QUESTION
How do you fix a texture that is imported with a red tint?

ANSWER
You have applied a greyscale, or black and white texture in your modelling software to a surface.  When it's imported in to Lumion, it shows up as being red.  

Or, you have added a greyscale, or black and white texture to the Color Map for a Standard Material.

For example:



If you change the Imported Material to a Standard Material, you will see that the texture is red tinted.



To resolve the tinting you will need to convert the original texture to an 8 or 24 bit RGB image, or convert it to a 24 bit greyscale image, or use an alternative 24 bit greyscale image.

Then, either:
1. Re-apply that texture in your modelling software and then Reload the model again in Lumion, or
2. Add the texture directly to the Color Map of the Standard Material.  If the texture resolution and mapping requirements have not changed from the original image, then the new one will have the same scale and position on the surface.

Background:
Note that it is not all greyscale images.

It is only those in an old 8 bit greyscale format.  It is not possible to correct the format under DX11, so the developers allowed the texture to be included in the import (rather than reject it), but added red so that it could be used, but also as a 'flag' to indicate it's best to update it.

As a greyscale image, it can still be used with Colorization to set any color.
