The color is changed dark. And Specular Reflection is not working, I can't control that. Attachments: Up to 5 attachments including images can be used with a maximum of 2. There is not normal map in my program. But I already tested two case, it's not working. Then I download Arnold render from this site, there is normal map.

Creating and Using Normal Bump Maps

To try Arnold please visit the Arnold Trial page. Fix Dark shadows and Rainbow Normal Map? Why do my normal maps appear to be inverted? Find posts, topics, and users Ask a question. Home MAXtoA. First at all, sorry for my bad ENG. I'm using 3ds MAX This is basic setting. They are look like almost same. But I add normal map, it didn't works well. I try change gamma 1, 2. Also It's not X Y Z direction problem. Every normal map make same result.

This is same setup but ART render. It looks like right result. How I fix that normal map problem?You can use a bitmap file or procedural map as a Bump map, which makes an object appear to have a bumpy or irregular surface. When you render an object with a bump-mapped material, lighter whiter areas of the map appear to be raised, and darker blacker areas appear to be low. A Bump map uses the intensity of the map image to affect the surface of the material.

In this case, the intensity affects the apparent bumpiness of the surface: White areas protrude, and black areas recede. Use a Bump map to take the smoothness off a surface or to create an embossed look.

Keep in mind, however, that the depth effect of a Bump map is limited. If you want extreme depth in a surface, use modeling techniques instead.

For example, the Displace modifier pushes surfaces or faces in and out based on the intensity of a map image. Using a Displacement map is another way to emboss a surface. Grayscale images can make effective Bump maps. Maps that shade between white and black generally work better than maps with hard edges between the white and black areas. The Bump map Amount setting adjusts the degree of bumpiness.

Higher values render as higher relief; low values render as low relief. The bumpiness is a simulation created by perturbing face normals before the object is rendered. Because of this, bumps don't appear on the silhouette of bump-mapped objects. To assign a Bump map:. If you choose Bitmap as the map type, 3ds Max opens a file dialog that lets you choose the image file.

Alternatively, you can use the Slate Material Editor to wire a map node to the Bump component. Note: The effect of a Bump map is not previewed in viewports. You must render the scene to see the bump effect. Tip: To avoid aliasing caused by a 2D bump map, go to the bump map's Coordinates rollout. Set Blur to be in the range 0. The default Blur and Blur Offset values work well for mapping other material components, but for bump mapping, lower Blur and higher Blur Offset values give better results.

Tip: When using a Standard or Raytrace material, if you notice aliasing in the bump highlights, try turning on supersampling and rendering again. Note: Most controls on the Output rollout don't affect bump maps. Only the Invert toggle is considered: It reverses the direction of the bumps. Procedures To assign a Bump map: Click the map button labeled Bump.

Choose from the list of map typesand then click OK. Use the map controls to set up the map.The low-resolution model should have the general shape and outlines of the high-resolution model, and typically it should be a bit smaller, so that projected detail in the high-res model will appear to be above its surface. The Render To Texture dialog appears.

As for other kinds of texture baking, it creates a Shell material and applies that to the low-res object, with the Normals map assigned as the bump component. Create a simpler, low-resolution model. Select the low-res model. Choose Rendering Render to Texture. Choose the high-res object, and then click Add. In the Projection Mapping group, turn on Enable. Note: At this stage, often you will click Options to display the Projection Options dialog, which has a variety of settings for how to generate the projection.

Topics in this section About Normal Bump Maps Normal bump mapping is a way of adding high-resolution detail to low-polygon objects.

It is especially useful for real-time display devices such as game engines, and it can also be used in rendered scenes and animations. Troubleshooting Normal Bump Maps Because of the variety of geometry and different situations that can arise, normal bump maps sometimes give unexpected results.

Usually there is a workaround for the problem, or more than one. This topic describes some situations that can arise, and ways to correct them. Related Reference Projection Modifier.A Displacement map displaces the geometry of surfaces. The effect is similar to using the Displace modifier. Unlike Bump mapsa Displacement map actually changes the geometry of the surface or patch tessellation. Displacement maps apply the gray scale of the map to generate the displacement. Lighter colors in the 2D image push outward more strongly than darker colors, resulting in a 3D displacement of the geometry.

The Displacement Amount value is measured as a percentage of the diagonal of the bounding box for the object that contains the patch or surface. This makes the displacement effect consistent for all surfaces in an object, and it also means that when you scale the object, the displacement is scaled with it.

You can apply a Displacement map directly to the following kinds of objects:. With other kinds of geometry such as primitives, extended primitives, compound objects, and so on, direct use of a Displacement map is unsupported. Disp Approx works with any kind of object that you can convert to an editable mesh.

The effect of a Displacement map isn't visible in viewports unless you use a modifier:. Under certain circumstances, such as when the underlying mesh is fairly simple, using a Displacement map on an editable mesh can cause problems because of the way the underlying mesh is tessellated.

