vray warning

hello!

i would like to know why i always get those mesagges.

warning:material returned overbright or invalid color. (objet layer:-----)

i ´ve turn down the multiplier of my target lights (with vray lights the problem is the same)
i ´ve used exponencial , linear multiply … with no success at all.
Most of the materials in the scene are standard , could this be the problem? i have used them other times with any problem at all but now i can not avoid this.

regards.
sorry about my english

2

are you doing an interior scene ?
i dont you have anything to worry about its only a warning not an error.

i am working with an exterior scene.

and this warning causes lots of stange white blots that i can not fix.

thanks

manray
are you using any raytrace materials ?

5

not at all , the blots appear mostly in white standard materials (in the building walls)

thank u :slight_smile:

6

and are you giving everything a thickness ?

or perhaps your settings are to high ?

7

everything has some thickness

i am playing with -3 -2 and default settings.

this is the image.

thanks

8

and this is the error

thank u

9

was this modeled in cad ??and imported in as a dwg ?
if so try importing as a 3ds.

10

Make sure all your bitmaps have crop turned on.

11

all the elements that causes the error comes from cad . they are imported with design extension as dwgs .It would be a pity to discard this tool for vray renders. anyway i will try to bring them as 3ds this evenig.

and …thank u gregpetch but all of them have crop turned on.

B&W regards

hi…
here in my jobs i already has this problem…
this is a problem of material…
try to isolate the object and redo the material he has…
in my job was glass eith refract…

Manray, i get that error message too. It occurs when you use HDRI images. Or at least thats why i was told in this forum. From what i gather, you can safely ignore the message. Unless you’re not using HDRI maps, in which case i cant help you im afraid. Hope this does help a bit though.

I had the very same splotches problem! It seams related to coincident faces. As I couldn’t afford to re-import, I had to render with Brazil. If any one knows an alternative for re-import please share.

15

i see we have some different answers for the same problem.

i erase the camera correction modifier and the splotches seem to disappear. it is the only way i found to do it , but i am not to bat and eyelid

try unchecking the max compatible shading context. this checkbox tends to conflict somehow tith technicl camera scripts or camera correction modifier or taper applied to cameras.

17

ups! uptill now it seems to work fine

thank u zerofractal!

regards

i experienced ‘overbright’ warning too, and i assumed it’s from raytrace reflection that i used on some material. after i removed the raytrace, the problem’s also gone. :wink:

I got something smilar but the error was caused by merged NURBS geometry.

I tried to solve this by merging object by object but had no success.
the solution was to convert (in a separate file) NURBS to Polygons.
And export every object to 3ds format.
this way i got rid of those artifacts…

error:

cheers

Brutal, I never got any of these, maybe because I ALWAYS using mesh, no nurbs in max.

I used camera modifiers a lot never got any of these. Interesting to see this, what could be behind it?
