How do I apply these maps?

So these maps are for an .obj file and the folder didn’t come with any .mtl. I am rendering with Vray and when I try to apply the maps, they look good in the rendered viewport, but when I render with vray they look blurry. I just don’t know how to apply them. Is the purple one a bump map? Is the B&W one a displacement map? Im just confused. When I tried the displacement my computer crashed.


Hi Aiden,
Normal map stores data about surface direction, each shade means different orientation of the pixel.

More info here:

I would suggest to start with Color as a diffuse map and Height_map as a bump or rather a displacement map. If you want to use the normal map for a bump, change the Bump Type to a Normal map.
