However, if you have created the *Substance Shader* manually, the required link to a Substance Asset will still be missing and the shader cannot function. In this case, a warning symbol will be displayed as a preview image of the shader (see image below). ![Image: 2024-0_Substance_Shader_02.png](https://help.maxon.net/c4d/en-us/Content/Resources/Images/2024-0_Substance_Shader_02.png)\ Without a correct link to a Substance Asset, the Substance Shader cannot function and **channel selection**will also not be possible. ### Asset Parameter ID: `SUBSTANCESHADER_ASSET` Here you will find the link to the corresponding Substance 3D Asset. Select an asset from the *Substance Asset Manager* here (unless one is already linked). To do this, you can assign a loaded asset from the open *Substance Asset Manager* using drag & drop, or first click on the pipette symbol to the right of the **Asset field** and then on the desired asset in the *Substance Asset Manager*. Without a valid link to a substance asset, the subsequent **Channel parameter** cannot be used, either.\ Use the small triangular menu to the right of the **Asset field** to access commands for **deleting** the link and for selecting or displaying the linked asset.\ For manual assignment, you can find the *Substance Asset Manager* in the *Extensions menu* under the *Substance Engine* entry. ### Channel Parameter ID: `SUBSTANCESHADER_CHANNEL` Of all the output channels provided by the linked asset, one can be selected here. The corresponding texture will then be displayed by the *Substance Shader*. The resolution of these textures can be specified via **Width** and **Height** in the settings of the linked substance asset in the *Attribute Manager*. To do this, select the relevant asset in the *Substance Asset Manager* to display its settings in the *Attribute Manager*.
