Nxt materials and cutting planes

archigrafix

I am having some troubles with NXT materials:
I mean native NXT materials... I can't modify them in the way they are created: In the procedural way.

How can we had bumps to an NXT material... For example In a brik wall the joins should get some bump effect.
when I try to render cutting planes I get a message error.

...great soft!!! Integration with SU and easyness!!
thanx

Material Libraries
Do you mean the materials which come with IRender Plus?
The materials in the library are from the older AR3 version of AccuRender.

They can be modified during the selection process. However, you will have to save the modified material and then select the modified material that you saved. (I have not tries this.)

We are in the process of converting the AR3 material library into a nXt material library. Then they will be easier to modify.

Bump Maps
It is better to add a bump map and create a nXt material.

You will need two images - one for the color of the brick and the joins, and another for the depth of the joins.

You can place the first image on the SketchUp material, and place the second image using the Advanced material image and define it as a bump map.

Section Planes
I'll need to try this and see if it is working.

Materials:
I meant that procedural materials (in the library that comes with Irenderplus)
for example brik: when I select the material I can change it but when its applied I should be able to change it with all the options I get when i created it no?
Bump:
I was talking about the procedural materials... not images. When I create a marble material (in Irenderplus) there's no place where i can specifie bumpiness for the veins (for example...)
when I use Sketchup materials (with images) It's easy to do so theres an "auto bump" option.
Cutting planes:
I get this message:
ERROR during: Export Entities and Start Ray Trace:
