3ds max Remapping and texture tint issue

Arkideit

Hello recently i have to make a remaping form one UV to another via 3ds max. 
I made it throught render to texture by diffuse channel. But i have two issues.
Render Setings:
Defalult Scanline Render
Filter - Catmull-Rom. Global supersamping - Hammersley
1) Texture that i imported into scene have slight tint diffrence compare to the original one.
2) On remapped texture i have som sort of graphical artefacts, that barely can see, but still noticeable.

UPD. With standart Scanline settings (No Supersampling and Filer - Area) have this pixel issues.

Anyone has some sugestions?

The first issue could be gamma. Try setting gamma to 1.0 before using Render To Texture, which has poor gamma support (it should convert color maps to 1.0 for baking the back to 2.2 for saving, but it doesn't).

The second issue is padding, which is a good thing.
