How to Remove This Color?!

[ichinozori]

Hello everyone, I just registered here and I'm learning how 3D Render using Corona works.
Currently I am experiencing problems related to colors that I don't know where they come from, usually I use another Render and the results are as I expected, but strangely, when I use Corono Render, the side of the 3D object I have has a brown color that I don't know where the source is from. If you know how to make the color disappear, please tell me, because the image should be transparent on the object and not have any color. Thank You

This is the display in 3Ds Max 2023 :
and This is output after Render using Corona :

Hi,

It looks like you have an issue with the settings of your opacity maps.

As Tom said above, it seems like something is wrong with your material setup and specifically opacity map.

 Yep, those areas are cut out via opacity maps, and looks like they are not 0 or 1 (black and white) since it appears there is some partial opacity there. You can try enabling Clip for Opacity (assuming you are using the Corona Physical Material), which is recommended for performance anyway. Other than that, we'd need to see your material set up, and one of the opacity maps, to know for sure what is going on.
