transparent window problem in beta 3

[epinox]

Maybe there is another topic about this but i have been looking for 2 days and never found anything. I had too many renders and never had them transparent. I had them reflect but not transparent...

Help me obi1 you're my only hope...

I moved your post to here because I'm guessing this is a VfS topic. I don't know exactly what your asking. Are you having trouble with our material editor?

I tried VRAY linked material option from create material but it doesnt show inside; it doesnt have opacity

Ok - try disabling the option "Correct RGB" in our options -> Global Settings section. There is a bug in beta3 where we gamma correct refraction colors and it makes the glass much darker than it should be.

nob it doesnt work;

I disabled vray'linked the grey glass
then i made transparency 129,129,129

then I closed correct RGB but still no transparency

if you'd like you can send me a scene demonstrating this problem - I don't know what else would cause this.

I aslo have some problem w/ architectural glass. What's the difference for material setting between single plane and dbl glass?

Single sided glass- this is ment for just simple surfaces or planes and not closed solids. Just have a reflection layer (you should probably map fresnel reflections), then change the transparency to a shade of gray depending on the amount of transparency that your going for.

Double sided glass- this is ment for closed solids. You need a reflectionlayer with fresnel mapped. Change the diffuse transparency to white (completely transparent basically). Add a refraction layer and your good to go. Generally its a good idea to have Affect Shadows checked as well. In order for refraction to work properly the geometry must be a closed solid because refraction needs an entrance surface and an exit surface.

Changing the color of double sided glass- the most accurate way to change the color of a refractive material (glass) is to use fog. For the fog color pick a desaturated version of the desired color, and use the fog multiplier to adjust for the desired effect. This method is dependant on the thickness of the material, so tests to check (the material preview may not be accurate). The second way is easier, but less physically accurate. All you have to do is change the refraction color to the desired color (see told you that was easier )

Thanx. I finally managed it. Now my windows are transparent but when i render my view from outside my walls seem to get too much light and its all bright everywhere...

Is this a problem caused by the caustics? I always turn caustics on cuz one of my max-renderer :P friend told me when i first started using...

I'd have to see your scene - are you saying that exterior renders weren't bright before? Are you using the Sun/Sky?

transparent window problem in beta 3

It was too bright so i loaded default and added sky to GI and bacground at the envitonment tab.

The thing is now my clours are fading. I couldnt find the seetings to the first render I took to take other renders without the shadows or light(the colours are so live in the first one that I can give up shadow and sunlight )










Update: I found how to take first render again with live colours; i used gi_qmc_lc_very_high.visopt. But still i dont get any sunlight or shadow while using "gi_qmc_lc_very_high.visopt" I tried to enable GI and background but when i enable them and started render there was only brightness no figures or whatsoever on the render so i cancelled... Can you help me add sunlight and shadows to the settings "gi_qmc_lc_very_high.visopt" ???

Thanx again

The reason why your colors are faded are because the default settings for vfsu are set up for linear workflow. So the short answer is that you need to have Correct RGB checked in the Global settings rollout. That should solve the faded colors problem. (if you want I can give you the long explanation)

The physical sun is based off a "model" that tries to simulate real sunlight. And I'm not sure how long its been since you've gone outside and stared at the sun, but its very bright ( ). Subsequently I think you will have to decrease the intensity quite a bit. I haven't worked with it too much (personally I find the physical sun a bit of a hassel), so here is the Spot 3d reference that will help explain the parameters and how to set them up better.

The thing about our vis options files is that they completely restore all of your options, not just a selected few. So my suggestion would be to open whichever visopt file you want to use, add the sun from either our default settings or your own, and save it out so you can always load up a file which has the correct sun settings.

On a completely random note, are you using vfsu on a mac or is that just a mac skin on windows?

At the link that I put on the previous post there are some examples that can be seen if you click at the upper right corner of the page. In all those examples the intensity mulitplier is set to .01. So the default value of 1 is something like 100 times brighter that it really needs to be for an image. Just wanted to make sure that you picked up on that one. Sometimes when numbers are extremely large or extremely small people don't believe that it can be a valid setting.

well first of all I would like to thank all of the mods before asking anything more. I have been reading and reading forums for 2 days while the comouter was rendering and i think i am starting to get to understand vray

When i was trying to have transparency I read in the form that correct RGB is the reason disableing transpareny so i started to disable it every time taking a render. Is is posible to have correct RGB and transparency at the same time in VFS Beta 3 or is it something to be fixed on the latest release?
And should i check correct LDR fixtures too? I really have no idea what it is for...


I use style XP for getting the blue rod off my windows tops so its a skinned xp :P


Thanks for the Help

Re: transparent window problem in beta 3

I think its not Coect RGB because the better picture i took didnt have correct RGB config

So i simply put a rectangular light above; with a 1.5 multiplyer and it seems to be working ok upto this point
