Thank you, everyone.
However, the method you taught me is different from what I was aiming for.

I also referred to the video that SSmolak taught me, but I realized that perhaps I needed a different approach to achieve what I was aiming for.

I would like to know the settings to override.

Is it possible to set the projection type of a texture to UV by a node even if the projection type of Cinema4D's material tag is set to Box?

On the other hand, I know that even if the material tag's projection type is set to UV, it is possible to project as a Box type using Trip lanar.

I asked ...

Thank you Frankmci!
I was able to solve the problem using the method you suggested.

In Mac's Retina display environment, the resolution is 144ppi compared to the normal 72ppi, so the resolution of LiveViewer becomes too high and wastes power.
72ppi
I think it would be more comfortable to use if you could set it yourself, such as displaying the rendered version at 4 times the size.

It's solved!
I was not aware of this command.

Thank you

Just loading textures will crash.
If you load an existing scene, sometimes you can render it, and sometimes it will crash when you try to render or edit the material.