When this happens, smoothing does not work properly and you can see the underlying wireframe mesh in the surface itself. To correct this problem, use these techniques:. If you choose Bitmap as the map type, 3ds Max opens a file dialog that lets you choose the image file. To apply a Displacement map to other kinds of objects:. You can adjust the Disp Approx modifiers parameters, or you can leave them at their default settings.

Warning: A Displacement map can generate many triangular faces per surface, sometimes over one million faces per surface. While using a Displacement map can produce impressive results, it can cost a lot in terms of computation time and memory. Note: If you apply a UVW Map modifier to the surface, all maps obtain their coordinates from the modifier except for the Displacement map, which always obtains its coordinates from the original surface or the Disp Approx modifier.

Choose from the list of map types, and then click OK. Use the map controls to set up the map. To apply a Displacement map to other kinds of objects: Select the object. Go to the Modify panel and choose Disp Approx from the Modifier drop-down list.

Open the Material Editor.

Thread: Normal Maps with vray in 3ds Max? Add Thread to del. January 30th, 1. Bradley DeWald. Normal Maps with vray in 3ds Max? I can't seem to get normal maps to work with Vray in 3ds Max. Can somebody point me in the right direction? Share Share this post on Digg Del. January 30th, 2. Scott Schroeder. Re: Normal Maps with vray in 3ds Max? If I remember correctly the method the normal map is displayed in plays into how your normal map is shown, at least for the standard normal bump map.

If I can push past the fuzz in my head, I think either world or screen will give you better results than the default tangent. The Vray normal map doesn't use this so I'd say use the Vray one since it's simplified. Does your normal map have the height map in the alpha channel? In many game engines, normal maps like to have the height map in the alpha or referred from a height map file so it knows how far to push the normals. January 30th, 3.

It doesn't look like it has an alpha channel. I'll give the VrayNormalMap another spin. Thanks for the help.This map is typically assigned to the Bump or Displacement component of a material, or both at once.

Bump And Displacement Map: Overview

Using the map for Displacement can correct edges that look too smooth, however extra faces are added to the geometry. For more information on Normals maps, see Baked Texture Elements.

When you manually save a file to be used as a Normal Bump map, be sure to choose Gamma Override, and set the Override value to 1. Normal Bump maps save calculated values that are precise, and visual correction is not needed.

Use the spinner to increase or decrease the map's effect. By default, the Normals map's red channel indicates left larger values versus right smaller valueswhile green indicates down larger values versus up smaller valuesand blue indicates vertical distance. The controls in this group let you adjust that interpretation. The Method group lets you choose which coordinate to use on the normals.

These controls are the same as those in the Projection Options dialog. This is the method to use for objects that both move and deform, such as animated characters.

This method can be used for stationary or moving objects, but not for objects that deform: If the object deforms, the projection will appear incorrect at some frames.

This method is useful mainly for stationary objects seen only from a single angle; for example, a statue seen through a window. Applies a texture-baked Normals map to a material. Additional Bump This optional component can contain an additional map to modify the bump or displacement effect. It is treated as a regular Bump map. Channel Direction group By default, the Normals map's red channel indicates left larger values versus right smaller valueswhile green indicates down larger values versus up smaller valuesand blue indicates vertical distance.

Tip: If you notice artifacts in Nitrous viewports when you use a Normal Bump map generated by another application, try changing the Normal Bump option on the Preferences dialog General panel.

Note: Autodesk 3ds Max corrected a Normal Bump map issue that appeared in versions prior toin which 3ds Max used a different tangent basis generation method than other rendering systems.

There was no way to change this method. As of version3ds Max provides three modes, each compatible with a particular method: 3ds Max, Maya, and DirectX.

See Normal Bump Mode group. Method group The Method group lets you choose which coordinate to use on the normals. Tangent The default. Project at a tangent to the target object's surface. Local XYZ Project using the object's local coordinates. Screen Project using screen coordinates; that is, flat projection in the Z axis.

X is horizontal, increasing in a positive direction to the right; Y is vertical,increasing in a positive direction upward; and Z is perpendicular to the screen, increasing in a positive direction toward the viewer. World Project using world coordinates. Parent topic: 2D Maps.In the example shown here, a metal normal map is used in the normal channel and separate plank texture is used for the bump channel.

Care needs to be taken for correct gamma correction of any bitmap textures assigned here. Some software packages generate normal maps that include a 2. The mapping channel that defines that UV space can be specified with the map channel parameter. V-Ray assumes that the blue B component is "up" for the normal map the direction along the surface normalwhich means that the "neutral" color of a normal map is RGB, This can be swapped with the green G channel using the swap red and green parameter.

This is needed for maps produced by some software packages. Some software packages assume that the green G component of the normal map is the "up" direction along the surface normal.
