I'd finally been getting somewhere with daylit interiors in Vue when this awful glitch showed up. If the camera is placed within an imported .obj or .3DS model looking outward the sky turns bright blue without any clouds. This occurs even (in fact ONLY) when there is no glass in the opening. The only way I've found to solve/workaround the problem is to add a sheet of bubble glass with no reflectivity into the opening- then the sky displays properly! This problem even occurs in an imported model with no roof e.g. a walled garden. I've tried everything I can think of- I thought a stray face may have been generated when I exported from SketchUp (Nope), disabling OpenGL, welding/splitting imported models, different atmospheres. The only clue to what is causing this is that inserting an invisible glass face into the opening fixes it, but I don't fancy having to model "glass cases" around my models so that skys appear correctly. I would be very very grateful for any help or advice. Jackson XP 3.2 GHz Intel Pentium 4 1.28 Gb RAM NVIDIA GeForce FX Go5700

Try editing the material of the walls. Even if they are not transparent, they still have that color blue set by default for 'Fade out color' and 'light color'. Set both colors to Black and your problem should go away.

Agiel, Thanks so much for your VERY prompt response! Unfortunately it doesn't solve the problem- I tried changing "fade out" and "light" colours to black as you suggest (and also white) and loading a flat white material rather than the imported white material, but I still get the same effect. Regards, Jackson

I just changed the "fade out" and "light" colours of the ground plane to black and the sky turned black! I deleted the ground plane and the sky remains black. Jackson

Hmm... it even happens, when the model is unwelded ? Strange...
I sometimes had this kind of problem, when the cam was inside an object. Even worse, when passing a door.
So, for architecture, I don't "dig" rooms into massive house blocks, but construct them (as does the mason) from floor slabs, individual walls and so on, for each storey,
and keep them apart, don't bake nor bool'em.
This allows also, to duplicate and offset, to have different mats for the different faces.
But if this effect happens,
even when all elements are unwelded, so the cam isn't inside something, the reason must be elsewhere :(

Agiel & GP,

I know what is causing it now and how to fix it (although I don't understand why).

I closed the file without saving and reopened it. I didn't alter any materials, I just deleted the ground plane and the sky displayed correctly. I then inserted a new ground plane and the sky still displays correctly. So the original ground plane was causing the problem, although why it should is beyond me.

Many thanks for your help, if you hadn't sent me hunting for "fade out" colours I wouldn't have tracked down the ground plane as the culprit (even though the new ground plane has the original blue "fade out" colour anyway!)

Now that is a most peculiar glitch. I am glad you found the problem. Here is another work around, point your camera up towards the sky (with no ground plane or objects) do a quick render, save it, then apply it to the window as a jpg/bmp file and essentially treat it as if it were a background image of a sky like Thomas Krahn does. He has a tut if you want to see it.

Thanks Gary and/or Catherine, Not half as glad as I was! This has been such a breakthrough for me to finally be able to do reasonably realistic daylit interiors in Vue 5. Thanks for your advice, Jackson
