ive had the same problem in editor, probably if the png has _ALP at the end you have to remove it

if it says Colour type RGBA but A is not required, means you have to put _ALP at the end

"Colour Type RGB but A is required" means the texture was saved without the alpha channel for transparency, but the texture cutout material property "Alpha type" is set to "Alpha".

There are two ways to fix it, depending what you want to achieve:

You want a texture with transparency

- Save the PNG file as a 32-bit image (including the alpha channel)
- The file name must end with _ALP, for example TextureName_ALP.png
- In modeller in cutout mode, the cutouts that use this texture page must have the material property "Alpha type" set to "Alpha".

You want a texture without transparency

- Save the PNG file as a 24-bit image (without the alpha channel)
- The file name must not end with _ALP, for example TextureName.png
- In Modeller in cutout mode, the cutouts that use this texture page must have the material property "Alpha type" set to "Solid".
