Simple Render Technique Maya

KHM3dia

So i finished modelling my rifle model and because i dont want to texture it, im planning to use default materials within maya, i still want to achieve believable renders. Somewhat like this

Can anyone suggest some tutorials based on what i want to achieve?

The examples you shows are fully textured. You won't be able to get that level of render with default Lambert material.

What you can possibly do is ambient occlusion render, or pure white material with HDRI light. You'll get something like this.

You can do a lot with procedural textures in maya.. but you're not going to get the same result as a fully textured model without a *lot of work. Probably more that just texturing it in the first place.
