max.m Posted October 25, 2009 Share Posted October 25, 2009 i can´t get rid of the artefacts in the wall. even if i rise the refl. subdiv. to 128. i think the cause is not the material, but the ies-light in the floor, as around the ies-lights above there are no artefacts in the wall. is there a possibility that i adjust the "quality" of the ies-light, to avoid these artefacts? the only thing i find there is a subdiv. counter in the vray shadow parameters, but tweakening this one brings no result.

Jason Matthews Posted October 28, 2009 Share Posted October 28, 2009 How about the subdivisions of the actual wall material? Are you using IR map? Settings? It may be the light is not sending out enough rays. Link to comment Share on other sites More sharing options...
max.m Posted October 28, 2009 Author Share Posted October 28, 2009 as i mentioned above i rose the refl. subdiv. of the wall mat. to 128. i tried the rendering with the very high settings for ir and lc with no effect on the artefacts. i think the settings and the wall material are not the problem, as i have no artefacts around all other ies-lights in the scene. only around the ies on the floor i get this artefacts on the wall.(you see around the ies above there are none) i don`t know how i can rise the quality of an ies light, as the only subdiv counter there is one to handle the shadows. also tried to rise ths one, with no effect.
