AccuRender nXt

advanced rendering for AutoCAD

Just testing AR Studio.

Does anyone know what the channels are when editing textures.

For AutoCAD I don't think you need to manipulate this-- leaving it alone should work.  It's there for other applications (Rhino, Sketchup, etc.) which permit multiple sets of texture coordinates on the same mesh-- native AutoCAD doesn't really support UV texturing at all.

Okay. Another question on textures:

In nXt you can layer different textures and bump maps to create a more complex material. For example, the Oak veneer material (image attached) uses two bump maps: one for the grain and one for the flecks.

In Studio I can't see how to achieve this.

A further question: What is a solid texture?

Currently only one texture per component and one bump map.  There is a blended material which allows more complex permutations-- most people do texture blending in photoshop.

Solid textures refer to the granite/marble/wood procedural textures.  They're now lumped together-- you can choose a procedure in the interface.

"Here's the latest render using metallic materials. The chrome now looks a lot better. I do feel though that the reflected light on the back wall is too bright."

"Pacing a mirror on the back wall (reflections = 1.0, noise = 0.0), you can see the difference more clearly (top image is nXt)."

"You can see from these two images that there is definitely something wrong with reflective surfaces. It appears the light is being reflected, but not objects or textures. In the nXt version (top image), the carpet texture is being reflected in the…"

"ARDECAL now works. Here's the image after 10 minutes of rendering. I do have a slight concern that reflective surfaces seem rather dull. This is particularly evident on the end frame of the desk and the base of the chair."
