Short description of error
When I tried to import a fbx or collada file from 3dsmax 2020 or 2017 with a vertex color data all the data is altered and change the colors. If I tried the same with other software (unreal) the vertex color is perfect in that programs.

I can confirm incorrect colors with FBX file.

No mesh was imported from collada in my case.

@AlbertoVelazquez are you able to import collada file with no issues other than color?
