Problem with Light Works Render Engine

Jochen Suehlo — Tue, 23 Nov 2004 08:56:43 GMT

I have a problem with Light Works Render Engine rendering a bitmap object.
The quality of the ArchiCAD Rendering is much better than the Lightworks Rendering. Lightworks is unsharp and has white tips.
The object itself defines a Material that has a bitmap picture as texture.
Here the Master Script:

!Material and Texture Definitions

aa=5.8455:zz=7.25
DEFINE TEXTURE 'acertxt_01' '01_acer_bitmap.tif',
a,zzyzx,1,0
acertxt_01=IND(TEXTURE,'acertxt_01')

DEFINE MATERIAL "acermat_01" 20,
0.623529, 0.623529, 0.623529,
0.49, 1, 0, 0, 0, 0,
1, 1, 1,
0, 0, 0,
0, IND(FILL, "Leer"), -1,
IND(TEXTURE, "acertxt_01")

Compare the 2 Pictures. Is there a script that is more adequate to the Lightworks Engine?

The camera light is reflected by the siny surface. You have to define a matte material.

Thank You Gkmethy for the tip.
My Material has a matte surface, so this can not be the problem.
I think there are additional definitions for LightWorks Materials that are defined by "ADDITIONAL_DATA"; I also think that the default definition is a bit unsharp and shiny, so this has to be trimmed manually by script. My experiments got to no result.
But the link to the documentation you applied is very helpful, because here I can find all about Lightworks Material definitions.
Thank You for that
