IRender Nxt vs Vray

Hi, I have been using Irender Nxt for a while and i am quite happy with its ease of use. However the quality of the renderings are only OK. I am wondering if it is possible to achieve the same quality as Vray with IRender Nxt with some more practice, better textures etc.

I have been doing som testing. It seems that the first low resolution teak texture I used somhow was overriding the new texture. I tried do delete the floor and draw it again and then I imported the texture again. Now it works fine.

Thanks for the update.

We'll see if this is something we can fix to prevent it from happening again.

Richcat - I started a new thread about importing Arroway textures so we can check it out better:

Depth of Field and Depth Blur

Another thing in the V-Ray image you referred to was the use of depth blur:

V-Ray image:

The flowers at the front of the rendering are in focus, but the lamp and other items further back in the room are out of focus.

IRender nXt has two different ways to set focus. The Focal-Distance/Depth-of-Field settings on the Render SetUp tab can be used to set focus before rendering. The Post-Processing Depth Blur feature from the FX icon after rendering can be used to set depth blur after rendering.

Here is an image rendered without depth blur:

everything is in focus.

Here is the same image with the focal length set to match the lamp and Depth of field set to 0.3

The lamp is still in sharp focus, but other items are out of focus.

This third image took the first rendering, and applied the FX Depth Blur to it.
This is a simple process because you can see the blurriness as you move the slider bar.

Harsh Colors

One other thing about the V-ray image is it uses much more subtle colors. This is the choice of the modeller. I generally use harsh colors - because I am trying to see the effects of the things I am working on more easily and also because I am partially color blind so the brighter colors are easier to see,
