When the tool is active, the list of blend modes can be found in the Tool Bar, along with the additional mode of Overwrite.

Line/Curve tools all have options to utilize a blend mode as they are used.

Not all blend modes are easy to understand in classic or intuitive terms, and because of this experimentation is recommended.В The forum is a great place for asking questions, getting tips and discovering how to use the less intuitive features of. The order of the layers in the layers stack is important when using layer blend modes.В Layer A blended over Layer B is not the same as Layer B blended over Layer A - even if the same blend mode is used. In the dialog the Blend Mode drop-down list offers 14 blend modes.Д¬lick one to apply the blend mode to the layer.В The new blend mode will be applied to the entire layer.В It is not possible to apply a layer blend mode to part of a layer. To change a layer's Blend Mode, open the Properties Dialog for the layer by highlighting the layer in the Layers WindowДЄnd pressing the function key F4.В Double-clicking the layer in the Layers Window is an alternative method of opening the same dialog. Performance was acceptable in all cases, but obviously the TMU usage for Sobel makes it a little slower.Revision Date: 14 April 2021 Layer Blend ModesДЄ layer's blend mode specifies how it is blended with the layers immediately below it in the layer stack.Д¬hanging the Blend Mode on a single layer can radically alter the composite image. In general the pre-generated normal map from a file (first branch) was highest quality with Sobel second highest and the third the worst (but still not terrible). Where int() returns the integer portion of a floating-point value (basically float-to-int conversion/truncation), and frac() returns the fractional portion of a number (or N - int(N), which results in a floating-point).ДЇloat3 FetchNormalVector( float2 tc, uniform bool readFromTexture, uniform bool useSobelFilter )Should be pretty straight-forward which bits are relevant. We can also use the fact that Z = в€љ(1 - X2 - Y2), and add an alpha channel, to get 16-bit precision for X and Y using 8.8 fixed-point (at a higher computational cost of course):

The typical conversions from vector-space to 8-bit color-space and vice versa are: It doesn't really matter what this TBN matrix is as long as N is perpendicular to the surface, since the traditional lighting equations are based on a Lambertian (N.L) reflectance model that is rotationally invariant around the surface normal. This matrix is used to transform into tangent space. What you usually do is only store the per-texel normal (which is already in tangent space using the appropriate gradient operator), and then generate a single TBN matrix for the entire textured surface at runtime.
