Slim template error

[playmesumch00ns]

It tells you exactly what you've done wrong in the error message.

The key is these lines:

ERROR: "MBlend_0.sl", line 93: ERROR: argument mismatch for function "mxslMBlend"
ERROR: Possible choices were:
ERROR: <unknown type> mxslMBlend(color; color; float; float; color)
ERROR: Your call was:
ERROR: float mxslMBlend(uniform float; uniform color; uniform color; uniform float; varying color)

When you write a slim template using RSLFunction you have to define a function inside the RSLFunction block, then define a matching parameter interface in the slim code above it. If you look at the parameters you've declared, you've got

color,color,float,float,output color

whereas in your function declaration below you've got

float,color,color,float,output color

The order of the parameters in the slim part must match the order of the parameters in the RSL part. Simply put your "Mode" parameter first in the function delcaration and it should work.

For this reason I much prefer using the DynamicFunction-style slim templates. Slim handles building the function declaration for you, so you can change the parameters as much as you like, and you also get access to more functionality.
