I appreciate your comments, and I agree that it serves our purpose best if images on the Gallery are directly from IRender nXt - or at least make it clear that they were post-processed. We depend on the images on this site to give potential users a realistic preview of what that will be able to do with the software.

There is some "post processing" which can already be done using IRender nXt. The brightness slider is the most obvious. This is very important to making an image look the way you want. We provide an automatic "Photometric" lighting adjustment, but t may make some scenes lighter or darker than you want.

And of course, Lighting Channels, is a very valuable "tweak" to quickly post-preprocess the balance of sun, sky and lights in the model without having to re-render.

Other post-processing "tweaks" are available in the Image Editor, such as Haze and Depth Blur

We are about to add a new "tweak", which will let you adjust the color of a material, by clicking on a pixel which is rendered with that material, and using RGB sliders to adjust all pixels from the same material. This will not adjust reflected light from the material, nor reflection from the material.

But we think if will have great use for some materials - especially fabric colors when rendering furniture layouts. And if you want the reflection effects, you can then change the material for real and re-render. I'll report more on this when it is working.

If there are some simple tweaks which we could add to IRender nXt for post processing, then we could add them and then, fairly, submit images which were not post processed with other software packages. I'll take a look at a basic contrast filter, and you may want to add some other ideas.

Post any thoughts and ideas you may have to this thread.

Does this mean you do not want images uploaded that have post processing ?

I think we need to allow post processed images, and encourage them, but you might include a comment that it included post processing so that people will know that the image includes features which are not native to the rendering package.

The main purpose of this thread was to see what easy types of post processing we should add to IRender nXt.

Contrast would be very good - also colour temp if possible - renders tend to towards the cool side - look forward to changing material colour post render
