Diaphragm too narrow gives bright spots in the center of the image. By defect, this cam focus at a few centimeters of distance. In order to focus at some meters, I setup a very narrow diaphragm. Lately, since I use an eight blade diaphragm well defined instead of a cilinder with a controlled "hole", things, programs advance, now is possible to setup a coating ten times thicker than must be (instead of the 100 thicker coating than was setuped the last years), less dispersion, a correct spherical distorsion, less lost of focus in the peripherial, ... better.

HOUDINI APPRENTICE 19.5.303, CINEMA 4D 23, INDIGO RENDERER 4.6.2

Here goes the cinema scene, the materials and the houdini file.

Less than one hour.
Diaphragm very narrow. Pretty good. It can be better. In a days I post the last version of this camera. A lot of changes with the previous.

1 hour, only the flash. The capture simulation illumination introduces a lot of problems actually. Still a little brights with diaphragm that gone with time, but still some ghosts...

8:33, 2450 spp.

No se porqué los árboles sólo se expresan en una parte del terreno (tenga la orientación de cámara que tenga). Sin embargo con la hierba se comporta bien.

Lo de siempre, un esbozo. Tres variaciones de un árbol construído por procedimiento con Houdini (hay que instalar Labs FX. o algo así), una instancia de hierba ( ¿no parecen hortalizas en un huerto? ). Con unas cuantas variaciones más, flores, pájaros...

Mie cumulus necesitaría un repaso. Si utilizas esferas no perfectas está bien incluso en path tracing (esta es bidireccional path tracing). Siguen saliendo bandas purpura-verdes si las nubes no son suficientemente compactas, también a veces si lo son.

31 h, 1273 spp.

Ctz´n se atrevió a soñar. Lo único que te ofrezco son cinco esferas puestas en orden. Investiga si quieres. Es un fantástico sueño...

Si quieres más velocidad rebaja el parámetro "scattering" y prueba a subir un poco el "maximum coefficient of extinction". Ten en cuenta el parámetro "absorption", y el parámetro "offset" en ambos campos del medio.

2 h, 200 spp.

Vamos a llamar a ésta "tattoo".

Es curiosa la complejidad de los "glitches" que genera indigo ...

Los lacrimales están demasiado rojos, demasiado brillantes, ... Por lo demás, suficiente; no pasearé este carácter más.
