Hi Roy, this is my first render using nXt full version. I used 5 channels for sky, sun, point lights, omni lights and object brightness, in this order.
I used very low values for sun and sky, because in many times, they "burned" the wood of the floor. Is too difficult to me improve the illumination effects, so I decided question you about some tips.
I expect your comments, thanks a lot! - Attachments:

Hola Juan Manuel, ¿Salvaste el archivo .nxt?, lo interesante de estos renders es el resultado después de trabajar sobre ellas con el editor de imágenes?
Saludos,
Alejandro

Uh, no, no lo guardé, pero antes de retocar la imagen final, estuve jugando un poco con los controles de los canales. La verdad que es muy bueno!
Lo que no logro comprender es cómo se setea la dirección del Norte y el sol. No entiendo respecto a qué parámetrosson los ángulos, principalmente el Norte y ladirección del sol en planta, no consigo que el sol venga de donde yo quiero!
Gracias por la ayuda, saludos

Si quieres postea el archivo.dwg y con gusto le doy un vistazo, el principio básico es que el Norte de tu dibujo es tu Norte. Guarada siempre el archivo nxt, asi podrías ver que ocurre si no hay luz exterior, o luz indirecta, etc, o bajar al mínimo determinada iluminación. Hay muchas opciones dentro del editor.

Always provide nXt with accurate lighting values whenever possible. Make sure the drawing units are correct-- this is particularly important with artificial lighting. Start with the sun and sky intensities at the default of 1.0. Add a little cloudiness if you prefer, say 0.7. Some general tips on lighting can be found here. Some tips for combining daylighting and artificial lighting can be found here.
If you want to send the model and/or the .nXtImage file I may be able to help a little more here. Use Support->Upload a File to upload large files.

it occurs to me that one of the most common mistakes in arnxt is setting the correct drawing units. Maybe adding somekind of a button in nxt could be a help, no? And by the way, i still believe that the possibility of giving names to lighting channels would be a big improvement. I believe this already exists for nxt for sktechup

CAN WE GET PETER MILNER TO TRAIN SOME OF US FOR A TOKEN ?
Good day, forum members,I was thinking that we could each, if interested, contribute a significant token to give Peter Milner and David to train us virtually in nxt render for Autocad. Am not sure he still uses it but the experience he has spanning over 20 years cannot be underestimated. I wish the forum co-ordinators could look into this. So that more of us will produce realistic renders with the paid version of nxt render and we will be able to encourage other users of other more advanced…See More
