Render to Texture (Legacy 3DS MAX)

Render to Texture

A RenderToTexture is a realtime engine-generated texture that is represented by a dummy object whose user buffer presents a $RenderToTexture structure.

Note: It is not necessary to exclude the meshes that use this texture from the rendering of the same texture (through the parameter szExcludeMesh) because the engine will do it automatically.

Code example

A code example for RenderToTexture.

$RenderToTexture

{

szID = RealTimeTextureA

szTextureDetail = High

szGeometryDetail = Medium

iRefreshFrameRate = 12

c3BkgColor = 0.2 0 0.1

szCameraName = VideoCamera

$Commands

{

szExcludeMesh = MeshConTroppiPoligoni

}

}

Texture dimensions

If the dimensions go beyond the frame buffer resolution, the first power dimension of two that is smaller than the frame buffer will be chosen.

Parameters

szID

• Identifier (name) of the texture that will be created.

szTextureDetail

• Texture size.

• Default: high

• Range: [lowest .. highest]

szGeometryDetail

• Level of detail of the geometry rendered in the texture.

• Default: medium

• Valid values: medium, high.

iRefreshFrameRate

• Indicates how many frames the texture will be updated.

• If the value is zero (0) or negative, the texture will be updated to each frame.

• Default: -1

• Range [-inf..inf]

c3BkgColor

• Background color.

• Default: 0.1 0.1 0.1

• RGB: [0..1]

szCameraName

• The name of the chamber that will be used to render the texture.

$Commands

• Structure that contains extra commands for creating and rendering the texture.

$Commands Parameters

szIncludeMesh

• Includes this mesh in texture rendering; automatically excluding all other scene meshes.

• In practice, when using this parameter, you must manually specify all the meshes to draw.

• When using this parameter, its inverse (for example, szExcludeMesh) can not be used.

• This parameter is optional, and can be repeated multiple times.

szExcludeMesh

• Excludes this mesh in texture rendering.

• When using this parameter, its inverse (for example, szIncludeMesh) can not be used.

• This parameter is optional, and can be repeated multiple times.
