wow.

wasn't expecting a "stable' release this quickly.


(like your other releases are so unstable anyway, Ono. Haha :))

Thanks!

:shock: Wow fast development!
You must be up there with Superman and all those other hardcore superheroes or something to be able to pump out releases so fast!

Hi. I made a test of the stable 0.8 and came across an annoying thing about smoothing in my scene. Below you have two images rendered for 20 min. each at 2x this resolution. The scene was not changed in the meantime. It was modelled in Blender with smoothing, but I encountered problems with smoothness when bump maps were applied. In 0.8 test 2 I coped with it by rotating the columns so that the surface was rendering pretty smooth. In 0.8 stable it proved impossible as the the edges stay visible despite my efforts.
What changed between 0.8 t 2 and the stable version causing this or how can I avoid this without playing so much and blindly with geometry?
The image to the left is 0.8 stable and to the right is 0.8 t 2.

Thanks.

Hey Kramster, I think he is referring to the seam in the bump map image showing...

@supraserv, how did you construct the bump map? is it tileable ?

Also, the left image seems to be more orange than the other image...(or is it me?)

neepneep: no, it is not a seam, unfotunatelly. I rotated the columns to avoid the effect, but it always appears where sharp light (sunlight) meets shadow (on smoothed edges). It doesn't occur when no bumpmap is used, but the higher exponent or b feature (my exponent is 0.02 and the b is 0.01) of the bump the more pronounced get the edges of the mesh. But again, it only appears where the light meets shadow.
Below the shaft is the column base. There the edge is extra visible as the values for the bump used there are: exponent 0.2 and b 0.2

And yes, the images are different in colour. This also changed with the version, but it was less importatnt to me.

where the light meets shadow
That's called the shadow terminator I think.

Does Indigo take normals from bumpmaps into account if the rays come from indirect light? Can this be somehow controlled (like it was possible in Yafray and POVRAY?). This is still my struggle with bumpmapped meshes . :cry:
