Types of maps

Diffuse Map

(Supported by quick shader and pixel shader)

• The most frequently used texture mapping method. It wraps the bitmap image onto the 3D geometry surface while displaying its original pixel color.

• Any bitmap image, such as scanned images or images captured by digital camera, can be used as diffuse map to represent photo realistic quality.

• Users can also use image software to make pre-rendered texture effects such as shadow, bevel, bump, lighting or weathering effects. this approach can adjust tively simulate real-world 3D effects while greatly saving system resources and rendering time.

Opacity Map

(Supported by quick shader and pixel shader)

• Make transparency and cut-out effects from grayscale images. the black part will get cut out; the white part will be fully displayed; the gray values determine the transparency (alpha) level of the object.

• Use bright gray # fdfdfd on the opacity map to make 2-sided 3D surface from plane mesh.

Bump Map

(Pixel shader only)

Bump mapping uses the grayscale values of an image map to create variations in the shading of the surface to which the map is applied. It adds details to 3D models without increasing the number of polygons. InIclone, White areas of a bump map are shown as high and black areas are shown as low.

By moving around the light source we can see how the angular light projection changes the bump look. if the light is facing the surface from a straight 90 degrees angle it the bump effects are the least noticeable.

Normal Map

(Pixel shader only)

• When you clickImport bumpButton you will find. Check this box if the map you are loading isNormal Map.

• ANormal Map(Pixel shader only) is made from a high polygon model. Its Color Representation will affect surfaces like a regular bump map while providing higher degrees of detail.

• IcloneCan import normal maps created in zbrush or 3D Studio MAX. By usingNormal mapsYou can make simple low-poly models appear as highly detailed 3D objects.

• If the image you are loading is not a specially designedNormal MapThe result will not be as good.

Specular map

(Pixel shader only)

This texture mapping method allows parts of an object to haveSpecularEffect.

Tip:
	Using the same image as bothSpecularAndOpacityMaps allows you to create Special Objects.

Glow Map

(Pixel shader only)

This texture mapping technique allows users to control the glow shape, color and strength.

• Glow maps will blend with your original Diffuse maps, so the lighter the diffuse color (or glow color), the stronger the glow effect.

• A bright diffuse map in combination with a bright glow map might cause overexposure.

Note:

Tips to create a subtle and valid tive glow effect: Choose a diffuse image which cocould ideally glow in the real world. Prepare the glow map, pattern and color design Start by testing from a darker glow map, then increase the brightness step by step to see the best brightness setting Decrease the overall ambient light

Reflection Map

(Pixel shader only)

Reflection map is also referred to as environment map. The image map is projected onto a 3D surface to represent a reflection of the environment.

TIPS: To create good reflective effects you shoshould start by using an object that has high specular highlight and gloss values. then apply black or darker images as the diffuse map to help making the surface work like a mirror which can fully reflect the reflective map content. if the diffuse map itself is too bright the front light plus reflective setting cocould cause the result to be overexposed. Most 3D blocks items are preset with a non-glossy material setting. To achieve high gloss and specular objects, check the \ props \ gloss folder Adjust the camera and light ction to see the natural changes to the reflective surface. If you place a reflective object on a simple 2D background you can use high contrast scenery images to mimic the reflective look by importing them as reflection map.
