Hey everyone! Today, I'm excited to walk you through how to create a cool iridescent material effect in Marmoset Toolbag 4. If you're into rendering and want to add that magical pearlescent touch to your 3D models, you're in the right place. Let's dive in!
Before we jump into the technical stuff, let's talk a bit about what iridescence actually is. You know that mesmerizing, shifting rainbow effect you see on things like beetle shells, soap bubbles, or oil slicks? That’s iridescence! It's caused by thin layers on a material that interfere with light, causing it to reflect and bounce multiple times within these layers. This interaction gives off those beautiful, changing colors depending on the angle you're viewing from.
In this tutorial I used a crab model to showcase how to achieve this effect. I think is a nice asset because the subtle iridescence really makes the details pop without overwhelming the overall look of the model. To get started, we need to assign a new material to our model in Marmoset Toolbag 4.
Once we have our model set up, the magic begins. Here’s a step-by-step breakdown on how I did it:
At around the five-minute mark of the tutorial, I touched on something super important which is lighting. If you've ever worked with metallic or reflective materials, you know that lighting can make or break your render. The way light hits your model significantly influences how the volumes are read, especially with an effect like iridescence.
To really bring out the best in the iridescent material, you can follow these few tips by turning on a few strategic lights in the scene. You can also experiment with their colors to enhance contrast and make the iridescence pop even more. It’s amazing how a simple change in lighting can completely transform the look of the material, making it more dynamic and visually appealing.
So, to recap, here’s what we’ve covered:
And there you have it! Creating an iridescent material in Marmoset Toolbag 4 is easier than it looks, and with these tips, you can add a magical touch to your 3D models that’s sure to impress. Whether you're working on a game asset, a concept piece, or just experimenting with new materials, this technique is definitely worth trying out. Happy rendering!
Now, we're diving into a super cool technique to create an iridescent material in Blender. If you've ever wanted to add that magical, color-shifting effect to your models using Blender, you’re in the right place!
Before we dive into the material settings, let's make sure our scene is ready to go. In the video, I used a simple setup that includes a plane, a few lights, and a crab model. You can use any model you like—just make sure you have some lights in the scene to really bring out the iridescent effect.
Now, onto the fun part—creating the iridescent material! Here’s how to do it:
With the basic setup in place, it's time to refine the effect:
Lighting plays a huge role, Here’s a quick tip:
And that’s it! You’ve now got a beautiful, iridescent material that is easy to tweak you can save it for later projects too!
In this part, we’re diving into a cool technique for creating iridescent materials in ZBrush. If you’ve ever wanted to give your models that shiny, color-shifting effect, this guide will show you how to do it using MatCaps. Let’s get started!
First things first, let’s talk about MatCaps. If you’re not familiar, MatCaps are materials in ZBrush that capture both the material and lighting in one image.
To start, we’ll use a test image with a gradient that transitions from blue to magenta. This gradient is key to creating the iridescent effect. You’ll import this test image into your MatCap settings, replacing the default image. This immediately applies the color-shifting effect, which you’ll notice is more pronounced on the edges or glazing angles of your model.
Now that we’ve got the basic effect in place, it’s time to fine-tune it. In ZBrush, you can adjust the Intensity A and Intensity B sliders in your MatCap settings to control how strong the iridescent effect appears.
By tweaking the Cavity Detection settings, you can control how much of the iridescent effect shows up in the crevices versus the smooth areas of your model. This is great for adding depth and realism to your material.
Next, let’s play around with the colors. In the MatCap settings, you have Color A and Color B options that let you change the hues involved in the iridescent effect. For example, you might start with a green and shift to blue or yellow, depending on the look you’re going for.
I also suggest using the Saturation A and Saturation B sliders to enhance the colors. Increasing saturation can make the colors more vibrant, while adjusting the hues can give you different material variations. Don’t be afraid to experiment here—this is where you can really make the material your own.
If you want to go a step further, I’ll show you how to inflate or pinch the image to bring colors closer to the center, creating unique metal-like materials. This is an optional step, but it’s a fun way to add even more variety to your iridescent materials.
Finally, I’ll share specific color values that work well for creating an iridescent effect. For example, I used a green base color with RGB values. These values are a great starting point if you’re looking to recreate the effect exactly as shown in the tutorial.
Happy ZBrushing, and don’t forget to check out the resources for this video, including the test image and some of my materials too ;)
