Problems with Opacity Maps Not Displayed When Exporting Textures.

[lee0909]

안녕하세요, 출력 템플릿을 2D 뷰로 설정하고 텍스처를 내보내면 불투명도 소재가 표현되지 않습니다. 알파 블렌딩 쉐이더를 적용했는데 3D 뷰포트에서는 투명하게 보였지만 텍스처를 내보낼 때 투명해야 하는 영역이 불투명합니다. 답을 아시는 분들은 제발 도와주세요.

Hi @lee0909,

Thanks for the message.

Can you show us a visual of the issue? Where are you using the Opacity map? What's the export preset?

Let me know.

[lee0909]

This is my export preset.

[Cyril Dellenbach]

The 2D view export preset will always export precisely what's in your current 2D view.

Therefore, if the Display mode is set to Material (as it natively is), the exported map won't be an Opacity map, but the entire material as preview in the 2D view.

I advise you to switch the output template to PBR Metallic Roughness. This way, the Opacity map will be saved in the Alpha channel from the Base Color. You'll simply have to display only the Alpha channel of the Base Color in the dedicated slot of your rendering application.

Regards,

Is there a way to export to one map when non-transparent and transparent materials are together in 2d view?

Hi, if you set the output template to 2D view and export the texture, the opacity material will not be expressed. I applied a pbr alpha blending shader and it looked transparent in the 3D viewport, but the areas that should be transparent when exporting textures are opaque. If you know the answer, please help.
