Problem in alpha mask channel for Leaf diffuse Texture

Hello Dear

I export a tree from 3dsMax by datasm

ith in UE5. but when I exported all things are ok except Diffuse mask channel. it does not have mask for diffuse but its correct for corona or vray.
Please help me.

In the details panel under “Material”, do you see how it says “Opaque” for the blend mode option? Change it to “Masked”. You will probably also want to change the shading model option in the same section to “Two Sided Foliage”. See the official documentation for foliage shading.
