How can we tweak regular maps in Unreal Engine to attain extra hanging outcomes? Regular maps, a elementary aspect of 3D graphics, play a pivotal position in enhancing floor particulars. By manipulating regular maps, we are able to simulate intricate lighting results, including depth and realism to our digital environments. On this article, we’ll delve into the secrets and techniques of maximizing regular map power in Unreal, empowering you to create visually gorgeous scenes.
One essential facet of harnessing regular maps is knowing their impression on floor geometry. Regular maps encode the course of floor normals, which decide how mild interacts with the article. By rising the traditional map power, we amplify the floor particulars, making a extra pronounced phantasm of depth. Nevertheless, extreme regular map power can result in artifacts, similar to extreme bumpiness or distortion. Due to this fact, it’s important to strike a fragile steadiness to attain optimum outcomes.
Unreal Engine provides a number of approaches to reinforce regular map power. One efficient approach entails adjusting the fabric’s “Regular” property, situated within the Materials Editor. By rising the “Energy” parameter, we are able to immediately improve the affect of the traditional map on the floor geometry. Moreover, using the “Element Regular Map” function can additional improve floor particulars by introducing higher-resolution regular map data. Moreover, manipulating the fabric’s “Roughness” and “Metallic” properties can fine-tune the general look, creating supplies that reply realistically to mild circumstances.
Enhancing Regular Map Depth
Approach 1: Modify the Materials Regular Energy
Within the Materials Editor, find the “Regular” node and modify the “Energy” parameter. This immediately controls the depth of the traditional map impact. A better worth intensifies the traditional map, leading to extra pronounced floor element. Experiment with completely different values to attain the specified degree of element and depth.
Approach 2: Modify the Regular Map Texture
Open the traditional map texture in a picture enhancing software program like Photoshop. Modify the brightness and distinction of the feel to boost the depth of the floor particulars. Brightening the feel will amplify the traditional map impact, whereas darkening it’ll cut back it. Save the modified texture and reimport it into Unreal Engine.
Approach 3: Apply a Regular Map Depth Modifier
Create a brand new materials occasion primarily based on the unique materials. Within the Materials Editor, add a “Regular Map Depth” node. Modify the “Depth” parameter to manage the power of the traditional map impact. This gives finer management over the depth, permitting you to regulate it on a per-mesh foundation with out modifying the unique materials.

Leveraging Publish-Course of Results for Elevated Element
Publish-process results might be utilized to amplify regular map power, enhancing floor particulars with out modifying the traditional map itself. Unreal Engine gives an array of post-process settings that may be adjusted to attain this impact.
Ambient Occlusion
Ambient Occlusion (AO) simulates shadows in areas the place mild is blocked by close by objects, leading to elevated depth and realism. In Unreal Engine, AO is dealt with by way of the “Ambient Cubemap” setting, which might be manipulated to solid extra pronounced shadows, enhancing regular map particulars.
Display screen Area International Illumination (SSGI)
SSGI calculates oblique lighting in real-time, casting mushy, bounced mild inside scenes. This oblique illumination accentuates floor textures and regular map particulars, making them seem extra lifelike and immersive.
DOF and Movement Blur
Depth of Discipline (DOF) and Movement Blur may also contribute to elevated regular map power. By simulating digicam focus and movement blur, these results add depth and realism to scenes, and may improve the visibility of regular map particulars.
Desk: Publish-Course of Results and Their Affect on Regular Map Energy

Easy methods to Enhance Regular Map Energy in Unreal
Regular maps are used so as to add element to surfaces in 3D fashions with out rising the geometry rely. They do that by storing the course of the floor regular at every pixel, which might then be used to calculate the lighting and shading of the floor. The power of a standard map determines how a lot it impacts the floor regular, and might be adjusted to manage the quantity of element that’s added.
To extend the power of a standard map in Unreal, you might want to open the Materials Editor for the fabric that’s utilizing the traditional map. Within the Materials Editor, you’ll need to search out the traditional map node, which is usually referred to as “NormalMap” or “Regular”. Upon getting discovered the traditional map node, you’ll be able to improve its power by rising the worth of the “Energy” parameter.
The power of a standard map will also be affected by the roughness of the floor. Rougher surfaces may have a decrease regular map power, whereas smoother surfaces may have a better regular map power. You may modify the roughness of a floor by altering the worth of the “Roughness” parameter within the Materials Editor.
Folks Additionally Ask
How do I improve regular map power in Unreal 5?
The method is similar as in Unreal 4. Open the Materials Editor for the fabric that’s utilizing the traditional map, discover the traditional map node, and improve the worth of the “Energy” parameter.
What’s the distinction between a standard map and a displacement map?
A standard map shops the course of the floor regular at every pixel, whereas a displacement map shops the precise displacement of the floor at every pixel. Regular maps are used so as to add element to surfaces with out rising the geometry rely, whereas displacement maps are used to truly deform the floor.
Can I take advantage of a standard map to create a bump map?
Sure, you need to use a standard map to create a bump map. To do that, you’ll need to make use of a shader that converts the traditional map right into a bump map. There are a number of completely different shaders accessible that may do that, such because the “NormalMapToBumpMap” shader included with Unreal Engine.
