Blue Material

[JHuman]

I have tried and tried....
This material on the door and windows always comes out blue. Usually this happens because the backside of the face is the SU deafult material. Not in this case, I have reversed, and applied the material, redrawn the object several times. It is just a single rectangular face with the frosted glass type material applied on both sides. These always come out blue, note the glass in the storefront is the same material. Any help would be awesome!
Thanks!!!!

Re: Blue Material

I have attached another image from the same model. One of the panes of glass shows up ok, but the other's dont. They are all components.

Re: Blue Material

mmm i just started with vray this week... i got a lot of problems myself!!!! cant even import the free materials, but i read that probably cause of a newer version....
perhaps you need to make a double layered material of... i think! cause glass is transparent. when you make a material instead of chosing vraymlt chose the other. Those the glass have volume???

Re: Blue Material

Is the refraction map enabled?

Re: Blue Material

OK, I'll throw my hat into the ring!

My guess is that the offending glass has thickeness, but is not enclosed for some reason, and that one or both faces of the glass have the default colour (blue) on its back face. To check this, in turn, select each face in SU and interogate the 'entity' information in the context menu. If one side has glass and the other side has defualt, then I would say this is the cause.
As for fixing it, well I'm no 'thick glass' expert, so this may not be correct, but I would either re-create the glass as a complete and enclosed unit and apply the glass material to the whole unit OR I would make sure the back face of the glass (ie the 'entity' has glass applied to it - I'm not sure which would be correct, but suspect that either would fix it. . . . . but I could be completely wrong!!!

Also - make sure that you are using the vray glass meant for 'thick' glass, there is also an architectural glass (DCA Glass) which is meant for single layer glass i.e. window glass as viewed from outside, and this shouldn't be used for 'thick' glass.
(The original material library explained the use of the materials in more detail - this explanation seems to have got 'lost' in the new downloads area)

Re: Blue Material

Thanks all for the replies. DCauldwell, that was my first thought, that the backside of the face was still the default material, its happened many of times, but usually when I apply the material to it, goes to normal (usually).

I did use the vray material. I went through a list of about 10 different things, none of which worked. The glass is a single face material is applied on both sides. I also did try the double sided material, and I always apply my materials through vray. But, this time I also tried through SU.

Thing that puzzles me is they are all components, so why is one door showing up different (2nd image) and then the same material is applied to the exterior windows (1st image). That could be due to the amount of exterior light coming in.

Not quite sure what to do. Thanks for the tips.

Re: Blue Material

I have or had the same problem with 1 of my scene's... I also had some blue and some normal acting faces. So why acts correct and the other not, that's a mistery to me

Lousy rebel faces, (quoting Homer Simpson) "If I had a gun I'd show them a thing or two..."

Re: Blue Material

Well I'm afraid that has me stumped. One last thing, have you checked that the faces are correct, i.e. do a view by normals to see if you have any reversed faces.

Good Luck - over and out!

Re: Blue Material

I wouldnt think that would matter since it is a single face. If they are reversed it would essentially just be the back side of the glass, which I applied. When I apply materials to objects like this I select all in that group / component and apply to selection. Then reverse faces and repeat.

Re: Blue Material

Make sure also you don't have 2 planes in the same position. For example, one plane could be the glass mat., and the other one the blue mat.

Delete the sheet of glass and see if there's another one!

Re: Blue Material

I did that too, I think Ive redrawn the face several times. I have also made a new component, a new file, etc. Still blue, just depending on what camera angle, some of them are blue and some are normal.

Re: Blue Material

I think it might be a bug. I've had this problem with transparent material as well. Some times a blue colour appear while it shouldn't.

Re: Blue Material

That was my thought after running through all these different options. I did uninstall SU and vray and it seems to have fixed numerous other problems I was having, but the blue windows still stand, guess it will be a photoshop fix for now.
