Triangulation lines in geometry when I render

[arturito]

Hi, I am rendering with max and v-ray an scene with geometry imported from autocad (as I have always done without problems) but now my geometry -after rendered- is showing triangulation lines. I am attaching the geometry in both looks: shaded and rendered. Thanks

Try to apply Smooth modifier without autosmooth ..also check for unwelded vertices..

Is not working, I tried rendering with a different light and it render ok. so the problem is on the vray sun light. but I stil dont know what is.

If you are using a Vray Sun, then check the "bias shadow" value. it controls the distance between the object and the starting point of the shadow.

 

What I understand is that: if you have a positive value then the shadow will be far from the object. if you use a negative value, then the shadow will get "inside" the object.. and is the reason of those lines.. (I always use zero with no problems). Do you have a negative value there??

 

-say yes please!-

 

Si estas usando un Vray Sun, entonces revisa el valor del "bias shadow". Este controla la distancia entre el objeto y el punto en el cual comienza la sombra. Lo que yo entiendo es que: Si usas un valor positivo, la sombra se aleja del objeto, y si usas un valor negativo entonces la sombra se va a meter dentro del objeto y por eso te salen esas lineas. Yo siempre uso Cero sin problemas. Sera que estas usando un valor negativo? Di que si porfa....

I don`t know then .. I make my models in max.

Do you have a negative value there??
