LuxRender v0.6 Release Candidate 1 - Windows/Linux/MacOSX

[MadSwede]

hi everyone

i'm using 0.6 RC1 and Blender 2.48a on Vista 32 and am still quite new to LuxRender.

could it be a bug in the RC that fonts / texts are not rendered? because when i render text its invisible in the rendered image.
when i convert it into a mesh then its visible again.

I think it's just a limitation of the exporter. It can export curve objects so it'd be smarter to convert the texts to curves to maintain a higher level of control.
In the end, what is exported is the visible end result, i.e the vertices and normal data.

I hope I'm not spreading misinformation, I'm not a senior user myself.

Hi all.

the scene:
plane with mate material
crystal (cube) with the normal outward
sphere with Glosy material

Rendering: 2 Final - MLT / Path Tracing (exterior).

1. fused silica glass

2. + Architectural

.....

In the second case (+ architectural) is possible to see the sphere behind the glass but poorly lit and casts no shadow.

The shadow of the glass is very strong.

Neither shows the edge of the glass.

Greetings
Tony.

Hi,

that would be normal behaviour, 'architectural' glass is a proxy material for efficient rendering of windows in interiors,
it does'nt transmit light, and does'nt allow light to pass trough it only trough the side where the normal is pointing,
thus in an interior when the normal points inwards, it can be lit.

as such, it's only meant to put as single sided glass windows in an interior render

Oh, thanks Radiance.

Ignore the nature of architectural glass.
I am really surprised.

Only use is indicated in the interior windows?

we are at this archglass thingy one more time

I'm using it on jeanphi's advice with normal meshes (closed not singlesided like planes).. I'm thinking about archglass as something similiar to ztransparency so where I don't need refraction I use archglass

here is example, everything's seems fine (except not light showing in reflection of lamp in archglass *red dot)
there isn't any normal glass - everything is archglass.. even this 'frozen white glass' is mix of mattetransluent and archglass

hey radiance and jeanphi please you must definitely nailed down correct use of archglass before v0.6 is out

Please stop saying this as I have to correct it afterwards everytime

architectural glass is meant to be used like normal glass, with 2 sided panes. The only difference between the 2 is that architectural glass does not bend light beams so light can pass through without being occluded.
In RC1 I had however to remove this optimization from bidirectional because it caused wrong renderings in certain cases. It turned out that the problem wasn't in bidirectional but in arch glass itself and everything is now fixed and should work as expected in RC2.

I've got it right here all the time, in the documentation forum: viewtopic.php?f=25&t=1584&start=0#p14128
