AccuRender nXt

advanced rendering for AutoCAD

Hi, Greetings to all I am doing this image where I have a problem with the use of caustics, I'm using  a solid  with caustics for the pool water material  and the mesh of the waterfall of the same, the effect on the pool is really good, but the effect on  mesh is terrible, if you have any suggestions on how to solve this problem please let me know. Any help or comments would be appreciated, I'm using engine 1 (path trace) in this image.

Regards,
Alejandro 

Hola, saludos a todos estoy haciendo esta imagen exterior  donde tengo un problema con el uso de los caústicos, estoy usando caústicos para el sólido del agua de la piscina y para la malla de la caída de agua de la misma, el efecto en la piscina es realmente muy bueno, pero el de la malla es muy malo,  si tienen alguna sugerencia de cómo resolver este problema les agradezco me lo hagan saber.  Cualquier ayuda o comentario será bienvenido, estoy usando motor 1 (path trace) en esta imagen.

 Saludos,

 

Alejandro

Well; I uncheck the caustic for the  mesh, here is the image with some small post edition in PS, just blurring the palms on the back and the plants on the front.  Also some diffuse glow

Use the Hybrid engine for caustics.  Don't use a solid for the water-- it's easier to model with a thin sheet for the surface (don't tag it as thin).  Hard to tell what else is going on here.

Thanks Roy I will make this changes and see how it works.  What about the difference between the solid and the mesh?

You can try it with the hybrid engine to see what you get.  My guess is you'll need a different (more transparent) material for the waterfall.

Hi Roy, one more question, can you explain me which is the difference between applying caustics to an object or using recflective caustics in the material definion?. Thanks again.  Alejandro

It is a bit confusing, sorry--

To use Caustics with the Path Tracer tag the object with the Caustics switch.  This turns on both reflective and refractive caustics.

Refractive caustics (the kind on the bottom of a swimming pool) are always enabled in the Hybrid engine.  To enable reflective caustics in the Hybrid engine you need to use the material switch.

Hola Alejandro, estoy de acuerdo con Roy en sugerirte de usar un material mas transparente para la catarata. Ademas, podrias tratar de usar un solido (muy sutil) en lugar de la mesh.

Hola Miguel, gracias por tu comentario, Roy sugiere no usar sólidos sino una superficie sin marcarla como delgada.  (hice las pruebas con un sólido y con una malla en ambos motores y no quede conforme) , anexo imagen del msterial que estoy  usando,

This is a remake of one of Peter Milner's scenes. I dont have the file. I photo-matched it in sketchup and rendered in nxt render for autocad.I just retouched it and increased the resolution.
