Saving Texture/Color Information

Hi everybody!

I worked on an object and painted it in Sculptris. I would like to save my Sculptris object with its texture on my computer.

However, I am not sure how to save the color information. If I save the object file (.obj) and the mapping file (.jpg or .png), I still need an .mtl file that includes the information where and how the mapping file is used, don’t I?

Basically when I try to save my model, it always turns in a 3D model without any texture.

I am quite new to Sculptris and the world of 3D modeling and I am very thankful for any information on this matter.
