When this input type is created in the ExpressionME-L Node, you can connect thinkingParticles' TextureMap Node and use its available data to transfer colors to particles or to use color information from a texture map to control particle simulations.
This input cannot be used to create custom materials or surfaces, but it can be useful for creating realistic simulations that involve extracting colors from textured surfaces.
Global Variable:
| texturemap_in_id | returns the index of the input you created (starting with 0 excluding Time and On). |
This function is used to evaluate the color with alpha or without or the mono value (intensity) of a texture map.
Code:
texturemap_in_eval(in_pos, out_scalar)
texturemap_in_eval(in_pos, out_vector)
| Parameter | Description |
|---|---|
| in_pos | The position for 3D maps or UVW for 2D maps. |
| out_scalar | The mono value. |
| out_vector | A vector of length 3 ([r, g, b]) for color, or a vector of length 4 ([r, g, b, a]) for color with alpha. |
Evaluates an intensity gradient
Code:
texturemap_in_gradient(pos, value)
Input:
| Parameter | Description |
|---|---|
| pos | the position for 3D maps or UVW for 2D maps |
| value | vector[3] for a 3D gradient or vector[2] for a 2D gradient |
Output:
| Return | Description |
|---|---|
| scalar | 0: fail, 1: success |
This function evaluates a turbulence vector for a TextureMap Node.

| value | vector[3] for a 3D gradient or vector[2] for a 2D gradient |
Output:
| Return | Description |
|---|---|
| scalar | 0: fail, 1: success |
