Hi,

not sure what is causing the following two things in the image, so I am hoping for some help.



1 these two downlighters have the same materials attached as all the others. I also have a hdri in the reflection slot of the VRay render dialog box under Enviroment. So I don't know why it is turning out black.

2 I used irradiance map for the first bounce and light cache for the second bounce. I also applied a max camera correction modifier to the camera. Would that be the cause of the "dirty" ceiling"

Lastly what can I try to have my ceiling render more white, it has a white VRay material applied to it at present.

Thanks

Could be the cammera correction : As in this case the V-Ray Message Box is giving You back a warning...

As for the ceiling, this is due to Color Bleeding...
#1 Solution is to apply a white material on the walls, save the IR, and then reapply back the yellowish one, but read the IR file... thus Ur ceiling will get whiter...

#2 Reduce the Saturation in the GI. Close to zero 0.0

Best regards,
nikki Candelero

are you using bucket mode? i can see the different buckets. also it looks like you have co-planar faces making things messy. as for the lights i would need to see settings on the material.

Thanks for the advice!

Candelero, are you referring to the saturation setting under post-processing in the VRay render dialog box?

Da_elf, yip I used bucket mode, why do you think would it be visible? I model in MicroStation and export to Max, but on this job I used the linking function and am still getting acquitted with it, so yes there are some odd surfaces.

This is the setting for the material:

[Da_elf]

well. A: your bucket mode. you can see it on the roof. looks like its checkered. basically when using bucket mode each bucket is calculated independantly and the edges of the buckets dont usually blend well. when doing single frame mode though vray will take all the samples and blend them nicely so your render is checker free (unless you use the checker material hehehe)
B: basically when i get my blueprints from any of my clients i just use them as reference and never use their lines for my model since sometimes i can find 6 different splines overlayed on 1 wall meaning there would be serious problems with co-planar faces.
C:its rather strange about that light. dont know whats wrong with it. a little suggestion though about your material. for a metal i would use a light gray diffuse

are you using linear color mapping?

Hi

try unchecking, Check Sample visability.

Just with regards to co-planar faces. I have this problem with models partially completed by other people who have pluged gaps with sections of walls etc but which do not intersect properly and as a result overlap. Fixing all of this up in Archicad prior to exporting is a pain but it has to be done, which is the same case with microstation im guessing.

You can pick the overlapping faces because they render out dark. It looks like you have this problem on your downlights, the edge of the bulkhead where the recessed lighting is, and on the lift surround. I'd be checking all of these things. you can usually fix this in max manually by modifying the mesh and deleting certain faces, but im sure theres a tool out there somewhere that checks for coplanar faces. Also, it looks like you may be using max's colour correction (could be contributing to the really saturated look) which personally i'd stay away from but this is personal preference though.

jacksc02 - yip I used linear color mapping

natty - if you are refering to the switch under the irradiance drop down under advance options, it was unchecked.

paulison - max's colour correction, if it ain't on by default I am not using it. Can you please tell me more about it. Where do I find it to chech if its of or on.

Thanks all

Rather than guessing what your problems are why dont you share the scene so we can have a look.

Hi Natty,

With pleasure, what site would you recomend for the hosting?

Also remember that the data is displayed via File Link in Max, so I will up load both the Max and DWG file, but have never shared data like this so I don't know if it will come out correctly on the other side.

[natty]

If you unbind it in max then winrar the max file with textures and mail it to me and i'll share it on my ftp for you.

Hi

Are you using max8? .... my max wont load your file? (max7.5)
