so we can't remove below four points. So we have to have, at least for these. But I didn't reset that here. Okay, so let me go and cancel this out. We'll show you one other method of masking out Are filtering effects here. Now, notice. When we looked at that channel masking, we didn't have the option to masked by an image. But rather when we just paint in that bright green color again here and we'll apply a an effect here, let's go ahead and maybe just choose the que effect again. When we're working with applying this to the current painting, we can select either the Marquis selection as a mask or one of the images from our image manager here. So feel free to experiment with this and select any of these images that we've got over here. Let's just maybe select. Select that rust image first, and you could see, my dialogue has gotten rather large, but we again have that invert option and control over the curve. Let me go to make a change here. I'll go ahead and make a change to the Hugh here. And you can see exactly how that image is being used to mask out this filtering effect right now, There we go. Maybe change the value of that a little bit. And again, if we want even more control over how that mask is applied, we could come down here and begin to play with the control points here on our mass curve. All right, Great. So then is a look at the various ways that we can apply filters here inside of Mori as well as mask those filters.
