When using the Translucent Blend mode for a portion of a model, the mesh is distorted

Hi there! I’m having a problem, as shown in the picture, when I replace a part of the model with a material that uses a Translucent blend mode, the mesh of the rest of it becomes distorted, but with other materials that don’t accept the opacity parameter, the mesh behaves normally. Is this due to the model itself or the rendering of the blend mode? Is there anything I can do to fix it?
(The model was found and imported from the internet, and the model itself includes several parts that use different materials. I apologize that I no longer have the original location of the model)


Not an expert, but at first glance it almost looks like an LOD change is being triggered for some reason, given how most of the smaller details vanish, the reduction of apparent geometry. I can’t say why that would be the effect when all you’ve done is changed a material though.

Thanks, this gives me direction!
