Highlights and Reflections
I've been using IRender for sometime but have never been able to figure out Highlights and reflection settings.

How can I make my walls appear white?
My walls appear white in SketchUp, but when I render them they are grey White Walls and White Backgrounds are often a challenge. You can make walls whiter in IRender nXt using a combination of Self Glow and the Brightness Slider .

How can I balance the sun, sky and artificial lights?
There are a few good methods:

My Transparent Curtain is rendering like glass
Recently a user on our forum asked: "I placed a semi-transparent shower curtain in my model, but it rendered like glass. What can I do to fix this?" This is because IRender nXt, by default, treats all transparent objects in SketchUp as glass which reflects light and distorts objects behind the glass. Most transparent objects in SketchUp models are glass, so the default is to render them as if they were glass. You can reduce or eliminate this effect by lowering the Index of Refraction to 1.0

Reflections in multiple mirrors
I just noticed that IRender nXt doesn't seem to know what to do when you are looking at a mirror that points back to a mirror, which looks back to the original mirror. By default, we only process a couple of levels of multiple reflection. You need to change the setting for Reflective Bounces.

How can I Render Water and Waterfalls?
I am trying to render an image with a pool in it. Can you suggest anything like a preset, download (like with the grass) or tutorial to help me create realistic looking water? Thanks! Also I'd there a way to make the water look like it is falling? Like a waterfall or water feature.

Low Resolution Renderings
I just downloaded your free trial and rendered a quick design and it turned out looking good but the file size is 98kb and is really fuzzy when I zoom into picture. I didn’t find any help with this and I am used to most renderings being mb’s so I just wanted to see what I am doing wrong. You can set the desired resolution on the Render Setup Tab.

How to backlite a box on wall

I have speckled lines of light leaking through my walls
A user was getting speckled lines in his rendering at the edges of walls.

Can I reduce the amount of aliasing at edges?
Angled lines between two materials can produce a jagged effect. By using Anti-aliasing, IRender nXt reduces the amount of this effect.
