What's wrong with this model?

Hi!

I am trying to make an interior with VIZ4 and V-Ray. I attached a panoramic rendering of the current situation. Uhhh. Do you have any idea what causes these striped artifacts all over the image? Thanks.

I don't use Viz but maybe you could try precalculating the irrad map with a box type camera so that you end up with a 3x360 degree distribution of samples.

Are you making the image through any glass????

[tom schuelke]

maybe you have to use the option

"use max compatible shade context".

its a button in the rendersettings.

only a suggestion.

good luck

wow..that looks like impressionist art to me

I think what jbug is suggesting would work. Thats what happens when the saved irradence map is different fromt he image that is being rendered. In your case, the irradence map was calculated at a different setting than the panoramic view.

i definatly think you lack irradiance samples there, are you using a presaved irr map?

[rozsadan]

The problem was the old irradiance map. Thanks guys a lot!

Hmm, but i still dont know how to accelerate renderings of panoramic images. I tried several settings but none worked considering the irradiance map. The single frame and do not delete end, switch to saved map supposed to work for panoramas, but i receive the same artifact that on the first attached image. any ideas how to calucate the irradiance map once and then render the panoramic image?

Have you tried the the box type camera?

[rozsadan]

i might be ignorant, but whats a box type camera?

[J_Bug]

It's one of the VRay specific camera types in the "Camera" rollout section of the Render Scene window. This will render a cross shaped image that when folded up creates the six sides of a box. When you render the Irrad map with this camera it's going to create samples in more all directions rather than just within the cone of a standard camera.
