Transparent shader causing strange square holes

[wjj6336]

Hello, Please help me

I made elephant character in blender and export it as .fbx

But I don’t know why, After applying the shader, a square hole is visible depending on the angle.

I’m looking for a method for the 3 days and the normal direction in blender seems to be fine. How can I solve this?

Is this object a single mesh object? Did you check for overlapping faces?

I checked again but it’s single mesh and faces does not overlap…
Could it be that the color is blue but the direction is not reversed?

That looks like the mouth, this is probably a stencil and transparency sorting issue?

This thread might help, I don’t remember the details much myself right now lol.

Stencil Transparency Overlap

The trick I like to use for this kind of effect is to use a depth only shader to “prime” the depth buffer before the ologram shader runs. For a single complex mesh, you can do this with one shader with two passes. But if your hologram needs to be made out of multiple meshes you’ll need two separate shaders & materials per object. Like your example, my initial setup looks like this w/o the additional depth only material. Very similar to yours. [8817724--1200115--upload_2023-2-18_22-22-57.png] …
