Dynamic flow control in materials

I plugged in two textures and it gives me:

MaterialFloat4 Local0 = ProcessMaterialColorTextureLookup(Texture2DSample(Material.Texture2D_0,Material.Texture2D_0Sampler,Parameters.TexCoords[0].xy));
MaterialFloat4 Local1 = ProcessMaterialColorTextureLookup(Texture2DSample(Material.Texture2D_1,Material.Texture2D_1Sampler,Parameters.TexCoords[0].xy));
MaterialFloat3 Local2 = CustomExpression0(Parameters,0.00000000,0.50000000,Local0.rgb,Local1.rgb);
MaterialFloat3 Local3 = (Local2 + Material.VectorExpressions[1].rgb);

Which should be expected, even with dynamic branching. This is because at any moment, the [branch] if (something > something else) could become true and therefore it will need to evaluate the other input.

no and no. it’s not expected, even with dynamic branching. the expected behavior is that if the branch becomes true, it will process the stuff and evaluate it. as such, the texture samplers only need to exist nested within the branches
the code right there is crystal clear. it’s declaring and using your textures and sampling them per pixel, and then making the evaluation. unreal will not execute any further magic beyond what the HLSL code reports.
it’s all explained thoroughly in this thread and I’ve continued to explain it to you, but as it’s clear you don’t want to believe anything except what you tell yourself I’ll just stop bothering
