Function Documentation

ED_wpaint_blend_tool()

float ED_wpaint_blend_tool	(	int	tool,
		float	weight,
		float	paintval,
		float	alpha )

Parameters

weight

Typically the current weight: MDeformWeight.weight

Returns

The final weight, note that this is not clamped from [0-1]. Clamping must be done on the final MDeformWeight.weight

Note

vertex-paint has an equivalent function: ED_vpaint_blend_tool
