Texture blending ​

DirectX example for Max 2026 and earlier

This example writes the result to a DirectX material with sgsdk_ConnectOutputToDirectXMaterial. Autodesk removed the DirectX material model from Max 2027, so the example is valid only in Max 2026 and earlier.

The following sections contain examples on how to blend textures using shading networks. It is recommended to read Shading network concepts before proceeding.

Texture blending using InterpolateNode ​

This script sets up two texture nodes that are blended using the InterpolateNode.

MaxScript

DirectXShader = sgsdk_CreateMaterialMetadata MaterialName

DiffuseTexture1 = sgsdk_CreateShadingTextureNode "DiffuseTexture1"
sgsdk_AddAttributeToNode DiffuseTexture "DiffuseTexture1mapChannel" 3

DiffuseTexture2 = sgsdk_CreateShadingTextureNode "DiffuseTexture2"
sgsdk_AddAttributeToNode DiffuseTexture "DiffuseTexture2mapChannel" 3

BlendColor = sgsdk_CreateShadingColorNode "BlendColor"
sgsdk_SetDefaultParameter BlendColor 0 0.5 0.5 0.5 1.0

InterpolateNode = sgsdk_CreateShadingInterpolateNode "InterpolateNode"
sgsdk_ConnectNodes InterpolateNode 0 DiffuseTexture1
sgsdk_ConnectNodes InterpolateNode 1 DiffuseTexture2
sgsdk_ConnectNodes InterpolateNode 2 BlendColor

DiffuseTexture1 = rt.sgsdk_CreateShadingTextureNode('DiffuseTexture1')
rt.sgsdk_AddAttributeToNode(DiffuseTexture, 'DiffuseTexture1mapChannel', 3)

DiffuseTexture2 = rt.sgsdk_CreateShadingTextureNode('DiffuseTexture2')
rt.sgsdk_AddAttributeToNode(DiffuseTexture, 'DiffuseTexture2mapChannel', 3)

BlendColor = rt.sgsdk_CreateShadingColorNode('BlendColor')
rt.sgsdk_SetDefaultParameter(BlendColor, 0, 0.5, 0.5, 0.5, 1.0)

InterpolateNode = rt.sgsdk_CreateShadingInterpolateNode('InterpolateNode')
rt.sgsdk_ConnectNodes(InterpolateNode, 0, DiffuseTexture1)
rt.sgsdk_ConnectNodes(InterpolateNode, 1, DiffuseTexture2)
rt.sgsdk_ConnectNodes(InterpolateNode, 2, BlendColor)

rt.sgsdk_ConnectNodeToChannel(InterpolateNode, DirectXShader, 'Diffuse')
rt.sgsdk_ConnectOutputToDirectXMaterial(effectFile, 'Diffuse', 'DiffuseTexture')
